attest_create
Signed observation of a URL (paid, x402)
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. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

attest_read
Read an attestation (free)
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. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

check_address
Check an EVM address against public risk feeds (paid, x402)
PAID: check an EVM address against public risk feeds (OFAC, community darklists, on-chain age) and get back a verdict, score and reasons in the same response the payment settles -- there is no separate read-back call. Charged only on success: if every risk feed is unreachable the request is refused for free (CHECK_SOURCES_UNAVAILABLE) rather than answered with an unsourced verdict. 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.

check_url
Check a URL against public risk feeds (paid, x402)

claim_acquire
Take a named lock (paid, x402)
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.

claim_acquire_free
Take a named lock for 300 seconds (free)
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>'). Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

claim_read
Who holds this key (free)
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>').

claim_release
Give up a lock you hold (free)
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>').

claim_renew
Extend a lock you hold (paid, x402)
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.

deadman_confirm
Close the loop on an intent (free)
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.

deadman_read
Read an intent and its verdict (free)
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.

deadman_register
Register an intent with a verification probe (paid, x402)
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.

drift_baseline
The baseline we hold for one venue (free)
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. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

A venue we have never snapshotted is a free 404, never a charge.'}}, 'additionalProperties': False}
drift_check
Re-fetch a venue and diff it against our baseline (paid, x402)
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. 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.

drift_venues
Which venues we can check for drift (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.

handoff_deposit
Deposit a briefing for your successor (paid, x402)
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.

handoff_read
Read a briefing (free)
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. Possession of the id is the entire authorisation; treat it as a secret. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account.

listing_promote
Buy paid placement for a directory listing (paid, x402)
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. 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. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account.

search_listings
Search the agent-exec directory
Free, unauthenticated search over agent-exec's directory of paid agent-facing services (same data as GET https://agent-exec.448c.org/listings). Returns a page of listings and an opaque cursor for the next page.

service_card
agent-exec service card
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. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

storage_buy
Store an object (paid, x402)
PAID: store opaque bytes for the life of the plan you buy, owned by the wallet that pays, readable with no account. Returns the object id and when it expires; read it back with storage_read, extend it with storage_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. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

storage_delete
Delete a stored object (free)
FREE: delete an object you own before it expires, and free its bytes. There is no refund and no undo. 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>').

storage_list
List your stored objects (free)
FREE: list the objects your wallet owns -- id, label, size, when each was created and when it expires -- one page at a time.

storage_read
Read a stored object (free)

storage_renew
Extend a stored object (paid, x402)
PAID: push an object you own further out, by buying it another plan term. The object is untouched; only its expiry moves. Returns the new and previous expiry. 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.

storage_replace
Replace a stored object (paid, x402)
PAID: overwrite the contents of an object you own, keeping its id, and buy it a fresh plan term at the same time. Omit label to keep the current one, pass an empty string to clear 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.

storage_usage
Your storage usage (free)
FREE: how many objects your wallet is storing and how many bytes they occupy. 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>').

watch_read
The state and verdict of a watch (free)
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. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

watch_register
Durable poll of a URL until a condition fires (paid, x402)
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. 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. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account.
