The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

token_resolve unknown never probed
A symbol is not an identity. Dozens of contracts carry the symbol USDC and most of them are not the one anyone means. This endpoint returns all of them rather than silently picking one: every match carries its chain, contract, on-chain symbol, name and decimals read directly from the contract, whether its source is verified, its market cap rank when it is inside the top 250, and a canonical flag whose criterion is stated in the answer — a contract is canonical when the price directory lists it under that asset for that chain. Bridged and wrapped images are flagged with the evidence taken from the contract's own name or symbol, never inferred. When more than one match exists, ambiguous is true and a recommendation names one contract with its reason; that recommendation is about identity, not about whether to buy anything. Symbol matches with no on-chain code, and contracts the price directory does not know, are still listed, because hiding them is exactly how an agent ends up on a look-alike. Accepts "USDC", "0x…" or "coingecko:usd-coin". Preis 0.002 USDC je Aufruf, Abrechnung über x402.

contract_verification unknown never probed
Checks one address on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain against the open verification registry and against the chain itself. For a proxy the answer is deliberately split in two: whether the proxy is verified says almost nothing, whether the implementation it currently points to is verified is the real question, and both are reported separately with the implementation address read from the EIP-1967 storage slot, the EIP-1167 clone pattern or an implementation() call — with the evidence named in each case. Not verified means the source is not published here; it is not a statement about safety, and this endpoint deliberately makes none. similar_contracts_count would need a bytecode index this hub does not run, so it stays null and the runtime bytecode hash is returned instead, which is what such a lookup would need. Security judgements are made by /token/authorities, /contract/upgrade-risk and /token/report, not here. Preis 0.004 USDC je Aufruf, Abrechnung über x402.

honeypot_check unknown never probed
Runs each step separately as a simulation (eth_call with state override) against the current chain state and reports each result on its own, so a token that can be received but not moved on is visible as exactly that. Nothing is ever executed: no transaction is broadcast, no key is held, no approval is given. Limits, and they are decisive: can_buy and can_sell through a DEX router are NOT simulated - that needs a funded account and a router path this service cannot back, so both stay null. What IS tested is the transfer itself, which is where most traps sit. Balances are overridden at the account level, not inside the token contract storage, so a token that reads balances from its own mapping may report zero and the step then ends as "unklar" rather than as a pass. A negative result is no proof of fraud and a positive one is no clearance: the contract can change its behaviour after this check, and an owner with a tax switch can flip it at any time. That sentence belongs to every answer. Where the simulation does not carry, the verdict is "unklar" and the fields stay null. Preis 0.010 USDC je Aufruf, Abrechnung über x402.

token_restrictions unknown never probed
Scans the deployed bytecode for function selectors that grant control over trading, and reads the values that can be read directly. The decisive field is tax_modifiable: a tax of zero that the owner can raise to ninety-nine percent at any time is more dangerous than a fixed five percent, so the ability is reported, not just the current number. detection_method is given per field, because reading a selector out of bytecode is a different kind of evidence than calling the contract. Limits: current buy and sell tax are NOT simulated - measuring them honestly needs a forked node with a funded account, which this service does not have; the fields stay null and are listed in unavailable_fields rather than being guessed from the code. A selector found in the bytecode proves the function EXISTS, never that it is active or has ever been used - that distinction is carried in every finding. Not detected means null, never false.

arguments 18 lines
holder_concentration unknown never probed
Reads the holder list of an ERC-20 token from a public block explorer index and reports concentration. Addresses that do not represent a person or entity - liquidity pools, bridges, burn addresses and exchange custody - are excluded from the adjusted figure and every exclusion is listed with its evidence. The raw top-10 share is reported alongside so both numbers can be compared. Labels are only set when they can be backed by on-chain code or a public tag; otherwise the label is "unbekannt". Limits: holder lists come from a public index and exist only for Ethereum, Base, Arbitrum and Optimism - on Polygon and BNB Chain this call reports the field as unavailable instead of guessing. Tokens with very large holder counts may exceed the time budget of the index; the response then says so. The Gini value is computed over the examined holders only, not over the whole holder base. No statement is made about the people behind addresses. Preis 0.004 USDC je Aufruf, Abrechnung über x402.

liquidity_ownership unknown never probed
Reads the holders of an LP token and splits them into burned, locked in a named locker, and free. Burned and locked are two different things and are reported separately - burned is gone for good, locked comes back. A locker contract that is not in the curated table yields is_locker "unbekannt" rather than false, because an unknown lock contract is not the same as a demonstrably free holder. Limits: earliest_unlock_ts is NOT read - the unlock time lives inside each locker contract in its own layout, and decoding all of them honestly is beyond what this service can back; the field stays null and is listed in unavailable_fields. A lock that expires tomorrow is no lock, so treat locked_pct as an upper bound, not a guarantee. The holder list comes from a public index available for Ethereum, Base, Arbitrum and Optimism only. This endpoint takes the POOL address, not the token address - pool discovery for a token is a different question. Preis 0.006 USDC je Aufruf, Abrechnung über x402.

