## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability m2mcent-logistics-biometric-optimizer-mcp-hash-validation-e02895d1 -d '<json body>'
```

Example prompt: Can you validate this hash string — `a3f9c2d8e1b047...` — through the logistics biometric optimizer to see if it returns true or false?

## When to prefer this

Use this endpoint when you need a fast, binary valid/invalid answer for a hash in a logistics or biometric optimization pipeline and are operating within the M2MCent x402 payment network on Base L2.

## Known failure modes

- Missing or malformed hash input returns a validation error
- Hash not found or unrecognized returns false rather than an error
- Network or payment failure (x402) results in no response or HTTP 402
- Empty string hash may cause schema validation rejection
- Service downtime returns 5xx with no boolean result
