Toloka applies the following rate limiting to the requests from clients to the Toloka API.
Toloka limits the number of requests that clients can send per second. If you exceed 300 requests to the Toloka API per second, the platform will return an error with the 429 Too Many Requests HTTP status code. If the problem persists, please lower the number of requests per second and try and repeat your requests in a couple of seconds.
Some of the API methods have their own additional limitations for the methods that allow you to create or edit objects during a minute, hour, or day. Once you reach the limit, the platform will return an error with the 429 Too Many Requests HTTP status code and the reason for the error in the response body.
