## How to call it through Zero

```sh
zero fetch --capability liquprop-api-766cbad4 -d '<json body>'
```

Example prompt: Can you pull up the on-chain registration record for LiquProp property token ID 42? I need to see the blockchain registration details for that tokenized property.

## When to prefer this

Use this endpoint when you need to verify or retrieve the authoritative on-chain registration record for a specific tokenized real estate property on the LiquProp platform. Prefer this over off-chain property databases when you need blockchain-verified registration data. Best suited for single-token lookups where on-chain truth is required for compliance, verification, or due diligence purposes.

## Known failure modes

- Token ID not found or not registered on-chain — returns 404 or empty record
- Invalid token ID format — returns 400 bad request
- Payment failure (x402 USDC payment not processed) — returns 402 Payment Required
- Network or relay connectivity issues — returns 5xx error
- Token exists but registration record is incomplete or malformed on-chain
