KYB & Sanctions API for Crypto & CASPs

Prometiam gives crypto-asset service providers (CASPs) the EU + UK company-data and sanctions layer for MiCA- and AMLR-aligned onboarding. Verify that a business customer or counterparty legally exists in every registry the API covers, and screen it against sanctions and US export-control lists (beta) in one API. Directors and officers are held for Spain, France, the UK and Norway only; every other country is company records only, and beneficial ownership is UK PSC only.

Why CASPs pick Prometiam

Corporate customer verification — confirm legal existence and status of business customers and counterparties in one call.
Sanctions + export-control screening (6 sources, beta) — EU consolidated, UN, OFAC SDN, UK OFSI, the French Registre des gels, plus the US Consolidated Screening List (BIS Entity List, Denied Persons, ITAR); scored fuzzy matching, refreshed daily.
Beneficial ownership — UK PSC beneficial ownership, plus directors and officers for ES/FR/GB/NO.
Ongoing monitoring — watchlist webhooks and daily event/insolvency feeds for the AMLR ongoing-monitoring obligation. Company monitoring covers Spain, Ireland, Poland, Finland, Sweden, Belgium, Croatia and Denmark.
EU data residency — hosted in the EU (Frankfurt) on a GDPR legitimate-interest basis.

Scope and pricing

Prometiam covers the corporate (KYB) and sanctions side only. Retail KYC — natural-person identity verification and travel-rule messaging — is handled by separate vendors alongside it, and PEP screening is beta and Spain-only (no relatives or close associates, so not sufficient on its own for FATF), with no adverse-media screening. No single API makes a CASP MiCA-compliant. Public tiers run from a free plan (1,000 calls, no card) to Professional at €29.99/mo (100,000 calls); most CASPs fit Professional.
