03FAQ
Credits measure how much you use the platform's models. The table above lists what each feature costs. A full-page analysis costs 5 credits. 300 credits cover about 60 analyses. Credits for the current cycle are used first, then your permanent balance. Failed calls and cache hits are refunded to where they came from.
No. During a subscription, credits are granted every 30 days. Anything left at the end of a cycle expires as the next cycle's credits arrive. Your permanent balance isn't affected.
Depends on what you need. With your own key, those tasks don't use credits, but Pro features (like multi-round Agent edits) don't depend on the key and need a subscription. If you only use the free features, you don't need Pro.
No. Every payment is a one-time charge with no auto-renewal. Renew before your plan ends and the new time is added to your current end date.
Full refund within 7 days of purchase if you've used less than 20% of this cycle's included credits. Otherwise, refunds are prorated by the days left.