arguments 25 lines
token_authorities unknown never probed
Reads the contract itself rather than a project's claims. Ownership renouncement is checked, not believed: the zero address in owner() is evidence, a sentence in a whitepaper is not. Dangerous functions are found by their four-byte selectors in the runtime bytecode, and every finding names the function and the selector — a selector that is merely absent from the dispatch table is not reported. Whether a function is actually restricted is then tested by simulating the call from a neutral address that owns nothing: a call that goes through from there is a strong finding and is reported as such, a call that reverts with an access message is evidence of a guard, and anything else stays "unklar" instead of being interpreted. Nothing is ever signed or sent — every probe is a read-only simulation. A multisig owner is not the same as a single address, so the threshold and signer count are read from the owner contract and stated. Risk is a classification with all thresholds disclosed in the answer, not a score from a black box, and it is not investment or security advice. Preis 0.005 USDC je Aufruf, Abrechnung über x402.

arguments 32 lines
proxy_upgrade_risk unknown never probed
Upgradeability alone is not a finding — every serious protocol is upgradeable. The finding is who holds the key and how much warning holders get. This endpoint reads the proxy pattern from the EIP-1967 slots, the clone bytecode or an implementation() call, resolves the admin, checks whether that admin is a multisig by asking it for its threshold and signer count, and checks whether it is a timelock by asking for getMinDelay() or delay() — a timelock with a delay of zero is not a timelock and is reported as such, with the delay always given in seconds. The upgrade history comes from the contract's own Upgraded events with block, timestamp, previous and new implementation and the transaction hash, so a buyer can go and look. Public nodes limit log ranges, so the window actually searched is stated and an incomplete history is marked incomplete rather than presented as complete. The storage gap check reads the published source; without published source it stays null, which means unknown, not absent. Risk is a classification with every threshold disclosed, not advice.

token_unlock_monitor unknown never probed
Looks up a crypto asset by its exact NetSupply slug or an unambiguous symbol, then returns the scheduled releases inside a caller-selected window of up to 365 days. Unlock amounts remain decimal strings so large token quantities are not rounded. Each event states whether the schedule is enforced on-chain, how many lock objects it combines, when the promise was first recorded and how often it was revised. The percentage of float uses current circulating supply from CoinGecko, or a caller-supplied circulating_supply when reproducibility against another published supply figure matters. Current float is not projected float at the release date. Coverage is limited to schedules published by NetSupply; an empty list means no published event in the selected window, not proof that no private, discretionary or undocumented release exists. NetSupply attribution is included in every response as required by its commercial API licence. This is supply analysis, not price prediction or investment advice.

allowance_risk unknown never probed
Reads Approval events of one wallet from the chain, resolves the CURRENT allowance for every token and spender pair with a direct call, and weighs it against the balance actually held. An unlimited approval on an empty balance carries no risk and is reported as such. Every entry carries ready-made call data to revoke it - this service never signs and never sends anything, the caller decides. Limits: Approval events are read from a bounded block window, not from the whole chain history; the window is stated in the response as window_blocks and window_note, and approvals granted before it are missing. Spender labels are only set when a curated entry backs them, never guessed. last_used is not reported at all - proving when an approval was last drawn on would need a full transfer index this service does not have; the field is listed under unavailable_fields instead of being estimated.

tx_decode unknown never probed
Turns opaque call data into something an agent can reason about before signing. The method signature is resolved from the verified source of the contract first, then from this hub's own list of common signatures, then from the open selector directory — and the answer always names which of the three was used, because a four-byte selector is short enough to collide and colliding entries are listed. An unknown selector stays unknown: parameters are returned raw and nothing is guessed. Approvals and transfers are pulled out separately and unlimited approvals are flagged in warnings. For a mined transaction hash the receipt logs are decoded as well, which gives the transfers and approvals that actually happened rather than only those visible in the call data. Batching wrappers (multicall, aggregate3, Universal Router execute) are unpacked one level. This endpoint decodes only — it never executes, never simulates and never sends. What the transaction would do to your balances is answered by /tx/simulate. Preis 0.003 USDC je Aufruf, Abrechnung über x402.

