Compare 2 to 5 companies

This route's particularity is what it refuses to do: it never names an overall winner, because a single rating would hide a weighting that belongs to you alone. And its comparability block tells you when the table you were about to show would have been misleading.

What the route returns

Catalogue description, exactly as agents read it:

Company comparison: compare 2 to 5 French companies side by side in one call on official company data — identity, deterministic default-risk score, latest filed accounts (statutory scope) and BODACC insolvency alerts. Benchmarking for supplier selection and vendor shortlist: per-axis rankings, never an overall winner, plus a comparabilite block that flags NOT comparable companies (different sectors, sizes, a holding in the batch). Billed PER COMPANY: signed quote = $0.12 x number of SIREN.

Expected identifier

sirens parameter: 2 to 5 company numbers, comma-separated.

A wrongly formatted identifier 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.

Price and billing

Price: $0.12 / entité. 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.

Batch billing: the sirens parameter accepts 2 to 5 comma-separated values, and the amount is the unit price times the number of values. The quote is frozen before settlement: there is no partial settlement.

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.

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.

Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.

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.
