When to use it

•When you need to find a free API for a specific functionality or data source
•When you want to explore new APIs for prototyping or proof-of-concept development
•When you're looking for alternative APIs to paid services or proprietary solutions

Ready-to-paste prompt

Use the 'https://api.example.com/data' API to fetch data on a specific topic, for example: curl https://api.example.com/data/topics/technology

Heads up: Some APIs listed in the public-apis repository may require API keys, have usage limits, or be deprecated, so it's essential to review the API documentation and terms of use before integrating it into your project
