note: >-
  The OpenAPI declares no securitySchemes; the auth model is documented in the self-describing /api/ index
  (auth block), llms.txt and llms-full.txt. There are no accounts anywhere: every credential is a no-signup
  bearer token or a per-request x402 payment.
schemes:
  - id: public
    type: none
    description: >-
      Public, no credential. Search (GET /api/busca), tender sheets (GET /api/compra/{id}), CNAE dictionary,
      health, discovery documents and feeds are free and unauthenticated. Documents of tenders published 30+
      days ago are free samples on the same anonymous surface.
  - id: owner-token
    type: http
    scheme: bearer
    token_prefix: edm_
    description: >-
      Owner token sent as Authorization Bearer. Created by POST /api/dono with no signup; the response also
      returns the whsec_ webhook signing secret. Only a hash of the token is stored server-side. Gates the
      alert, watcher and owner-state routes (auth: owner in llms.txt).
    create: POST /api/dono
  - id: credit-token
    type: http
    scheme: bearer
    token_prefix: cred_
    description: >-
      Prepaid-credit bearer token, sent as Authorization Bearer (or the X-Credito header). Bought once via
      POST /api/credito?usd={1|5|10|25} paid with x402; returned exactly once; debits any paid route across
      all the operator's products ("vale em todos os produtos da casa"). Not an account - a pure bearer.
    create: POST /api/credito
  - id: x402
    type: payment
    scheme: x402
    description: >-
      Per-request machine payment. A paid route called without payment answers HTTP 402 with an accepts[]
      offer; the client pays (USDC) and repeats the request with the X-PAYMENT header. No registration.
      Every paid delivery returns x-editalmd-recibo and x-editalmd-sha256 headers and a receipt at
      GET /api/recibo/{id}.
webhook_signing:
  scheme: standard-webhooks
  secret_prefix: whsec_
  headers: [webhook-id, webhook-timestamp, webhook-signature]
  algorithm: HMAC-SHA256 of "id.timestamp.body" with the base64-decoded secret, signature as "v1,<base64>"
  rotation: POST /api/dono/segredo - previous secret still signs for 24 hours
