An honest comparison of Prometiam and Pappers for French and cross-border company data. Pappers is the strongest modern product for France-only work — clean UX, transparent pricing, deep BODACC + INSEE + INPI coverage, plus Pappers Justice for litigation data. If your scope is exclusively French, this page recommends staying with Pappers. Prometiam is the better fit when scope crosses borders or when sanctions screening belongs in the same API.
One REST API covers Spain (BORME), France (BODACC + INSEE), the UK (Companies House), and Norway (Brønnøysundregistrene, companies and directors) daily, plus Ireland (CRO) and Poland (KRS) at company level only — no directors or UBO for those two. The same response shape applies across ?country=ES|FR|GB|IE|PL|NO. Sanctions and US export-control screening spans 6 sources (EU, UN, OFAC, UK OFSI, French gels, and the US Consolidated Screening List / BIS Entity List, Denied Persons, ITAR) — 44,000+ active entities. PEP screening is beta and Spain-only (no relatives or close associates); no adverse-media and no natural-person identity verification.
French judicial-procedure tracking (Pappers Justice), deep INPI trademark data, and French-vendor UX. Prometiam does not replicate these.
Public tiers, monthly or annual (ten months' price for twelve): free — 14-day trial, 1,000 calls/month, no card, subscribing keeps the same key working — then €9.99, €29.99 (sanctions included), €99.99 and Custom. Professional can replace Pappers plus a separate sanctions vendor for most KYB use cases.
The developer choosing between these APIs is usually building a company lookup: resolving a NIF, a SIREN, a company number or a few typed letters into a name, legal form, status and address for an onboarding form, an invoice or a CRM. Every registry's identifier is one parameter — SIREN/SIRET (France), NIF/CIF (Spain), company number (UK), CRO number (Ireland), KRS number (Poland), organisasjonsnummer (Norway) — and ?name= is a normalised partial match a type-ahead field can call on every keystroke, across the same schema for all six countries. Auth is one bearer key; rate limits scale 10 to 600 requests/minute by tier. A TypeScript SDK (prometiam-risk-api on npm) and an MCP server (prometiam-risk-mcp, also at /mcp) are both published. Free SIREN, NIF, Companies House number, KRS, CRO number and organisasjonsnummer lookup tools run the same call without a key.

Two derived signals on the Prometiam side, neither of them a rating: registry_compliance, which marks companies still on the register that stopped meeting their filing duties (Spain, the United Kingdom, Ireland and Norway), and public procurement — contract awards from Spain, France, the UK, Ireland, Poland and Norway by supplier, buyer, identifier, CPV code and date, plus a beta score for the contracting body itself in Spain and France. Both are dated facts with their source, on the published price and in the free tier; a score is a prompt to look, never a finding of wrongdoing. Public-buyer risk · Procurement screening
