Is there a rate limit on the Flatfile API?

Last updated: December 12, 2025

Flatfile does have a rate limit on the API for the latest version of the Flatfile Platform:

  1. One IP address (regardless of url) making more than 20 requests/second, evaluated over a 10 second window. Practically speaking, this means if you make 400 requests in 8 seconds, that's fine, but if you make 400 requests over 12 seconds you'll exceed the window and get rate limited.

  2. The same request (regardless of IP address) being made more than 20 requests/second, evaluated over a 10 second window. Same rules apply as above.
