Public contracts won by a company

What the route returns

Catalogue description, exactly as agents read it:

Government contracts won by a French company, from the official DECP open data: buyers, dates, procedures, estimated end date, lot number, joint holders, CCAG, price type, advance, amendments, declared subcontracting. Each amount is per contract or LOT, excl. VAT, over its full duration, flagged firm price or ENVELOPE (call-offs, framework ceiling — 43% of rows). Totals as two bounds: raw, and deduplicated when one award is published twice. Awarded contracts, not open calls.

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: $0.01. 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.
