## 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-78b803f8 -d '<json body>'
```

Example prompt: Can you pull the on-chain report acknowledgements for tokenized property with token ID 42 from the LiquProp indexer?

## When to prefer this

Use this endpoint when you need to verify or audit that periodic property reports for a tokenized real estate asset have been acknowledged on-chain via the LiquProp protocol. Prefer this over generic blockchain explorers when you need structured, indexed acknowledgement data tied to a specific property token without paying Polygon gas fees.

## Known failure modes

- Invalid or non-existent tokenId returns empty results or 404
- Indexer lag may mean recent acknowledgements are not yet reflected
- Payment failure (insufficient USDC) results in 402 response blocking access
- Network issues with Polygon may cause stale or incomplete index data
- Malformed tokenId format causes 400 bad request error
