Question 1

How do I add an API to the Public APIs directory?

Accepted Answer

You can contribute by submitting a pull request on GitHub with the API details formatted according to the project's guidelines. The README includes a contributing guide with specific steps for adding entries and ensuring they pass automated checks.

Question 2

Public APIs vs RapidAPI: which one should I use?

Accepted Answer

Public APIs is a free, open-source directory focused on listing APIs with basic metadata, ideal for raw discovery. RapidAPI is a commercial platform offering API testing, monetization, and more curated listings—choose Public APIs for cost-effective exploration and RapidAPI for integrated tools and premium services.

Question 3

What's the best free weather API for my app?

Accepted Answer

Public APIs lists several options in the Weather category, such as OpenWeatherMap or WeatherAPI. Compare each for features like forecast accuracy, rate limits, and CORS support by checking their details in the directory before integration.

Question 4

How can I check if an API supports CORS?

Accepted Answer

In the Public APIs table, look for the CORS column—if it says 'Yes' or 'No', it's clear, but 'Unknown' means you may need to test it manually using browser tools or consult the API's official documentation for confirmation.

Question 5

Are all APIs in Public APIs completely free forever?

Accepted Answer

Not necessarily. The directory aims to list free APIs, but providers can change their terms over time. Always verify the current pricing, rate limits, and usage policies on the API's official website before relying on it for long-term projects.

Question 6

How often is the Public APIs list updated?

Accepted Answer

Updates depend on community contributions and automated workflows that validate links, but there's no fixed schedule. While regularly maintained, some entries might become stale, so it's wise to cross-reference with other sources for critical APIs.
