KYB for crypto and CASPs: KYB and sanctions API

Prometiam gives crypto-asset service providers (CASPs) the multi-country 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, Norway, Poland and the Czech Republic (Polish natural persons are masked by the register itself; Czech natural persons are the name and the month and year of birth only) 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 (the official lists, as at November 2026, beta) — EU consolidated, UN, OFAC SDN, the UK Sanctions List (FCDO), Australia (DFAT), the French Registre des gels, national lists, 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/PL.
Ongoing monitoring — watchlist webhooks and daily event/insolvency feeds for the AMLR ongoing-monitoring obligation. Company monitoring covers every live country except France and Chile.
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 14-day free trial (500 credits, card required, nothing charged for 14 days) to Professional at €29.99/mo (10,000 credits); most CASPs fit Professional.
