zero fetch --capability liquprop-api-24ef764e -d '<json body>'
```

Example prompt: Can you pull all the currently registered properties from the LiquProp blockchain indexer on Polygon so I can see what real estate assets are on-chain?

## When to prefer this

Use this endpoint when you need a full enumeration of all on-chain registered real estate properties from the LiquProp platform. Prefer this over individual property lookups when building dashboards, analytics, or needing a complete snapshot of the property registry on Polygon.

## Known failure modes

- Indexer unavailable or syncing — may return empty or partial results
- Network congestion on Polygon causing delayed indexer state
- Payment failure (x402) — call not processed if USDC payment is rejected
- Rate limiting or authentication error if relay credentials are invalid
- Malformed POST body causing 400 Bad Request
