API Keys

Get your API key here.

Best Practices​

Keep your API key confidential and avoid hardcoding it into your applications source.


The API key is used to register context_ids and get address information of your users.

Include it as an x-api-key header in your request when calling:

  • GET /api/v1/users/eoa
    • These API requests are recorded and billed monthly.
  • POST /api/v1/register/context_id
    • You can make any number of context_id's per API key and incur no cost.


Every client gets the first 1,000 eoa requests for free. After that, billing is required based on the number of requests sent by the client. Pricing is tiered and available upon request.
