summary: >-
  The AUX Evidence and Certification API is public: the OpenAPI declares no securitySchemes and no top-level
  security, and the provider states in llms.txt, aux.json (access.public_counterparty_profile) and the quickstart
  that "no account, API key, payment, or package installation is required for the public counterparty check". Every
  operation was reachable anonymously in this pass (public GETs returned 200; POSTs with empty bodies returned the
  API's 400 validation envelope, not 401). The single authenticated operation is handoff consumption, which
  authenticates the RECIPIENT with a short-lived ES256 JWS assertion verified against a key the recipient publishes
  on its own domain — a domain-anchored, key-based scheme rather than an API key or OAuth. Trust in the opposite
  direction (agent verifying AUX) is by ES256 receipt signatures against the published JWKS.
schemes:
- id: public
  type: none
  applies_to: all operations except consumeAuxCertificationHandoff
  detail: No credential of any kind; CORS is open (access-control-allow-origin *). An abuse limiter is present per /api/health but no limits are published.
- id: recipient-domain-jws
  type: http
  scheme: signed-assertion
  applies_to: [consumeAuxCertificationHandoff]
  location: request body field consumer_assertion.jws (not an Authorization header)
  format: JWS Compact Serialization
  algorithm: ES256
  typ: AUX-HANDOFF-CONSUMER+JSON
  max_lifetime_seconds: 300
  key_discovery: https://{recipient_domain}/.well-known/aux-handoff-consumer.json
  signed_fields: [schema, issuer, subject, audience, recipient_domain, recipient_agent_id, handoff_id, handoff_sha256, intended_action, jti, issued_at, expires_at]
  failure: 401 "Recipient authentication or binding failed" (outcome RECIPIENT_AUTHENTICATION_FAILED)
  docs: https://api.aux.prdictionedge.ai/v1/certification-handoffs/consume
  note: Documented by the machine-readable contract the GET on the same path returns (consumption_version aux-handoff-consumption-0.1.0).
- id: source-attestation-jws
  type: http
  scheme: signed-assertion
  applies_to: [verifySourceAttestation, certifyTransaction, createCertificationAttempt]
  location: request body source_attestations[].jws with source_domain
  format: JWS signed by a private evidence source; AUX resolves the source domain's published trust document and key itself
  docs: https://api.aux.prdictionedge.ai/v1/evidence/source-attestation
  note: Not caller authentication — it authenticates third-party evidence the caller transports.
