Introduction

Introduction to BlockSec AML API

The BlockSec AML API Service offers two main sets of APIs, providing services for address label queries and wallet screening queries, respectively.

Users who subscribed to the API service before May 6th should visit v2 (retired) to access the docs for the previous version of the API. We will continue supporting the old API version until July 1st 2024, so kindly migrate your relevant projects to the new version before that deadline.

The API key remains valid and can be used across both versions.
