Rate Limiting

Description of Spectrum's rate limiting policy

Rate Limit Policy

Effective Date: March 1, 2023

API calls such as aggressive polling or making highly concurrent API calls may result in your app being rate limited. Spectrum's rate limits may vary based on licensing plan purchased. Rate limiting is a strategy for limiting network traffic. It puts a cap on how often someone can repeat an action within a certain timeframe – for instance, trying to access a Spectrum specification. Rate limiting can help stop certain kinds of malicious activity. It can also reduce load on web servers.

API endpoint limits

To ensure the quality of Spectrum's services, most APIs are subject to rate limiting. Depending on the API endpoint, the request limit and the rate limit window in which the request limit resets, may vary.

Exceeding these values triggers an HTTP 403 response. These are in addition to those indicated in the rate limit response headers. If your app triggers the rate limit, please refrain from making additional requests until the appropriate amount of time has elapsed. In general, keeping requests for the same API endpoint under 100 requests in 60 seconds, will not trigger rate limiting.


Please contact your customer service manager to discuss any exceptions needed.
