_ used through this hub 30 days

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.

_ paid on base 30 days

Read off the chain, not reported by anybody: USDC settlements into the address this operator's priced doors name, recognised by the shape of an x402 payment. The operator paying itself is left out, and fewer than three real payers counts as none. This address also stands behind 1 other origin: the figure is the gateway's, not this listing's alone. How it is counted.

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.

  • verify-receipt 0.005 USDC paid never probed

    For the party who was HANDED a receipt: checks one genesis402 proof receipt against this rail's published Ed25519 issuer key and reports the verdict (valid / signature_mismatch / unverified / not_found), the receipt's truth labels, subject, claim, digest, issue time, sequence number and previous-hash link, the issuer key id and public key, and the chain's current head. The response states plainly that the chain is not externally anchored, so a valid verdict proves the rail issued the receipt and has not altered it since — not that the rail could not have back-dated its own chain.

Returns sha256, sha512-256 and blake2b512, the canonical form's byte length and a preview of it, so a counterparty can independently reproduce any evidence_hash this rail publishes.

    The merkle root of up to 4,096 leaves, built with sorted pairs and duplicated odd nodes — the OpenZeppelin MerkleProof convention that airdrop and allowlist contracts verify against. Choose keccak256 (EVM default) or sha256. The tree depth and leaf count are reported so you can check the shape matches what your contract expects. Uses sorted-pair hashing. A tree built with unsorted pairs or a different odd-node rule produces a different root; this states its convention rather than leaving you to guess.

    Sweeps all ten chains at once and reports, per chain, the native balance, the number of transactions sent, and whether bytecode is deployed — so you learn where an address is actually active instead of guessing a chain and reading a zero. Chains whose RPC did not answer are listed separately and never counted as inactive. Activity is inferred from nonce, balance and code. An address that only ever RECEIVED tokens has a zero nonce and may show as inactive on this measure; the balance field is what catches that.

The free public Solana node this rail uses answers null for some SPL token MINT accounts even though they exist, so a null result here is reported as not-found and is not proof the account is absent.

    APR to APY or back, for a compounding frequency you choose — daily, monthly, or any number of periods — with continuous compounding given alongside as the theoretical ceiling. The gap between the two is what quoting APR instead of APY hides. Pure arithmetic on the rate you supply. It says nothing about whether a quoted yield is real, sustainable or safe.

    When an address first and last transacted, how many transactions it has, and a sample of its most recent distinct counterparties. A wallet created an hour ago with two transactions is a different counterparty risk from one active for three years, and this is the cheapest way to tell them apart. Explorer-indexed activity on ONE chain. An address can be old and busy elsewhere. Age is not trustworthiness — patient attackers age wallets deliberately.

    One amount expressed every way at once: raw base units, gwei, ether, and the decimal form for whatever token decimals you name. Say whether your input is in base units or whole units; the conversion is exact big-integer arithmetic, never floating point. Deterministic: identical input always yields identical output.

  • ens-resolve 0.005 USDC paid never probed

    Takes an ENS name, computes its namehash, finds the resolver the registry has recorded for it, and asks that resolver for the address — reporting each step, so an unresolved name tells you whether it has no resolver set or a resolver that returns nothing. Mainnet ENS only. A name with no resolver and a name whose resolver returns the zero address are different situations and are reported differently. Offchain (CCIP-read) resolvers are not followed. Read live at request time; every figure names the exact endpoint it came from, and an upstream that does not answer is reported as unavailable — never as a zero.

Values are returned as strings — no type inference, because guessing that "0123" is a number is how zip codes and account ids get corrupted.

Compute it before you sign to confirm the wallet is showing you the same thing, or after to verify what somebody else signed. Your type definitions are taken as given; a wrong type set produces a valid-looking digest for the wrong data, which is exactly the trap EIP-712 exists to close. Check the domain fields carefully — chainId and verifyingContract are what stop a signature being replayed elsewhere. Deterministic: identical input always yields identical output.

  • solana-tx unknown never probed

    A confirmed Solana transaction: slot, block time, fee in lamports and SOL, success or the error the runtime returned, the accounts it touched, and the pre/post balance deltas for both SOL and SPL tokens — which is how you see what a transaction actually moved rather than what it claimed. Public RPC nodes prune history; an older signature may return null even though it existed. Null is reported as not-found, never as failed. Read live at request time; every figure names the exact endpoint it came from, and an upstream that does not answer is reported as unavailable — never as a zero.

_ try it over a2a 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.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

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
0

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.
