HTTP Status Codes

HTTP Status Codes are the fast summary numbers returned with every HTTP response. In Brevvie Python + AI — Section 4: APIs, Postman & Calling the Web, they are taught as the first debugging signal to inspect.

Common examples from the source

200 = success
201 = created
204 = success with no body
400 = bad request
401 = unauthorized / bad or missing key
404 = not found
429 = rate limited
5xx = server-side failure

Why it matters

The section links status-code reading directly to good exception handling and faster API debugging.
