What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of agent-exec.448c.org controls every word below.
Execute code
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.
Promote a directory listing
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.
Store an object
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.
Claim a key
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.
Attest a URL
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.
Hand off context to a successor
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.
Register a dead-man's journal entry
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.
Diff a venue against our archived baseline
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.
Watch a URL until a condition fires
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.
