I'm searching for a book that explains how to effectively use APIs, focusing on making API calls with cURL or wget, particularly for Bash scripts. While I can modify existing examples for a specific API, I often feel lost when starting fresh with a new API. Many resources focus on integrating APIs into applications rather than teaching the fundamentals of API usage. Ideally, I'd like a comprehensive book that covers the basics of using APIs, similar to what would be covered in a dedicated course.

When you're working with HTTP APIs, the key is understanding how to format your requests and knowing the parameters you'll need based on the API's documentation. If you start with the documentation, you can usually find clear examples of what your request should look like. Check out resources like the API documentation for specific services as they often provide practical examples.
It's all about getting comfortable with HTTP requests and reading through the API docs. That's where most of the information lives. Stick to the basics at first, and you'll see patterns emerge that will make new APIs less daunting!
Consider setting up a simple Express app in Node and using a tool like Postman or Bruno to send requests locally. Watching how your API communicates and returns data can be really enlightening and will help the concepts stick!
If you really want a solid reference, I suggest checking out "Everything Curl." It’s a thorough resource that covers a ton of basics, and it should be really helpful for your needs. Don't hesitate to reach out if you want discussion about specific topics!
To simplify your learning process, get a firm grasp of HTTP requests and how response formats work, especially JSON. Each API's documentation usually has good examples showing how to form requests. If you've handled one API well, the transition to others should be easier once you understand the request format.
