## 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 romny-polymarket-data-period-settlement-outcomes-a2e1b05c
```

Example prompt: Pull the latest Polymarket settlement outcomes for the past 15 minutes so I can see which multi-asset markets resolved and what the outcomes were.

## When to prefer this

Choose this endpoint when you need near-real-time Polymarket settlement outcome data over a short rolling window (5 or 15 minutes). It is ideal for bots or agents that monitor prediction market resolutions, trigger downstream trades or alerts on settlement events, or audit recent contract closures. Prefer this over the panel snapshot endpoint when you specifically need settled/resolved outcomes rather than the full live market state.

## Known failure modes

- Invalid timeframe value (not '5m' or '15m') results in a validation error
- No settlements in the requested window returns an empty result set
- Payment not provided or insufficient USDC triggers HTTP 402 payment required
- Service downtime or upstream Polymarket data unavailability causes 5xx errors
- Rate limiting may apply if called excessively in short succession
