OpenSanctions API

Sanctions, PEP & watchlist screening; self-host or non-commercial for free

OpenSanctions consolidates global sanctions lists, politically-exposed-persons (PEP) data, and criminal watchlists into a single open dataset with entity search and bulk name matching (FollowTheMoney model, Reconciliation API support). The data and the 'yente' API server are open source, so you can self-host for free; the hosted SaaS API is free for non-commercial use and metered for commercial use.
