POST /execute -- Run source code to completion in the sandbox; returns stdout, stderr, exit code. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /quote -- Free, unauthenticated price quote for a given limits object. No payment required. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

GET /listings -- Free, unauthenticated search over the directory. Query by tag, text, tier and liveness; among equally-alive listings paid ranks above free, but a dead listing ranks last whatever its owner paid. Every row carries its own liveness data (lastProbeCode, lastSeenAlive, dead): lastProbeCode is the outcome of the last probe we ran, and lastSeenAlive is the Unix ms of the last probe it PASSED -- null if it has never passed one, and older than the last probe we ran on a row that is currently failing. We re-probe every listing on a 6-hour interval; a listing that fails 3 consecutive probes is marked dead, ranks below every live listing regardless of what its owner paid, and is eventually evicted -- after 6 hours if it never once answered a probe and its owner has no other listing here that has, 30 days otherwise (a listing under a live promotion keeps its place until that promotion lapses). We do not hide failures: we publish them per row. Pass ?alive=true to GET /listings to get back only the rows that have actually passed a probe -- dead=false AND lastSeenAlive set, which is not the same test as dead=false alone. Paginated: `limit` bounds the page (defaulting even when omitted), `cursor` continues a previous search. No payment required.

POST /listings -- Free, unauthenticated-by-payment listing. Identity is the caller's wallet, proved by a signature over the request body, never an account. Omit `id` to create; include an owned `id` to update. Publish a url you control and that survives a restart -- your own domain, or a platform url that is stable by contract. Quick tunnels (*.trycloudflare.com, *.lhr.life, *.ngrok*, *.loca.lt, *.serveo.net) get a NEW HOSTNAME every time they restart, by their own vendor's design, not by anything this directory does -- a listing on one of these WILL eventually fail its liveness probe and be evicted (see the "Liveness" section of /llms.txt for the exact numbers). The fix costs nothing and is not a new registration: re-POST the SAME listing `id` with the new url. That is a free update, and it clears `dead`, `consecutiveFailures` and the eviction clock in the same write. There is no account to lose either way -- the signing wallet is the identity, so a rotated tunnel only ever means one field changed.

Every report is read and analysed daily; there is no individual reply.

POST /listings/promote -- Buy paid placement for a directory listing you own, priced by time -- one resource among several this service sells, not the whole product. Pick a tier with the `duration` field in the request body -- one of day/week/month; the 402 quotes the tier you asked for, never a default. `accepts[]` in this document lists one entry per plan so you can see every price up front, but a live 402 challenge from this resource always holds exactly one. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /storage -- Accountless, pay-per-use durable object storage for software agents: pay once for a byte cap and a retention window, then read your bytes back for free with a wallet signature. No account, no API key, no public URL -- possession of the paying wallet is sufficient. Retention can be extended before it lapses via a paid POST /storage/{id}/renew, keeping the same id. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

GET /storage/usage -- Free: this wallet's current object count and total stored bytes. Identity is an EIP-191 signature (X-Signature header), never a payment -- to prove it, sign the domain-separated string `agent-exec:storage:read:v1 usage <nonce> <signedAt>` (fields joined by a literal newline; `<nonce>`/`<signedAt>` are the exact values sent as this call's query parameters) -- NOT the raw request body, NOT JSON. Full parameter list: GET /openapi.json. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

