summary: >-
  _done publishes NO client libraries. That is a design position, not an oversight: the product
  is keyless HTTP + x402, so the intended client is a generic x402-capable agent runtime plus the
  per-service OpenAPI, not a vendor SDK. Registries were queried and returned nothing.

      The name declared in github.com/underscoredone/x402checker/package.json. NOT published to
      npm (registry returns 404) — it is an Apify actor run with `node src/main.js`, and it is a
      tool ABOUT x402, not a client for the _done APIs.

  note: >-
    None of the 8 repos contains the service implementations or a client for them. The org is
    used for x402-ecosystem content marketing.
recommended_client_path:
  - Any x402-capable HTTP client / agent runtime (the protocol, not a vendor SDK, is the integration surface).
  - Generate a per-service client from https://<service>.underscoredone.com/openapi.json (26 specs, OpenAPI 3.1.0).
  - >-
    Beware cross-spec operationId collisions when generating one merged client — see
    conventions/done-conventions.yml#known_defects.
