HTTP 203 Non-Authoritative Information vs 429 Too Many Requests

HTTP 203 (Non-Authoritative Information) is a 2xx Success response, while 429 (Too Many Requests) is a 4xx Client Error response. 203 indicates that the response payload has been modified by a transforming proxy from the origin server's 200 response. 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.
