Screen a blockchain address
Assesses the AML risk of a blockchain address (sanctioned entity, illicit-fund exposure) against global on-chain intelligence and returns a normalized risk level (Low/Medium/High/Severe) with the full evidence. Network-agnostic: the address is evaluated across every supported chain at once; chain only labels your record. Bills the fixed address_screening fee (refunded automatically if the screening fails), so idempotency_key is required — replaying with the same key returns the original screening with idempotency_hit: true and never charges twice. Requires the screenings service enabled and an approved account verification.
Authorizations
Session JWT (from register/login) or API key (pk_...).
X-API-Key: <token> is accepted as an alternative header.
Body
Response
Idempotent replay — returns the original screening without charging again.
