OpenSanctions

OpenSanctions is an open database of international sanctions, watchlists, criminal designations and politically exposed persons (PEPs), published as a screening API, bulk data downloads and MIT-licensed open-source software from Berlin. It consolidates hundreds of primary government sources — OFAC, the EU consolidated list, UN Security Council, UK FCDO, procurement debarment registers, regulatory enforcements and national PEP registers — into a single de-duplicated entity graph expressed in the FollowTheMoney ontology it stewards. The hosted Screening API at api.opensanctions.org offers query-by-example entity matching with scored, per-feature explanations, free-text search, entity fetch with relationship traversal, statement-level provenance for every asserted value, and an OpenRefine reconciliation manifest. It is used for customer due diligence, transaction monitoring, supply-chain and vessel screening, KYB, and investigative journalism. The dataset is free for non-commercial use under CC BY-NC 4.0; commercial use is licensed, and the API is metered at EUR 0.10 per query.

OpenSanctions publishes 1 API on the APIs.io network: Screening API. Tagged areas include Sanctions Screening, Anti-Money Laundering, Politically Exposed Persons, Compliance, and Financial Crime.

OpenSanctions’ developer surface includes engineering blog, documentation, API reference, getting-started guide, support, pricing, signup flow, and 33 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/opensanctions: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you?
