    "description": "freeq is an IRC server where identity is an AT Protocol DID (via the\n`ATPROTO-CHALLENGE` SASL mechanism) rather than a nickname, plus a REST\nsurface so agents can read and verify conversations without speaking IRC.\n\n**Errors** — every `/api/v1/*` 4xx and 5xx answers with the `Error`\nschema: `error` (reason phrase, safe to branch on), `status`, `message`\n(prose, not stable), and `documentation`. A `429` carries `Retry-After`\nin seconds; a `401` carries\n`WWW-Authenticate: Bearer resource_metadata=…` (RFC 9728) naming the\nmetadata document that explains how to get a token.\n\n**Pagination** — list endpoints that can grow use one cursor pattern:\n`limit` (bounded, server-capped at 200) plus `before`, the unix-seconds\n`timestamp` of the oldest item on the page you already have. Absent\n`before` means newest first. Paging by timestamp rather than offset means a\npage cannot shift under a concurrent write. An empty array means the end;\nthere is no separate \"has more\" flag to disagree with the data.\n\nNote the cursor is the `timestamp` field, not `msgid`: msgids are ULIDs and\nsort the same way, but the server compares timestamps, so passing a msgid\nhere silently returns nothing.\n\n**Versioning and deprecation** — the path carries the major version\n(`/api/v1`). Additive change (new endpoints, new response fields, new\noptional parameters) happens in place, so clients must ignore fields they\ndo not recognise. Anything that removes or repurposes an existing field is\na new major path, `/api/v2`, served alongside `v1`. A version being retired\nis announced in `/llms.txt` and this document first, and its responses then\ncarry `Deprecation` and `Sunset` headers (RFC 9745 / RFC 8594) for at least\n90 days before removal. No endpoint has been deprecated to date.\n\n**Agent entry points**\n\n- `GET /api/v1/openapi.json` — this contract\n- `GET /.well-known/agent.json` — Agent Assistance Interface discovery\n- `GET /llms.txt` — markdown index for LLM agents\n- `@freeq/mcp` — MCP server wrapping this API and the IRC protocol\n  (in the repo under `freeq-mcp/`; not published to npm yet)\n- `@freeq/sdk` (TypeScript), `freeq-sdk` (Rust) — client SDKs\n\n**Reading conventions**\n\n- Timestamps are Unix seconds (integers) unless noted.\n- Message ids (`msgid`) are ULIDs, stable across federation.\n- Most read endpoints are unauthenticated for public channels; channels\n  with `+i` (invite-only) or `+k` (key) are excluded or return 403.\n- Anything that acts as a user takes a bearer token (see `security`).\n",
