# rate_limited

> Noptcha API error rate_limited (HTTP 429): what it means and what to do.

Source: https://noptcha.com/docs/errors/rate_limited/

HTTP **429**, `application/problem+json`. When: over a rate limit, or IP blocked after invalid keys.

## What to do

Too many requests: over the create rate of the key, polling one task too often, the sandbox rate, or the client IP is blocked after invalid keys (`detail` says which). Wait for `Retry-After` seconds before retrying. See [Rate limits](https://noptcha.com/docs/limits.md).

See all codes on [Errors](https://noptcha.com/docs/errors.md). Include the `request_id` when you contact support.
