What the route returns

Catalogue description, exactly as agents read it:

Credit limit for a new French customer: Can I grant Y 20,000 € at 60 days? An indicative amount in euros and terms (comptant, 30_jours, 45_jours) from a published, versioned formula on the class of GET /v1/score/defaillance/{siren} and the workforce bracket, always with the class. Optional montant and delai_jours compare your request. non_evaluable carries its cause, never an amount. Not a credit decision; this legal entity only, group not read.

Expected identifier

9-digit company number of a legal entity; montant and delai_jours, optional, both or neither.

A wrongly formatted identifier in the path returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes. A search parameter, by contrast, is cleaned up: unsupported characters are stripped and the usable query is served.

Price and billing

Price: $0.12. The authoritative amount is the one in the 402 quote returned by the route itself, not this text, which derives from the same grid but is still just a page.

An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

What this route does not do

An indication drawn from public data, not a credit decision. It covers this legal entity only: group exposure is not read. A sole proprietor or a company under restricted diffusion is refused, never billed.

How you pay

Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Open today: 150 free calls a month with an account, on 109 of 126 routes (the price list says which), and pay-per-call over x402 (USDC or EURC), with no account except registry filings. Prepaid credits: card top-up is not open yet.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.

One call, end to end
