# Inter X

> Inter X is screening intelligence for crypto compliance, payments, and treasury teams. It screens counterparties (Know Your Entity), destination addresses before send (Address Prescreening), and on-chain transactions (Know Your Transaction), plus wallet holdings and USDT blacklist checks.

Self-serve organisation accounts. Authenticate to the HTTP API with an organisation API key (`Authorization: Bearer ix_live_…` or `X-Api-Key`). Base URL: https://theinterx.com/api/v1. Credits are charged for KYT create, address prescreening create, and KYE entity profile; search, history, wallet holdings, and USDT blacklist do not spend credits.

Prefer the markdown and OpenAPI links below over parsing marketing HTML.
