Codex Pets Developer Portal

Build against the public Codex Pets registry with OpenAPI, MCP, JSON endpoints, TOON mirrors, and explicit authentication notes.

Start with MCP

codex mcp add codexPets --url https://pets.ydb-qdrant.tech/mcp

The MCP server is read-only and exposes approved public pet data plus request workflow discovery.

OpenAPI JSON: Canonical OpenAPI 3.1 specification for public Codex Pets endpoints.
API docs: Human-readable API docs for JSON, TOON, MCP, request, and submission routes.
Full LLM context: Expanded markdown context with API reference, auth notes, examples, and webhooks status.
MCP metadata: MCP Registry metadata for the public Streamable HTTP server.

Public read endpoints do not require authentication.
AppSessionCookie is used by browser account flows and optional signed-in request attribution.
ProxyBasic is supported when the deployment is protected by a trusted reverse proxy.
OAuth 2.0 is not currently supported.
Webhooks are not currently available.
