429 with an empty body and a Retry-After header in seconds.
Minute windows start on the minute, and day windows at midnight UTC.
Headers
Every answer to a counted call carries the state of the route’s limit with the fewest calls left:See every limit
GET /v1/limits answers every limit with what is left of it, and the calling key’s spend today against its daily cap. It has its own limit, so reading the limits never spends them.
Handling a 429
Wait the seconds inRetry-After, then send the call again. A 429 is never charged. Calls without a valid key are limited by IP address instead of by organization.
