# Rate Limits

A rate limit is the number of API calls an app or user can make within a given time period. If this limit is exceeded or if CPU or total time limits are exceeded, the app or user may be throttled. API requests made by a throttled user or api will fail.

**All API requests are subject to rate limits.**

Above mentioned rate limits are calculated per minutes. 

#### Error Codes <a href="#error-codes" id="error-codes"></a>

When an app or user has reached their rate limit, requests made by that app or user will fill and the API will respond with an error code.

| Status code | Description       |
| ----------- | ----------------- |
| 429         | Too many requests |

#### Response Example

```json
{
    "message": "Too Many Attempts."
}

```
