Rate Limit Exceeded

When a single user makes too many requests to Frontier in a one hour time frame, Frontier returns a rate_limit_exceeded error. By default, Frontier allows 3600 requests per hour – an average of one request per second.

If you are encountering this error, please reduce your request speed. Here are some strategies for doing so:

  • For collection endpoints, try specifying larger page sizes.
  • Try streaming responses to watch for new data instead of pulling data every time.
  • Cache immutable data, such as transaction details, locally

See the Rate Limiting Guide for more info.


As with all errors Frontier returns, rate_limit_exceeded follows the Problem Details for HTTP APIs draft specification guide and thus has the following attributes:

Attribute Type Description
Type URL The identifier for the error. This is a URL that can be visited in the browser.
Title String A short title describing the error.
Status Number An HTTP status code that maps to the error.
Detail String A more detailed description of the error.
Instance String A token that uniquely identifies this request. Allows server administrators to correlate a client report with server log files.
