Upcoming public-contract expiries

The opposite of an alert on a published notice: buyers typically re-tender 4 to 9 months before expiry, and that is the window this route opens. The framework-agreement flag is the field to read first: an expiring framework agreement is not re-tendered like an ordinary contract.

What the route returns

Catalogue description, exactly as agents read it:

Upcoming French public-contract EXPIRATIONS — the predictive layer over DECP open data: contracts whose estimated end date falls inside your window (fenetre_mois, 1-24 months), filterable by CPV prefix (cpv=45) and department, with buyer, incumbent holders, lot number, declared subcontracting, and amounts flagged firm price or ENVELOPE (call-offs, subsequent contracts, tranches, framework ceiling). Buyers re-tender 4 to 9 months before expiry: anticipation BEFORE publication. 50 per page.

Expected identifier

No identifier: fenetre_mois from 1 to 24, plus optionally a cpv prefix and a department.

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: $0.05. 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

End dates are estimated from the notification date and the declared duration. This is not an official re-tendering calendar, and some upstream rows are incomplete.

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.
