Rate limiting

This API uses rate controls to limit the requests from clients within a single account to 100 requests per minute. The requests from all clients within the same account are counted together. Exceeding that limit results in a 429 error response. Consider this especially when calling successive operations as part of a loop.

OperationRequests per minute
All operations (default)100
Hostname coverage1

The following response headers provide additional rate limit information:

  • X-Ids-Session-Id: The unique identifier for a rate limit session.

  • X-RateLimit-Limit: 100 per minute except for export and hostname coverage operations.

  • X-RateLimit-Remaining: Number of remaining requests allowed during the current rate limit period.

Once X-RateLimit-Remaining becomes 0, you get a 429 error the next time you make an API call. Wait at least one minute before you call again.
