A purchased prospect list ages the moment it is exported. Built on the official registry, it is fresh by definition. /v1/prospection filters the whole registry — 29,922,486 company numbers, 16,638,954 active — and returns 100 active companies per page, one payment per page.

Pricing is per page of 100 companies. A well-filtered list therefore costs a few cents; a badly filtered one costs the price of pagination. Tighten the criteria before paging.
/v1/recherche is the cheapest route in the catalogue. It returns the top 10 matches with identity, company number, activity code, town, active-or-ceased status, and a confidence score from 0 to 1 that disambiguates namesakes. It is the entry point to use before any more expensive call.
If your need is only to resolve a name to an identifier, be aware that a free public API does that too — we say so on our dedicated comparison page. Paying makes sense once you chain into the data that API does not serve.
/v1/dirigeant/recherche does the reverse: from a surname, it lists the French companies where a person of that name holds or held an office, with the company number, name and role. Useful to map a network, or to look into a director before entering a relationship.
Results are indicative: namesakes are not disambiguated and very common surnames are capped. Person data is limited to surname, first names, role and birth year — in line with the rules applying to registry data. Do not base a decision on a name match alone.
No e-mail addresses, no phone numbers, no named contacts. This is not a coverage gap: that data is not in the official registries, it is collected elsewhere, and reselling it raises lawfulness questions we do not want to carry. Our list gives you qualified companies; making contact stays your job.
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.

claude mcp add --transport http sirenic https://api.sirenic.eu/mcp| Route | Price | What it returns |
|---|---|---|
/v1/prospection (free sample) | $0.02 | French B2B prospecting and lead generation over the full official French company registry (29.8M companies): build targeted company lists with multi-criteria filters — NAF/APE activity code, departement or postal-code prefix, legal form, workforce bracket, company age, active RGE environmental certification, gender-equality index. Returns 100 active companies per page; each page is one payment. Combine filters to narrow a market segment into fresh, registry-grade company lists for France. |
/v1/recherche (free sample) | $0.001 | French company search and company lookup by name or SIREN in the official French company registry (INSEE Sirene / INPI RNE open data). Name search returns the top 10 matches with identity, SIREN, NAF code, city and active/ceased status, plus a score_confiance (0-1 match confidence) that helps disambiguate homonyms. The entry point to official data and company data on France: resolve a trading name to its SIREN identifier before pulling the full company profile, filings or financials. |
/v1/dirigeant/recherche (free sample) | $0.02 | 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. |
/v1/secteur/{code_naf}/benchmarks (free sample) | $0.05 | Sector benchmarks and sector statistics for a French NAF activity code (any level: division, groupe, classe, sous-classe): number of active companies, median company age (with quartiles), workforce-bracket distribution, and — when at least 5 companies file public accounts — median revenue, EBITDA margin, pre-tax result and debt ratio. Peer comparison in one call: place a company against its peers. Aggregates only, no personal data; sectors with fewer than 5 companies are excluded. |
Director search returns indicative results: namesakes are not disambiguated and very common surnames are capped.
No, prospecting returns active companies only. For historical work, use the search route, which returns the status.
Technically yes, by paging, and each page is a payment. Look at the sector statistics first: they will tell you how many companies it contains, and therefore what the export would cost, before you start.
No account to create, no key to request: the first step is free and shows you exactly what you would be buying.
