Rate Limiting

Based on the tier of the user, the API requests are limited.

info

All limits reset at 00:00 each day.

info

The code execution measure does not consider the startup and exit time of the process. Therefore only the code execution time is measured, which roughly equals to ~0.00065s / line.

note

The rate limits are enforced on a per-user basis and reset every minute. If you exceed the rate limit, requests will return a 429 Too Many Requests status code.
