# Rate limits

All backend endpoints are publicly accessible. However, to prevent hitting rate limits quickly, requests **must** include the `x-api-key` header.

API requests are rate-limited per **API key** and **IP address**, covering most standard integration needs. If the request limit is exceeded, the server will respond with an `HTTP`` `**`429 – Too Many Requests`** status code.

If your bot is receiving this error despite staying within the fair limits, or if you wish to request a higher rate limit, please create a [support ticket](https://discord.com/channels/843170059006640179/986580658015076353)
