Free API Catalog is a curated directory of 2000 free APIs across 25 categories, built to help developers discover the right API for their next project.
Why?
Finding good, free APIs shouldn't be hard. There are amazing public APIs out there, but they're scattered across the internet. This catalog brings them together in one searchable, filterable place.
How it works
Each API is rated on reliability, documentation quality, and ease of use. APIs that require no authentication are marked — perfect for prototyping and learning.
