# Company-level collective agreements published on Légifrance

Since 1 September 2017 every company agreement is published on Légifrance. This route finds them by filing SIRET and serves what matters for HR or supplier due diligence: what was negotiated (pay, working time, telework, equality, profit-sharing), when, with whom, under which collective agreement — and whether the agreement declared to Sirene matches.

## What the route returns

Catalogue description, exactly as agents read it:

**Company-level collective agreements of a French company published on Légifrance (ACCO fund, mandatory since 2017-09-01): title, nature (accord, avenant), DILA themes (pay, working time, telework, gender equality, profit-sharing...), signature, effect and end dates, collective-agreement code (IDCC) checked against Sirene, signatory unions and the official link. Metadata only, never the text nor a person's name. Searched by filing SIRET (up to 25 establishments), cached 24h.**

## Expected identifier

9-digit company number of a legal entity; a sole proprietorship answers 400 and is never charged.

> ⚠️ 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.

## Extract from a genuinely paid response

Dated snapshot from 2026-09-13, truncated to one item per array. It is not live data. The full extract is served **free of charge** from [the samples surface](https://api.sirenic.eu/exemples/), and the schema from the OpenAPI document.

## Price and billing

Price: **$0.02**. 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.

## Calling the route

## What this route does not do

Metadata only: **never the text of the agreement nor a signatory's name**. An empty list does not mean no social dialogue (headcount threshold, filing under another SIRET, unpublished decision); nature and effect dates are read only on the twenty most recent texts.

## 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](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) 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](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**
