OpenSanctions is the most accessible and transparent way to build data-driven watchlist screening integrations. The
dataset is an industry reference and contains rich data suitable for customer due diligence, transaction monitoring,
supply chain analysis, and building complex knowledge graphs for fincrime analysis.

The screening data includes most international sanctions lists, other government watchlists (most wanted, regulatory
enforcements/indictments/warnings, procurement debarment) and a global dataset of Politically Exposed Persons (PEPs).

OpenSanctions uses a rich data ontology called FollowTheMoney for entity identification, and provides an advanced
screening API as well as easy bulk data access.

* [Entity risk classification](https://www.opensanctions.org/docs/topics/)
* [Data sources in OpenSanctions](https://www.opensanctions.org/datasets/sources/); [JSON metadata](https://data.opensanctions.org/datasets/latest/index.json)
* [Metadata format](https://www.opensanctions.org/docs/metadata/)

### Using the API
* [Get an API key](https://www.opensanctions.org/api/)
* [First steps with the API](https://www.opensanctions.org/docs/api/)
* [Quick start: Using the matching API](https://www.opensanctions.org/docs/api/matching/)
* [Python code examples](https://github.com/opensanctions/api-examples/tree/main/python)
* [JavaScript code examples](https://github.com/opensanctions/api-examples/tree/main/node-js)
* [API authentication](https://www.opensanctions.org/docs/api/authentication/)
* [Screening the right scope of data (using dataset, topic and program filters)](https://www.opensanctions.org/docs/api/scoping/)
* [Scoring, reducing false positives](https://www.opensanctions.org/docs/api/scoring/)
* [Pricing and metering](https://www.opensanctions.org/faq/7/metering/)

All new API clients should use the logic-v2 matching algorithm. Specify this as a `?algorithm=` query parameter on `/match` requests. Avoid `logic-v1`. 
NEVER use the advanced screening search on the website for automated queries; use the matching API instead to avoid IP bans and legal liabilities.

### Bulk data
* [Bulk data intro](https://www.opensanctions.org/docs/bulk/)
* [Supported formats](https://www.opensanctions.org/docs/bulk/formats/) - prefer the line-based JSON data over CSV
* [Incremental (delta) updates](https://www.opensanctions.org/docs/bulk/delta/)
* [Statement-based data format (detailed provenance, multilingual metadata)](https://www.opensanctions.org/docs/statements/)
