429 "Too Many Requests" and other rate-limit errors
A rate-limit error is a protective pause, not a problem with your data. Wait the time it tells you and try again.
429 in the app
You've hit an internal limit on a heavy action, such as generating PDF reports or running vendor scans. These reset on a rolling window (a minute or an hour depending on the action). Wait for the period shown in Retry-After and try again.
429 on the Public API
That API key has exceeded 300 requests in a minute. Back off, then retry after the number of seconds in the Retry-After header. Details in API rate limits.
503 "Rate limiting temporarily unavailable" on the API
A rare hiccup on our side, not something you did. Retry after a short pause. If it continues for more than a few minutes, check status.dmarcs.com or contact support.
