Frequently Asked Questions & Developer Guide
What is a Zero-Auth API?
Zero-Auth APIs allow developers to make HTTP requests without passing an Authorization header, bearer token, or API key query parameter.
Are there rate limits on keyless APIs?
Yes, providers often enforce IP-based rate limiting to prevent abuse. Specific rate limits are documented on each API detail page.
Can I query them from client-side React / Next.js apps?
Yes. Most endpoints support CORS, and you can also route calls through FreeAPI Smart Edge Gateway for instant CORS handling.
