Developers can obtain a JWT (token) using the same OIDC mechanism as our user portal: Obtaining business authorisation from an appropriate Identity Provider service.

With this token, our REST API provides the ability to do anything that can be done through the portal.

Fair Use Policy

Companybook is a free service and is engineered to scale. However, we do reserve the right to block traffic that we think might have a negative impact on performance.

API users are requested to stay within the following limits:

  • full text search: 1 request/second
  • insert/updates: 5 requests/second
  • direct lookups: 10 requests/second

Contact support if you need to go beyond these limits. We may grant exeptional use permission, or you may be a candidate for enterprise support (including dedicated private infrsstructure with arbitrary capacity).
