Free results and the bill
2026-05-04 · Billing
Invalid images and low confidence are free. They still take a request. They do not take a credit.
A day with 1,000 requests and 900 reliable answers costs 900 credits. The other 100 were refreshes. The usage chart shows both bars so you can see the ratio.
A sudden jump in free results usually means the crop changed, the options changed, or the portal changed the picture. It is not a billing bug.
Charged results that the portal accepts are the ones to keep. Charged results the portal rejects are candidates for report, inside the cap.
Do not turn retries of reliable results into a habit. Those are paid twice and the text does not change.
