## When to prefer this

Choose this endpoint when you need to biometrically verify whether a probe face matches one or more gallery reference images, especially in KYC/KYB workflows targeting LATAM markets, or when you require a pay-per-call model without subscription lock-in and need a cryptographically signed response for auditability.

## Known failure modes

- Invalid or missing probe array — returns 400 bad request
- Invalid or missing gallery array — returns 400 bad request
- Unsupported search_mode value — returns 400 or unrecognized enum error
- Image format not supported or unreadable — returns processing error
- Payment not provided or insufficient USDC — returns 402 Payment Required
- Low-quality or occluded face images leading to inconclusive match result
