Learn API: Make the Request, Understand the Response

Field notes

The curriculum is organized around a repeatable sequence: understand a concept, run an example, and inspect the result. Its practice API exposes predictable task data, while the exercises intentionally introduce cases such as 404, 401, 403, 415, 429, and CORS failures. Separate paths cover Python Requests, JavaScript Fetch, cURL, authentication, pagination, retries, and timeouts, giving the material a concrete workflow rather than a glossary-only treatment.
