Rate limits define the maximum number of requests that can be made per minute to the API by a user. Limiting the number of requests to Vimeo helps us ensure that the API remains stable for all users.
If a user exceeds the rate limit, they are returned a 429 error and temporarily prevented from making requests for up to a minute. Developers should anticipate this condition and cease making requests to the API when a 429 error is returned.
On rare occasions, if an app consistently exceeds the rate limit we may block the app altogether. Contact us and provide any technical details if this happens to your app or account.
Technical documentation and specific rate limits are available on the Developer Site.
