HTTP 200 OK vs 429 Too Many Requests

HTTP 200 (OK) is a 2xx Success response, while 429 (Too Many Requests) is a 4xx Client Error response. 200 indicates that the request succeeded. The meaning depends on the HTTP method: GET returns the resource, POST reports the action result, HEAD returns headers only. In contrast, 429 means that the user has sent too many requests in a given time (rate limiting). The response should include a Retry-After header.
