Example prompt: Can you run a proptech biometric validation check on this access request for tenant John Smith at 245 Park Ave — I need a pass/fail result on whether the biometric credential is valid.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call biometric validation result in the proptech domain, especially when integrating with MCP-native agent workflows that support x402 micropayments on Base L2 and require a simple boolean pass/fail output.

## Known failure modes

- Missing or empty prompt field returns a 422 validation error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Malformed input causes processing failure with no report returned
- Network or node availability issues may result in timeout or 503 errors
- Ambiguous or unsupported biometric prompt may return false negatives
