SDKs & Libraries

Official and community SDKs for the Filed API. Currently in development — use the REST API directly in the meantime.

Coming Soon

Official SDKs are in development for Python, Node.js, Go, and Ruby. In the meantime, the REST API works great with any HTTP client.

The API uses standard REST conventions with JSON responses, so integration is straightforward in any language.

Community Libraries

Using the REST API Directly

The Filed API follows REST conventions:

  • Authentication: Bearer token in the Authorization header
  • Format: JSON request and response bodies
  • Pagination: limit + offset for search, page + page_size for federal endpoints
  • Errors: Standard HTTP status codes with JSON error bodies

See the Quick Start guide for examples in curl, Python, Node.js, and Go.
