# Rate Limits We offer two rate limits, **standard** and **premium**. * Standard: 10 requests per second per IP * Premium: 25 requests per second per IP Users on **Free** or **Starter** can utilize the standard rate limit via our default host `api.radiantdrift.com`. Users on **Pro** or **Enterprise** plans can choose between the standard rate limit by sending requests to `api.radiantdrift.com` or the premium rate limit by using `premium.api.radiantdrift.com` instead. Requests to `premium.api.radiantdrift.com` made using API keys without either `pro` or `enterprise` [entitlements](/getting-started/managing-api-keys.md#entitlements) are rejected with a `403 Forbidden` response. ### Rate Limit Enforcement Rate limits are measured over 10 second periods, i.e. for the standard rate limit, you may in fact send 100 requests in 10 seconds. Once the rate limit is exceeded, further requests will receive a `429 Too Many Requests` response for a back off period depending on the applicable limit, as follows: * Standard: 1 minute * Premium: 10 seconds ### Requesting a Higher Rate Limit If your use case warrants a higher rate limit than those posted above, please get in touch to discuss your requirements. We're happy to see if we can support them. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
