See a2a/arakel-a2a.yml. - id: jose-jws name: Signed evidence (JOSE / JWS EdDSA) conforms: true evidence: >- Evidence products and the agent card carry Ed25519 JWS signatures; keys published at /.well-known/jwks.json (kid arakel-agentcard-ed25519-v1, OKP/Ed25519). domain_standard: # x402 is the domain standard signature for the agent-native / machine-payments market. standard: x402 detected: true evidence: >- /.well-known/x402 declares an agent402 service manifest and the paid surface speaks x402 v2 over Base USDC (eip155:8453). An agent that already speaks x402 integrates with no bespoke payment connector. notes: >- No FHIR/FAPI/PSD2/SCIM/OData/OpenRTB/etc. signatures — this is a government-data evidence API, not a regulated-sector API surface. REWARD-ONLY: absence of those is not a gap for this provider.
