Rate limiting - Descript Help Center

The Descript API implements rate limiting to ensure fair usage and protect service availability. When you exceed the rate limit, the API returns a 429 Too Many Requests response.

Rate Limit Headers

When a rate limit is exceeded, the response includes the following headers:

Header	Description
`Retry-After`	Number of seconds to wait before retrying the request
`X-RateLimit-Remaining`	Number of requests remaining in the current window
`X-RateLimit-Consumed`	Number of requests consumed in the current window

Handling Rate Limits

When you receive a 429 response, use the Retry-After header to determine how long to wait before retrying. This approach is more efficient than using fixed delays or exponential backoff alone.
