API restrictions/limitations
Our API is subject to the same terms and conditions as any other usage of is.gd. We don't expect authors to take responsibility for the actions of end-users of their apps, but an application shouldn't appear to endorse or be solely designed to do something that's against our terms.
API users should open a maximum of 5 connections to is.gd at any one time.
Access to our API is rate limited to make sure usage doesn't exceed levels that we consider reasonable. Please see our usage limits page to check the current limits. If your application is exceeding our rate limit and receives an error code 3 response (or an HTTP status code of 502 which is the equivalent when using simple format) it should wait a reasonable period such as 1 minute before making any further requests. Machines that continue to hammer us with requests regardless risk being banned.
