Searching a director's offices

The search in reverse: you start from the person, not the company. It is the angle that reveals a director accumulating offices in distressed companies — a signal that watching a single company never gives you.

What the route returns

Catalogue description, exactly as agents read it:

Reverse search for company directors and officers in France: a people search by surname (?nom=) that lists the French companies where a person of that name holds or held an office, with each company SIREN, name and the person role — network mapping and due diligence on directors. Person data is limited to surname, first names, role and birth YEAR (French GDPR/INPI rules). Results are indicative: homonyms are not disambiguated and very common names are capped.

Expected identifier

nom parameter: a surname.

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.

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.

What this route does not do

Indicative results: namesakes are not disambiguated and very common surnames are capped. Person data is limited to surname, first names, role and birth year. Do not base a decision on a name match alone.

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.
