Rate limiting is a technique employed by APIs to manage the volume and frequency of incoming requests, ensuring a stable and high-quality experience for all users. It helps prevent resource starvation, maintain cost control, and provide a layer of security against potential attacks. To ensure fair usage, prevent system overloading, and protect API resources, our API has rate limits that limit the number of requests that can be made within a specific time frame and request safety. These rate limits differ depending on whether the request is considered safe or unsafe.
It is essential to follow these guidelines to avoid exceeding the API rate limits and receiving HTTP 429 responses. Failure to comply may disrupt your API usage and lower service quality.

Tips

  • To avoid getting blocked or throttled, it is important to adhere to the rate limits that are set. These limits specify the maximum number of requests allowed within a certain period. Please make sure that your application stays within these limits.
  • It’s important to handle rate-limit responses properly. If you receive an HTTP 429 (Too Many Requests) response, the rate limit has been surpassed.
  • Regularly monitor and analyze your application’s rate limit usage to identify potential bottlenecks or excessive usage patterns. This will help you proactively adjust your application’s behavior and optimize resource consumption.

Default rate limits

Default rate limitsBurst allowance*
Safe methods: GET1000 requests per minuten/a
Unsafe methods: POST, PATCH, PUT, DELETE100 requests per minute15 requests per second
*A burst allowance sets the maximum number of concurrent requests the API can handle. It allows for a temporary increase in the request rate to accommodate short periods of high traffic without exceeding the overall rate limits.

​
Non-default rate limits

Some of our API endpoints have rate limits that differ from the default limits, due to their nature or the resources they interact with.
