OpenSanctions
OpenSanctions collects and standardises data on sanctioned entities, politically exposed persons (people in prominent public roles who carry a higher corruption risk), and other risk-relevant subjects, drawing from official sanctions lists and government sources around the world.
Where the same entity appears in both databases, OpenSanctions links to OpenCorporates, so you can build a knowledge graph that combines sanctions and company control information. The free tier is licensed under CC BY-NC 4.0, which permits non-commercial use only. A separate commercial licence is available if you need to build a commercial product.
