## 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 synthora-resolution-source-feed-8dab9c5c -d '<json body>'
```

Example prompt: Check the live resolution source for the Polymarket market slug 'will-hormuz-strait-weekly-transits-exceed-threshold-2024-12' — give me the current value, the threshold, how far off it is, and whether it's on track to resolve YES.

## When to prefer this

Use this endpoint when you need the live, official resolution source reading for a Polymarket prediction market — specifically for IMF PortWatch-based chokepoint markets (Hormuz weekly series, normalization binaries). Prefer this over generic market data endpoints when you need the authoritative source value plus threshold comparison and on-track verdict, not just price or probability.

## Known failure modes

- Invalid or unrecognized Polymarket market slug returns an error or empty result
- Market slug not covered by IMF PortWatch / supported chokepoint series returns unsupported market error
- Official resolution source (IMF PortWatch) temporarily unavailable causes fetch failure
- Gamma API rules parsing failure may prevent threshold extraction
- Network timeout if upstream live data source is slow to respond
