summary: 'Three access modes on one host, none of them OAuth: (1) keyless — the MCP endpoint, POST /v1/batch and
  the /v1 robot/ground-truth/notary/anchor routes need no credential at all; (2) a static X-API-Key header, issued
  instantly by POST /signup with no card, required for per-user state (watchlist, webhooks, /v1/me), the direct
  per-feed GET routes and /status; (3) x402 payment — /v1/pro/* return HTTP 402 with a USDC-on-Base quote and are
  unlocked by an X-PAYMENT header from an x402 client, no account. The OpenAPI models the key as an optional `x-api-key`
  header parameter on 60 operations (alongside x-rapidapi-proxy-secret / x-rapidapi-user for the RapidAPI marketplace
  channel) rather than as a securityScheme.'

  type: apiKey
  in: header
  name: x-rapidapi-proxy-secret / x-rapidapi-user
  applies_to: the same 60 keyed operations, when called through the RapidAPI marketplace listing
  note: Declared as optional header parameters in the OpenAPI; the marketplace injects them. Not a credential a
    direct caller uses.
  verified: derived from the contract
oauth2:
  supported: false
  evidence: /.well-known/oauth-authorization-server, /.well-known/oauth-protected-resource and /.well-known/openid-configuration
    all return 404; no securitySchemes in the contract.
response_signing:
  note: 'Authentication of the SERVER to the client is the stronger half of this profile: every response is Ed25519-signed
    (DF-VERIFY/1) and the agent card carries a JWS. See conventions/dynamicfeed-ai-conventions.yml response_envelope
    and json-schema/.'
gaps:
- No securitySchemes in the OpenAPI, so generated clients see every route as anonymous.
- No key rotation or revocation endpoint.
- No scoped or restricted keys; one key grants all per-user routes.
- No OAuth/OIDC, so no delegated identity path for agents acting on behalf of a user.
