HTTP 429 Too Many Requests

You are being rate limited. The response should carry Retry-After, and usually X-RateLimit-Limit, -Remaining and -Reset.

Why you would test it

Test that your client backs off on Retry-After rather than retrying immediately — an aggressive retry on a 429 is how a slowdown becomes an outage.
