    at the legacy /.well-known/agent.json (108,343 bytes both). Ownership is not in question: the card''s provider.organization
    is Sirenic with provider.url https://api.sirenic.eu, the same host serves the OpenAPI (servers[] https://api.sirenic.eu,
    contact contact@sirenic.eu), the RFC 9727 api-catalog names this exact URL as ''A2A agent card'', and sirenic-eu/sirenic-examples
    on GitHub ships examples/a2a.ts against it.'

  name: Sirenic
  description: 'Pay-per-call French & European company data (official registers: INSEE Sirene, INPI RNE, NBB, Zefix
    and 8 more, plus worldwide entities via LEI/GLEIF). Every skill is a paid HTTP resource: send a JSON data part
    {"path": "/v1/..."} or {"skill": "<id>", "params": {...}}; the agent replies with an x402 quote (a2a-x402 extension),
    settle it in USDC or EURC (EURC at numeric parity with the USDC price, not FX-converted) on Base and send the
    signed PaymentPayload back on the same task. Paying in EURC requires an explicit client opt-in since @x402/core
    2.23 (spendControls.allowedAssets), otherwise your client silently keeps the USDC option. Set allowedAssets[].maxAmountPerPayment
    as well (integer ATOMIC amount, e.g. "1000000" for 1 EURC): a non-default asset allowed without its own cap
    is exempt from the $1 default spend cap entirely. Your x402 client also refuses, by default, any quote above
    $1.00 per payment (spendControls.maxAmountPerPayment); only GET /v1/kyb/batch (up to $10.50), GET /v1/surveillance/creer
    (up to $50.00), GET /v1/surveillance/:jeton/renouveler (up to $50.00) can exceed it at full size — each of those
    skills says so. No account, no API key. Free text is not interpreted.'

  grade_basis: capabilities is an OBJECT (streaming, pushNotifications, extensions[]); protocolVersion is present
    at the top level ('0.3'); skills is an ARRAY of 116 fully-populated skills. All three optional discriminators
    (preferredTransport, defaultInputModes, defaultOutputModes) are present, and the card additionally carries the
    1.0-shaped supportedInterfaces[]. No hard check fails.
  deviations:
  - field: protocolVersion
    observed: '''0.3'' at the top level while the SDK example and the A2A-Version header say 1.0'
    note: The card keeps the 0.3-era top-level triple (url/preferredTransport/protocolVersion) AND declares supportedInterfaces[];
      a 1.0 reader will use the latter, a 0.3 reader the former. Dual-shaped rather than out of spec.
  - field: capabilities.extensions[0]
    observed: https://github.com/google-a2a/a2a-x402/v0.1
    note: 'Every skill is a PAID resource: a first SendMessage returns an input-required task carrying an x402 quote
      in status.message.metadata["x402.payment.required"]; the signed PaymentPayload goes back on the same task.
      An agent without an x402-capable wallet (or an srn_live_ API key) cannot complete any skill.'
  - field: securitySchemes
    observed: absent
    note: No card-level security scheme; access is payment (x402) rather than authentication. The API-key alternative
      (X-Api-Key srn_live_) is documented in the OpenAPI, not in the card.
  - field: skills
    observed: 116 skills whose ids are OpenAPI path templates
    note: The A2A surface is a 1:1 projection of the paid REST routes (116 of the 125 OpenAPI operations; the 9
      free/utility routes are not skills).
surface_relationship:
  note: Sirenic publishes REST (125 GET operations at https://api.sirenic.eu, OpenAPI at /openapi.json), a remote
    MCP server (POST https://api.sirenic.eu/mcp, streamable HTTP, manifest at /.well-known/mcp.json; OAuth connector
    variant at /mcp/connecteur) and this A2A agent (POST https://api.sirenic.eu/a2a). All three are projections
    of the same 116 paid routes and share the x402 / API-key payment rails; the api-catalog (RFC 9727) links every
    one of them.
