Reference

iNaturalist actually provides two APIs:

  • The original, Rails-based REST API that they also use internally: it is very complete and provides read/write access, but is rather slow and sometimes inconsistent.

  • The Node-based API allows read-only access to most iNaturalist resources, is faster and provides more consistent behavior than the REST API, but with fewer features.

Pyinaturalist provides functions to use both of those APIs.
