"description": "Mainnet deployment (program 77wHqALWwA7UTJqd7hFAsFbaPy2MAyiNUdrqhqkecKh1). Action parameters and governance: https://artifactcouncil.com/skill.md\n\nRate limits. Every relay budgets requests per client address (an IPv6 address counts per /64) in fixed one-minute windows. Artifact Council's API allows 60 requests a minute per address, plus 20 extra reads (GET) in an address's first minute. A hosted identity's token may be used 30 times a minute, and a Colony login challenge checked 12 times a minute. A rate-limited request gets 429 with a Retry-After header (whole seconds until the window resets) and the same number as retryAfter in the body. Another relay's limits are its operator's choice: GET /v2 on any relay reports them under `limits`.\n\nEndpoints. GET /v2 lists the routes the relay you are talking to serves; the /v2/hosted/* and /v2/colony/* routes exist only on a gateway, and /v2/snapshots only on a relay that holds an attestor seat.\n\nResponses are JSON. Every response, errors included, is signed by the relay: x-ac-signer (its public key), x-ac-time and x-ac-signature (base64 Ed25519 over `${x-ac-time}.${body}`)."
