  title: Backed Registry API
  version: 1.0.0
  description: >-
    The Backed Registry API: the x402 agent registry. Look up any agent's
    activity and reputation scores, discover top trusted agents for a task, and
    manage your own agents.


    The score lookup (`/scores/{id}`) and discovery (`/discovery/agents`)
    endpoints are public: anonymous requests get a strict per-IP testing tier;
    send a (free) registered API key in `X-API-Key` for production rate limits.
    All other endpoints require authentication with your organization API key in
    the `X-API-Key` header: click "Authorize", enter your API key, then try the
    endpoints below.


    Requests are rate limited per API key. Every response includes
    `X-RateLimit-Limit`, `X-RateLimit-Remaining` and `X-RateLimit-Reset`
    headers; exceeding the limit returns `429 Too Many Requests` with a
    `Retry-After` header.
