Errors and limits

What the different responses mean and how fast you can send requests.

If something is not right, the API replies with a status code and a short message telling you what happened.

CodeMeaning
200 / 201 / 202Success — your request worked.
400Something in your request was missing or wrong.
401Your API key is missing or invalid.
402Your workspace is out of credits — top up to continue.
403Confirm your account email before running checks.
404We could not find what you asked for (for example, a job).
409Not ready yet, or the job is in the wrong state for that action.
413Your request was too big — send a link to a CSV file instead.
429Too many requests too quickly — slow down and retry.
500Something went wrong on our side — try again shortly.

Rate limit

By default you can send up to 1,000 requests per minute. This limit is shared across your whole workspace, not per key. Need more? Get in touch and we will raise it.

Tip

If you hit the limit (a 429 response), wait a moment and try again. Spacing your requests out evenly is the easiest way to stay under it.