tx_simulate unknown never probed

Answers the question that stands before every signature: what really happens to my assets and my rights. The call is executed against the state of a named block on a simulation interface, never on the chain — this hub holds no private key and broadcasts nothing. Balance changes are not inferred from events but measured: the same simulation reads every touched balance immediately before and immediately after the call, native currency included, so an outflow that emits no event is still visible. Approvals granted and revoked are extracted separately and unlimited ones are flagged. Where a public node offers a call tracer, the full internal call tree with depth and the number of storage slots written are included; where it does not, both fields are null and listed in unavailable_fields rather than approximated — currently Arbitrum and BNB Smart Chain have no free tracer. State overrides are supported for what-if questions. A revert is a valid, billable answer with its reason; a simulation that could not be run at all is not billed. The result holds for the stated block only — state can change before execution. Preis 0.012 USDC je Aufruf, Abrechnung über x402.

token_risk_report unknown never probed
Runs the identity resolver, the verification check, the authority scanner and the upgrade risk check against one token and merges them into a single answer. Nothing new is measured here: every statement carries the endpoint number it came from, so any finding can be re-bought individually and checked. A section that fails does not sink the report — it is set to null, listed in checks_failed with its reason, and the score is computed only over the checks that ran, with coverage stated. Sections this hub does not offer yet (taxes and restrictions, holder concentration, liquidity ownership, honeypot simulation, unlock schedule) are named explicitly in sections_not_covered rather than silently omitted, because a report that hides what it did not look at is worse than no report. The score is arithmetic with every deduction listed by name and amount and every threshold disclosed; it is a summary of measurements, not a verdict on a project. This is not investment advice and not a security audit — a contract can behave differently after this check, and a clean report is not a guarantee. Preis 0.014 USDC je Aufruf, Abrechnung über x402.

wallet_portfolio unknown never probed
Lists token and native balances of one wallet across chains and prices them where a price exists. priced_pct is mandatory and says how much of the portfolio is actually backed by a price - a total where a third of the holdings have none is not an answer without that number. Tokens that carry the marks of unsolicited airdrops are flagged with the reason but never silently removed; whether they count is the buyer decision. Holdings that cannot be priced appear in unknown_tokens with a reason instead of being set to zero. Limits: DeFi positions are NOT resolved - naming a position inside a lending or LP protocol needs per-protocol decoding this service does not have, so defi_positions stays empty and the field is listed under unavailable_fields rather than being guessed.

wallet_activity unknown never probed
Reads the transaction history of one wallet from a public block explorer index and groups it by kind of action. Classification follows the called contract and method, never the amount - a transfer to a known router is a swap, not a payment. Anything that cannot be backed by a method name stays in the category "unbekannt", which is a valid answer here: a large honest remainder beats an invented assignment. Limits: history comes from a public index available for Ethereum, Base, Arbitrum and Optimism only; other chains are reported under chains_failed instead of being guessed. The index is read page by page with a cap, so very busy wallets are truncated - truncated is then true and tx_count_index carries the full count the index reports. Gas spent in USD is not computed: it would need the native token price at the time of each transaction, which this service has no source for, so the field is listed under unavailable_fields.

wallet_pnl unknown never probed
Reads token movements of a wallet, prices every inflow and outflow at the time it happened, and derives cost basis, realised and unrealised profit or loss per asset. The method is stated because the result depends on it. Uncertainty is a mandatory field, not a footnote: an on-chain history knows nothing about deposits from exchanges, transfers between wallets of the same owner, or assets no price source covers. coverage_pct says which share of the movements carries a price; below sixty percent the answer is still delivered but marked as patchy, because a partial view honestly labelled is worth more than a confident wrong number. THIS IS NOT TAX ADVICE and not a tax computation - national rules decide holding periods, allowances and what counts as a disposal, and this endpoint knows none of them. Limits: transfers are read up to a cap per chain, so long histories are truncated; internal transfers of native currency are not included, only token movements; a transfer between two wallets of the same owner looks like a disposal here and inflates realised PnL - that is named in uncertainty.

wallet_classify unknown never probed
Derives behaviour classes from on-chain activity: share of swaps, regularity of intervals, hour-of-day spread, counterparty count and contract code. Several classes at once are allowed and usually more accurate than one. Every class carries its evidence; without evidence no class is set. automation_likelihood comes from measurable traits - interval regularity and how evenly activity spreads over the day - listed in features_used, never from a hunch. Limits: this classifies BEHAVIOUR, not people. No statement is made about identity, origin, intent or lawfulness, and nothing is ever marked criminal, suspicious or sanctioned. The history comes from a public index available for Ethereum, Base, Arbitrum and Optimism only, and is read up to a cap, so a very busy wallet is judged on its most recent activity - truncated says so.

counterparty_graph unknown never probed
Collects the addresses a wallet interacted with from its transactions and token transfers, counts the interactions per edge and names the type of each contract where it can be backed by a curated entry or a verified contract name. Depth is capped at two by design: anything deeper turns this into a tool for de-anonymisation, and that is not built here. Limits and the rule that matters: only contract designations and service types are reported. There is NO assignment to natural persons, no names, and no joining with outside data sources for identification. Shared on-chain activity is not evidence of a relationship between people - that sentence is part of every answer. The graph is capped in size and truncated says so honestly. History comes from a public index available for Ethereum, Base, Arbitrum and Optimism only. Volume in USD is not computed: it would need the price of every token at the time of every transfer, which this service has no source for. Preis 0.010 USDC je Aufruf, Abrechnung über x402.

