Read-only price quote for the authenticated customer — base price, subscriber discount,
wallet balance, and can_pay, all in the wallet currency. Lets the app render the paywall
without uploading a scan first. body_scan uses the separately configured body price and covers all selected areas in a combined scan. Combined scan 402 responses include payable items and aggregate totals; credits cover face first. Prices are configured in admin Pay-Per-Use Pricing in USD and converted to the wallet currency.
With service_type=face_scan&include_body=true, returns the combined face-and-body payment
confirmation before capture or validation. Credits cover the face first: zero credits quote
face and body, one credit quotes body only. paywall is null when two credits, unlimited scans,
or the current enforcement rules cover the family. This request does not capture images,
create a scan, reserve credits, or charge the wallet; admission and settlement recheck eligibility.
Without the flag (or when false), the existing single-service quote is returned.
