The EU + UK KYB & Sanctions API for Fintech

Prometiam is the company-data and screening layer for B2B fintechs onboarding and monitoring corporate customers across every registry the API covers — one REST API, one bearer token, one schema. It answers the registry and screening legs of KYB: does the company legally exist, who controls it, is any party sanctioned, and has anything changed since onboarding.

Why fintechs pick Prometiam

One key, every registry: every registry the API covers, in the same schema for each country. Officers are held for Spain, France, the UK and Norway; the other countries are company records only.
Beneficial ownership: UK Persons with Significant Control (PSC) in company detail; directors and officers for ES/FR/GB/NO.
Sanctions and US export-control screening (beta) in one call across 6 sources — EU, UN, OFAC, UK OFSI, French Registre des gels, and the US Consolidated Screening List — trigram-fuzzy with confidence scores. PEP screening is beta and Spain-only (no relatives or close associates, so not sufficient on its own for FATF); no adverse-media.
Ongoing monitoring: daily-fresh corporate-event, director-change, and insolvency feeds to catch post-onboarding risk. Company monitoring covers Spain, Ireland, Poland, Finland, Sweden, Belgium, Croatia and Denmark.
Priced for builders: public tiers from EUR 0 (1,000 calls, no card) to EUR 99.99/mo, self-serve, no annual lock-in. Hosted in the EU (Frankfurt).

AMLR readiness

The EU Anti-Money Laundering Regulation applies from 10 July 2027 as one harmonized rulebook. Prometiam covers the registry and screening legs and the ongoing-monitoring obligation — not natural-person identity verification, document checks, or adverse media, which pair with a dedicated identity vendor.
