Intelligence brief on a company

This is the most expensive route, and it is justified in one case only: when you would rather make one call than orchestrate ten. Conversely, if you already know which block you care about, the à-la-carte dossier costs a fraction of the price.

What the route returns

Catalogue description, exactly as agents read it:

French company intelligence report for due diligence — ONE call, all blocks cross-referenced: identity, officers with OTHER public offices (network map), financials with multi-year trends, sector benchmarks, failure-risk score, BODACC, sanctions, FR/EU procurement, IP, Seveso/ICPE, AMF, lobbying, Egapro, establishments, INPI filings, live VIES. Closed-list risk signals, rule-based verdict, figures-first executive summary. Ed25519-signed report, provenance per block (official register + as-of).

Expected identifier

9-digit company number.

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: $1.00. 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.

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.
