Sirenic

Sirenic
● healthy

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 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.

IBANforge

Pre-payout IBAN screening: validation, issuing-bank identification, sanctions (OFAC), Swiss clearing, SEPA + VoP reachability and risk scoring. IBANforge is a tool-style API (REST + MCP), not a conversational A2A agent: integrate via the MCP server at https://api.ibanforge.com/mcp (or `npx -y ibanforge-mcp`), or the REST API described by the OpenAPI document. This card exists so A2A-aware crawlers can index the skills.
