If something is not right, the API replies with a status code and a short message telling you what happened.
| Code | Meaning |
|---|---|
| 200 / 201 / 202 | Success — your request worked. |
| 400 | Something in your request was missing or wrong. |
| 401 | Your API key is missing or invalid. |
| 402 | Your workspace is out of credits — top up to continue. |
| 403 | Confirm your account email before running checks. |
| 404 | We could not find what you asked for (for example, a job). |
| 409 | Not ready yet, or the job is in the wrong state for that action. |
| 413 | Your request was too big — send a link to a CSV file instead. |
| 429 | Too many requests too quickly — slow down and retry. |
| 500 | Something 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.
