# API Rate Limits - What is the 429 Too Many Requests ?

When you generate documents through `POST https://api.carbone.io/render/:templateID`: ** the maximum number of parallel request is 100 per IP**. 
Above that number, a HTTP status code 429 indicates that too many requests have been sent in parallel. 

The rate limit will involved in the coming months, and it will depends on:
* The duration to generate a document
* The number of parallel requests
* Your Carbone Cloud subscription pricing

This status code prevents abuse by limiting the number of requests users can make in a given timeframe. Developers and users can ensure a smoother experience by implementing strategies like exponential backoff to handle these limits gracefully.
