last good check
of 28 tools
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.
execute unknown never probed
PAID: run code in an isolated, network-less sandbox and get stdout, stderr and exit code back. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to run.

FREE: read back an object you own, as base64. This is how what you bought with storage_buy comes back to you over MCP. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>').

PAID: atomically win a caller-named key for your own fleet -- an accountless compare-and-set. outcome "acquired" means you won it; outcome "held" is NOT an error, it means somebody already holds it and held.mine says whether that somebody is you -- the signal that stops a crash-resume or a duplicated retry doing an irreversible action twice. Keys are scoped to the PAYING WALLET: one payer's keys are invisible to every other payer. Inspect it with claim_read, give it up early with claim_release, extend it with claim_renew. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

PAID: extend a hold you already have without losing your place in line -- the heartbeat that lets a lease be SHORT (so a crash frees it fast) while a live holder keeps it alive by paying again. Re-acquiring with claim_acquire deliberately does NOT extend, so a retry loop cannot hold a key indefinitely by accident. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

FREE: win a caller-named key for 300 seconds, or learn who already holds it. Unlimited distinct keys per wallet, renewable by calling again. A sibling of claim_acquire, not a discount on it: this lease is 12x shorter than the cheapest paid plan, so a lock that has to survive a deploy, a batch or a day is on the paid ladder from the first minute. The free-acquire signature has its OWN domain, distinct from the read and release domains, so neither of those can be replayed into an acquire. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>').

FREE: who currently holds this key, if anyone -- scoped to YOUR wallet, so a stranger cannot probe your namespace. Checking your own lock must not cost again, or a fleet polling its own hold is charged for not doing work twice. A key nobody holds answers with claim: null, never a not-found: "is this free?" is a legitimate question with a legitimate negative answer. The read signature cannot release the key. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>').

FREE: give up a key you hold before it expires, so the next racer does not have to wait out your hold. Release signs its own domain-separated message, distinct from the read domain, so a captured inspect proof can never double as a lock-breaking order. The signature proves the WALLET and does not by itself authorize the release: holder is separate and unsigned, and the release is refused unless it names the CURRENT holder (CLAIM_NOT_YOURS) -- what stops one member of your fleet breaking a sibling's lock. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>').

PAID: we fetch a URL from OUR vantage point and return a signed, timestamped attestation of what we saw -- hash, byte count, HTTP status and headers, never the body itself. Read it back afterwards for free with attest_read, so the id can be cited to a THIRD PARTY who never paid us and who can verify the signature themselves. A fetch that fails to connect, times out, or is refused for safety is still billed and still signed: the observation is what is sold, not a guaranteed 200. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

FREE and unauthenticated: read a previously-created attestation back by id, with its signature. This is how what you bought with attest_create comes back over MCP -- and deliberately NOT wallet-scoped, because the whole point is that a third party who never paid can fetch it and check the signature.

PAID: deposit a typed briefing for the process that takes over from you -- what is DONE (every entry carrying evidence of how it was verified), what is NOT done, what was IN FLIGHT at the cut, and what to pick up FIRST. Returns an id; the successor reads it back for free with handoff_read, with no identity, header or payment of any kind, so neither side needs an account with us. Retained 3 days. The done section is structurally forbidden from holding an unverified claim: a briefing cannot assert something is finished on intent alone. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

FREE and unauthenticated: read a briefing back by id. This is how what you bought with handoff_deposit reaches your successor over MCP. Deliberately needs no signature -- the successor is by construction a DIFFERENT process and may hold no wallet at all, so demanding proof of the payer would make the product undeliverable.

PAID: register an intent you are about to act on irreversibly, with a lease and a verification probe (a GET plus a predicate). Confirm before the lease expires with deadman_confirm, free -- otherwise, once the lease lapses, we run your probe and publish the verdict: confirmed-by-probe, refuted-by-probe, or unresolved (a first-class, honest outcome when the probe could not complete -- never guessed as refuted). The raw probe response is published beside the verdict via deadman_read, free, so you can re-run it and check our answer rather than simply believing it. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

FREE: the live caller closes the loop before the lease expires, so the probe never runs. Deliberately NOT wallet-scoped -- possession of the id is the entire authorisation, since the confirming call may have no wallet of its own. Refused, never a silent no-op, once the entry has left pending: confirming an already-resolved entry could otherwise overwrite a probe verdict with a claim from a caller who may not even be the process that registered it.

FREE and unauthenticated: read an entry back by id, including its verdict and the raw probe response once resolved. This is how what you bought with deadman_register comes back over MCP. If the lease has lapsed and nobody has resolved it, the probe runs right here, synchronously, before answering -- each entry can trigger at most one live probe, ever.

PAID: buy paid placement for a listing you own in this directory -- it ranks above free rows and reads tier "paid" for the life of the plan. Pay from the WALLET THAT OWNS the listing; no other proof is asked for and no other wallet can promote it. Promoting an already-promoted row EXTENDS it rather than replacing it, so renewing early never costs you the time you already paid for. Find the id, the live price table and the current paidUntil for free with search_listings.

PAID: we re-fetch a venue we have snapshotted before, from OUR vantage point, and return what changed since the baseline -- the schema/rubric fields that moved, were added and were removed, not a byte diff. The answer to "did this venue quietly change its rules under me?" for an agent that cannot keep its own corpus. No drift is still an answer and is still billed: the comparison is what is sold. Aim it with drift_venues (which venues we hold) and drift_baseline (what we hold for one), both free.

FREE: every venue id drift_check can be aimed at, with what we hold for each. A closed value set, not a pattern: without it a caller can honour the input schema and still never name something buyable, which is a paywall on discovery rather than on work.

FREE: the baseline snapshot we hold for one venue -- what a paid check would diff against, and when it was taken. Reading what you are about to buy a comparison against must not cost, or the first call is a blind one.

PAID: we poll a URL from OUR vantage point on your interval until your predicate matches or the ttl runs out, and keep the verdict for you to collect -- a wait that survives your own process dying, which is what an agent cannot do for itself. Price is a function of intervalSeconds x ttlSeconds (interval 60..86400s, ttl 60..604800s), so a first unpaid call quotes YOUR request rather than a fixed plan. The reply carries the id: read it back any time, free and as often as you like, with watch_read.

FREE: the current state of a watch you registered -- active, matched or expired, with the observation that matched. The id is the capability, so a successor process handed the id can collect the verdict without your wallet. Reading never triggers a poll and is never charged: polling your own pending answer must not cost again.

What agent-exec sells, what it costs, and exactly where to pay for it. This tool call itself is free and moves no money. Code execution can be bought right here, with the paid execute tool (x402 over MCP), or over plain HTTP at the URLs this returns.

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.
[](https://brick.blue/agent/b2e44b883117f45b)
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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
