Speed

We guarentee a 200ms average Forecast API response time for Advanced/Enterprise users. (This refers to Server response time. Total request time is dependent on User’s internet connection, and bandwidth.)

Gentle Quotas

Our API’s will gradually degrade as you exceed your rate cap by queueing your requests (slowing reponse times).

*NOTE: Our gentle quotas allow you to burst up to 10% over your minutely rate quota (Advanced or higher plans only)
