## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sirenic-french-public-contract-expiration-forecast-211fac71
```

Example prompt: Show me all construction contracts (CPV prefix 45) in department 69 that are expiring in the next 9 months — I want to anticipate re-tenders before they get published, page 1.

## When to prefer this

Choose this endpoint when you need to anticipate French public procurement opportunities before notices are officially published — i.e., proactive pipeline building based on contract expiration forecasting. It is superior to reactive tender-alert services because it surfaces re-tender likelihood 4–9 months ahead of publication. Prefer it over generic tender databases when you want to target specific CPV segments or geographic departments and need incumbent and buyer identity data to guide business development outreach.

## Known failure modes

- Invalid CPV prefix (non-numeric or >8 digits) returns a 400 error
- Department code not matching French format (2-3 digits, 2A, 2B) returns a 400 error
- fenetre_mois outside 1-24 range returns a 400 validation error
- Page beyond available results returns an empty contracts array
- Payment failure (x402) returns a 402 status if USDC payment is not completed
- DECP upstream data lag may mean recently awarded or modified contracts are not yet reflected

## How this service works

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.

## Output

A paginated list (50 per page) of French public contracts approaching their estimated end date, including buyer name, incumbent contractor(s), contract amounts, CPV codes, department, estimated expiration date, and a framework-agreement flag. Sorted by end date ascending within the requested forward window.