cross_chain_balance unknown never probed
Reads token balances of one wallet on several chains from a public index and the native balance from the node itself. The same asset exists on several chains in different versions; canonical and bridged issues are reported separately and still summed, because both together are the answer. Every chain carries its block height, without which the sum cannot be checked. A chain that cannot be reached drops out with a reason under chains_failed and the call stays valid. Limits: the index exists for Ethereum, Base, Arbitrum and Optimism only. is_canonical is set from a curated table of the most common assets; where the table has no entry the field stays null rather than carrying a guess. Values in USD come from the index exchange rate where it has one - tokens without a rate are counted in the amount but not in total_value_usd, and priced_pct says how much of the value is actually backed by a price.

tx_status unknown never probed
Reads one transaction hash on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain and answers the question an agent actually has: did it go through, is it final yet, and what did it cost. Finality is defined differently per chain, so the rule used and the required block count are part of the answer instead of a single hard-coded number. A hash that no node knows is reported as "unbekannt", never as "fehlgeschlagen" — the two are not the same. A pending transaction whose nonce has already been consumed elsewhere is reported as "ersetzt", and the replacing transaction is searched for in the last 15 blocks; the search window is stated, so an empty result is not sold as proof of absence. Does not broadcast, sign or accelerate anything, and cannot tell you when a transaction entered the mempool — no node reports that. Preis 0.002 USDC je Aufruf, Abrechnung über x402.

bridge_track unknown never probed
Reads the source transaction on chain, identifies the bridge from the contracts it touched, and reports what actually left the wallet. overdue is measured against the usual duration of THAT bridge, and the comparison value is part of the answer - not against a fixed number. For bridges that need a manual claim, next_step says which step is missing and who has to trigger it; that is the real answer for a transfer that looks stuck. amount_delta shows what was deducted on the way, so a smaller arrival is visible rather than hidden. Limits: the destination side is NOT resolved - matching a deposit to its payout on the target chain needs a per-bridge message index this service does not have, so destination stays null and the field is listed under unavailable_fields. status is therefore derived from the source side and elapsed time only, never from an observed arrival. A bridge that is not in the curated table yields bridge_detected null instead of a guess. Nothing is executed and no claim is ever triggered. Preis 0.004 USDC je Aufruf, Abrechnung über x402.

fraud_graph_patterns unknown never probed

Analyzes only the transaction graph supplied in the request. It detects four mechanical graph patterns: directed rings, pass-through nodes that receive and send similar amounts within a configured time gap, star patterns around one high-degree node, and chain-like structuring where similar amounts move across several hops. Every pattern includes the edge ids that support it. The endpoint is stateless and deterministic, does not query blockchains or outside datasets, does not score people or wallets, and does not make an AML, fraud, sanctions, suspicious-activity or compliance decision.

chain_health unknown 12h ago
Queries every public RPC endpoint this hub knows for a chain in parallel — at least three, usually five — and reports what each one says instead of trusting one. Disagreement is the valuable finding: a single endpoint that lags or serves a different fork is exactly the failure mode this endpoint is built to expose, so agreement is reported per endpoint and the tolerance in blocks is derived from that chain's block time and stated. Beyond height it compares the actual block hash six blocks deep across endpoints; two different hashes at the same height mean the endpoints are on different chains. Endpoint names are given, never URLs, credentials or internal addresses. An endpoint this hub has rate-limited itself is marked self_limited with reachable null, because our own throttle says nothing about the endpoint. Supported chains: Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Smart Chain. This is a status measurement, not advice on which endpoint to use. Preis 0.003 USDC je Aufruf, Abrechnung über x402.

gas_estimate unknown never probed
Reads the fee history of the last 20 blocks on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain and returns what a transaction costs right now. Priority fees come from the 10th, 50th and 90th percentile of the tips actually paid in those blocks — the percentile used is named, not hidden. On rollups the L1 data fee is quoted separately from the L2 execution fee, because it is often the larger part and an estimate that merges them is simply wrong; the L1 part is computed from the chain's own gas price oracle for a synthetic payload of a stated byte size. Waiting times are derived from the measured average block time over the last blocks, not guessed, and the number of blocks assumed per speed level is disclosed. USD cost needs a price for the native currency from two independent sources; if neither answers, the USD fields stay null instead of being estimated. Arbitrum has no OP-Stack gas price oracle, so its L1 data fee is reported as unavailable rather than approximated. This is a measurement, not a recommendation.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
