## 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 liquprop-api-b9f03873 -d '<json body>'
```

Example prompt: Can you pull up all the blockchain transactions for property ID 'prop-8821' on LiquProp so I can review its on-chain history?

## When to prefer this

Use this endpoint when you need to audit or review the on-chain transaction history for a specific tokenized real estate property on the Polygon network via the LiquProp platform. Prefer this over generic blockchain explorers when you need structured, property-scoped transaction data without manually querying raw chain data.

## Known failure modes

- Property ID not found — 404 response if the specified property does not exist
- Invalid or malformed property ID — 400 bad request
- Payment not provided or insufficient — 402 Payment Required (x402 protocol)
- No transactions found — empty list returned for properties with no on-chain activity
- Authorization failure — 401 if access credentials are invalid
- Relay service unavailable — 503 if the RelAI relay is down
