  description: 'French & European company data, pay-per-call in USDC or EURC — EURC at numeric parity: the same figure as the USDC price, not FX-converted (at the ECB rate of 4 Sept 2026, about 16 % more in dollar terms) via the x402 protocol — or with an API key and prepaid credits (1 credit = 1 EUR, same per-call prices, no wallet). France in depth plus European search & profiles (BE, CH, UK, NO, EE, LV, CZ, SK, FI, PL), Spanish BORME registry acts (ES, by hoja), Belgian, Finnish and Norwegian annual accounts, and large groups worldwide via LEI/GLEIF. Source: INSEE Sirene / INPI RNE via recherche-entreprises.api.gouv.fr (Etalab 2.0). Payment: x402, network eip155:8453, assets USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 or EURC 0x60a3E35Cc302bFA44Cb288Bc5a4F316Fdb1adb42 (same numeric amount in either). API key: send X-Api-Key: srn_live_… (or Authorization: Bearer srn_live_…) on any /v1 call; the response carries X-Credits-Charged and X-Credits-Remaining. Create an account and keys at
    /compte. A signed x402 payment always takes precedence over a key. Toute réponse non-2xx (400, 402, 404, 5xx) n''est jamais facturée : le paiement x402 est annulé avant règlement — le transfert n''a pas lieu, il n''y a donc rien à rembourser. / Any non-2xx response is never charged: the x402 payment is cancelled before settlement — the transfer never happens, so there is nothing to refund.'
