Frequently Asked Questions

Quick answers to common questions about free APIs

What is a public API?
A public API (Application Programming Interface) is a set of endpoints that allows developers to access data or services from a provider. Public APIs are open for anyone to use, often for free, and typically return data in JSON format.
How do I know if an API is safe to use?
Check for HTTPS support (indicated by a green HTTPS badge), review the API's documentation and terms of service, and start with a test request before integrating. APIs with OAuth or API key authentication are generally more trustworthy than those with no auth.
Can I use free APIs in production?
Yes, most free APIs can be used in production, but check each API's terms of service for usage limits, rate restrictions, and commercial use policies. Implement proper error handling and rate limiting in your application.
What's the difference between No Auth, API Key, and OAuth?
No Auth means no authentication is required — just make requests directly. API Key requires you to register and include a key in your requests. OAuth is a more secure flow where users grant your app permission to access their data on another service.
