Two readings for one call. In prospecting, it is a competitor's commercial track record. In supplier due diligence, it reveals concentration: a provider whose whole revenue comes from a single buyer carries a risk its accounts do not show.

Catalogue description, exactly as agents read it:
Government contracts and public procurement awards won by a French company, from the official DECP open data (données essentielles de la commande publique): buyers, amounts, dates and procedures — aggregates plus the most recent contracts, each with its estimated end date. Covers French public tenders already awarded to the company rather than open calls, a factual view of its government contracts history for supplier due diligence.
9-digit company number.
A wrongly formatted identifier 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.
Dated snapshot from 2026-08-18, truncated to one item per array. It is not live data. The full extract is served free of charge from the samples surface, and the schema from the OpenAPI document.

}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.
