Prometiam's /sanctions/screen endpoint screens a name against six official sources in one REST call: the EU consolidated list, the UN sanctions list, OFAC SDN, the UK OFSI consolidated list, the French Registre national des gels, and the full US Consolidated Screening List of export-control lists (BIS Entity List, Denied Persons, ITAR debarred, and more) — 44,000+ active entities, refreshed daily. This is sanctions plus US export-control screening; PEP screening is available in beta for Spain only (no relatives or close associates) via ?include_pep=true, and adverse-media is not covered.
Sanctions screening is often implemented poorly: only one list checked, exact-match-only screening that misses transliteration variants, lists refreshed weekly, no confidence scores, no match explanation. Prometiam does the six-source union, the trigram fuzzy match, and the confidence scoring so the integrator just sets a threshold and reads matches.
Full sanctions screening is a Professional-tier scope (€29.99/month, 100,000 calls/month). It is not on the free tier, which includes registry-data scopes only. Standalone vendors like ComplyAdvantage or World-Check start much higher but add full PEP coverage including relatives and close associates, plus adverse-media, which Prometiam does not provide.
