# Errors and limits

> Handle API errors and request limits.

Errors use a JSON response with an `error` field.

```json theme={null}
{
  "error": "Invalid API key"
}
```

## Request limits

The API allows 100 requests per minute for each workspace. A request over the limit returns `429`.

## Status codes