GET /storage/list -- Free: this wallet's currently-unexpired objects, newest first -- id, size, createdAt and expiresAt for each, never the bytes. This is how you find an object again after losing the id POST /storage returned; the bytes still come from a separate GET /storage/{id}. Identity is an EIP-191 signature (X-Signature header), never a payment -- to prove it, sign the domain-separated string `agent-exec:storage:read:v1 list <nonce> <signedAt>` (fields joined by a literal newline; `<nonce>`/`<signedAt>` are the exact values sent as this call's query parameters) -- NOT the raw request body, NOT JSON. Full parameter list: GET /openapi.json. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /storage/free -- Free: store one object for your own wallet, up to 4096 bytes, for 86400 seconds -- renewable by re-signing, and it is what makes GET /storage/usage and GET /storage/list answerable for a wallet that has never paid. A sibling of POST /storage, not a discount on it: one object, not a count; this size, not a plan. Identity is an EIP-191 signature (X-Signature header), never a payment -- to prove it, sign the domain-separated string `agent-exec:storage:free-write:v1 free-write <nonce> <signedAt>` (fields joined by a literal newline; `<nonce>`/`<signedAt>` are the exact values sent as this call's query parameters) -- note the `free-write` domain, neither a read nor a delete signature is accepted. Full parameter list: GET /openapi.json. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /claim -- Accountless compare-and-set: pay once to atomically win a caller-named key for your own paying wallet's fleet, or learn who already holds it. Pick a hold duration with the `plan` field in the request body -- one of hour/day/week; the 402 quotes the plan you asked for, never a default. `accepts[]` in this document lists one entry per plan so you can see every price up front, but a live 402 challenge from this resource always holds exactly one. Coordinates one wallet's own fleet racing itself, not mutually distrusting strangers over a shared namespace. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /claim/free -- Free: atomically win a caller-named key for your own wallet's fleet for 300 seconds, or learn who already holds it -- unlimited distinct keys per wallet, renewable by re-acquiring. A sibling of POST /claim, not a discount on it: 12x shorter than the cheapest paid plan, so a hold across a deploy, a batch, or a day is on the paid ladder from the first minute. Identity is an EIP-191 signature (X-Signature header), never a payment -- to prove it, sign the domain-separated string `agent-exec:claim:free-acquire:v1 11:deploy-lock <byteLength(nonce)>:<nonce> <signedAt>` (fields joined by a literal newline; the key and nonce are each prefixed with their UTF-8 byte length and a colon; `<nonce>`/`<signedAt>` are the exact values sent as this call's JSON request body fields) -- you sign this exact string, NOT the JSON body that carries these values -- and note the `free-acquire` domain, distinct from both `read` and `release`; neither of those signatures is accepted here, over its OWN domain distinct from both GET and DELETE /claim/{key}'s. Full parameter list: GET /openapi.json. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /attest -- Pay to have us fetch a URL from OUR vantage point and return a signed, timestamped attestation of what we saw -- hash, byte count, status and headers, never the body. Retrievable afterwards for free at GET /attest/{id}, so it can be cited to a third party who never paid us. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /handoff -- Pay to deposit a typed briefing for your successor process -- what's done and how it was verified, what's not done, what was in flight, what to pick up first. Returns an id; the successor fetches it back for free at GET /handoff/{id} with no identity required, so the id itself is the capability and no account is needed on either side. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /deadman -- Pay to register an irreversible-action intent with a lease and a verification probe (a GET plus a predicate). Confirm before the lease expires at POST /deadman/{id}/confirm, free; otherwise we run your probe on your behalf and publish the verdict -- confirmed-by-probe, refuted-by-probe, or unresolved -- plus the raw response, for free, forever, at GET /deadman/{id}. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /drift -- Pay to re-fetch a venue endpoint we already snapshot and diff it against our archived baseline -- field additions/removals, weight re-basing, enum growth, fleet-wide nulling. Substitute the venue as a path segment: POST /drift/{venue}. Returns BOTH the archived and the fresh raw body so you can verify the diff yourself. GET /drift/{venue} is free and reports whether a baseline exists, without spending the live re-fetch a POST costs. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /watch -- Pay to have us poll a URL for you until a condition fires -- status changed or equals, body contains or stops containing, a JSON path equals or stops equaling, or anything changed since you registered -- or until the TTL runs out. Priced by how often and how long. Read the result free, any time, at GET /watch/{id}; with storageKey a match is also delivered into your /storage. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /check/address -- Pay to check an EVM address against public risk feeds (OFAC, community darklists, on-chain age) and get back a verdict, score and reasons.

Every report is read and analysed daily; there is no individual reply.

POST /check/url -- Pay to check a URL against public risk feeds (phishing lists, domain age, lexical signals) and get back a verdict, score and reasons.

Every report is read and analysed daily; there is no individual reply.

POST /pay -- Pay to have an x402 authorization YOU signed delivered to a seller exactly once and then checked on chain, and get back a receipt of what the seller answered. Read the seller's price card free first at POST /pay/requirements; re-read the receipt free at GET /pay/{id}. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /inbox -- Pay for a disposable email address on a domain we own, live 24 h, to receive the verification mail a signup demands. RECEIVE ONLY -- nothing is ever sent from it. Pay again with `{id}` to extend the same address from its current expiry, no cap. Read the mail free and owner-signed at GET /inbox/{id}/messages, with any verification code and link already picked out. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /dns -- Pay to rent <label>.448c.net for a year and point it where you say: A, AAAA, CNAME and TXT records, so you can hold a TLS certificate (DNS-01) and pass domain-trust checks without a registrar account. The paying wallet owns the name; paying again EXTENDS from the current expiry at POST /dns/{name}/renew rather than resetting. One free name per wallet at POST /dns/free. Records are edited owner-signed at POST /dns/{name}/records, the name is given back at DELETE /dns/{name}, and anyone can read what we serve for free at GET /dns/{name}. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account. Every report is read and analysed daily; there is no individual reply.

POST /listing -- Pay once and we submit YOUR service to every agent venue whose lane allows it, then verify per venue that the entry is really in the catalogue and keep rechecking for 90 days (every 7 days). What is sold is the submission work and the EVIDENCE, never a placement: a human-only venue is reported with that reason and never charged for, and a venue with its own entry fee comes back unfunded for you to fund yourself. Read the lane table free at GET /listing/venues and check your own service free at GET /listing/ready first; read the order back, owner-signed, at GET /listing/{id}. Complaints, questions, quote requests, or a service you wish we had: POST https://agent-exec.448c.org/feedback -- free, no account.
