### AML Screening

The AML Screening API allows you to screen individuals or companies against global watchlists and high-risk databases. This API provides real-time screening capabilities to detect potential matches and mitigate risks associated with financial fraud and terrorism. You can screen both persons and companies by specifying the `entity_type` parameter.

`POST /v3/aml`

**Estimated cost:** $0.36
