Rate Limiting

As we open up our API to more and more usage, the rate limits will help make sure our system will remain stable and available to everyone.

Please note, some API queries will require us to fetch the requested url. If the server for the requested url is slow to respond, our results will also be delayed. We allow up to 20 seconds for responses to complete.
