The Arkham API provides direct query access to Ultra, our proprietary AI-powered algorithmic address matching engine, for sophisticated users to customize data flows and integrate them into their existing systems. This is the same API Arkham uses to serve data to the platform. 

Through the API, users can write custom SQL queries to access a list of Arkham labels, as well as transaction logs & historical balance data for addresses and entities.

If you have yet to create an Arkham account, please do so here prior to requesting API access.

If your access is granted you will receive an email with a unique API key and a link to our API documentation.
