## 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-procurement-competitor-intelligence-by-siren-37cca237
```

Example prompt: Who are the top competitors winning French public contracts in the same market segments as SIREN 130031487? I want to see their contract counts, total amounts won, and which CPV categories we share over the last 3 years.

## When to prefer this

Use this endpoint when you need competitive intelligence specifically for French public procurement markets — i.e., identifying which rival contractors are winning government contracts in the same CPV categories as a target company. Prefer this over generic company comparison endpoints when the focus is on public-sector bidding strategy rather than financial or firmographic comparison.

## Known failure modes

- Invalid or non-existent SIREN returns an error or empty result
- Company has no public contract history, so no CPV segments can be derived and no competitors are returned
- SIREN has fewer than 5 CPV segments, resulting in a narrower comparison scope
- DECP data lag may mean very recent contracts are not reflected
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

Who wins French public contracts on the SAME CPV segments as a given company (SIREN): top rival contractors over the last 3 years, with contract counts, total amounts and shared segments — competitive intelligence for public-procurement bidding, from DECP open data. The company's own top-5 CPV segments (last 5 years) define the comparison scope.

## Output

A ranked list of competitor companies that have won French public contracts in the same top-5 CPV segments as the queried company over the last 3 years, including each competitor's name, SIREN, contract counts, total contract values, and the specific shared CPV segments that define the competitive overlap.
