Single discount badges use the smaller input/output saving, rounded down. Quotes older than 24 hours do not generate discount claims. Sources are checked every four hours; availability and model identity are not independently guaranteed.
Successful API requests are billed at the displayed token rates, metered to a fraction of a cent. Charges accumulate and are deducted from your prepaid balance in whole US cents, so a small request is not rounded up to a minimum charge.

Before production use
- Fetch machine-readable pricing before large jobs because upstream rates can change.
- Check observed status and the disclosed measurement limits.
- Do not submit highly sensitive data to a third-party relay without assessing the upstream terms.
