AML (Anti-Money Laundering) risk checks for addresses and transactions.

Actions: • verify-address: Check if a blockchain address is flagged or associated with fraud, sanctions, ransomware, exploits, darknet markets, or other AML risk categories. Returns risk score, risk band, and the flagging sources. • screen-transaction: Screen a transaction against AML data. Returns whether the transaction is flagged, its risk score/band, and the flagged participant addresses with their roles, scores, severities and categories.

Note: the credit cost of these endpoints is significant — see credits below.

Credits by action (source: OpenAPI): • screen-transaction: 500000 • verify-address: 200000

Credits are indicative only and may change at any time. The actual credits spent for each API request are returned in the response headers.

CryptoAPIs reference documentation — no API call, no credits consumed.

Actions: • blockchains — Supported blockchains, networks, products per chain, denominations, fiat currencies • errors — Complete error code table (HTTP status, error code, message) • credits — Credit charging structure, cost multipliers per blockchain, monitoring & operations taxes (xPub, synced addresses, blockchain events), pay-as-you-go • callbacks — Webhook mechanics: URL requirements, retry strategy (5 retries, exponential backoff), HMAC security, idempotency • limits — Throughput soft/hard limits per plan, 2.1x penalty multiplier, rate limiting behavior
