429

A usage limit was reached, or this IP address made too many requests with a wrong key.

Usage limits are per workspace and plan: per minute (Retry-After: 60), per day (Retry-After: 3600), and per month (no Retry-After). They use their own body shape. An IP address may send 10 wrong keys a minute; one more is allowed every 6 seconds. While that allowance is used up, every request from the address is refused, even one with a valid key.
