## 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-polymarket-odds-movers-17a56941 -d '<json body>'
```

Example prompt: Show me the top 20 Polymarket markets with the biggest odds swings in the last 24 hours, but only include markets with at least $25,000 in daily volume.

## When to prefer this

Use this endpoint when you need a pre-ranked, real-time snapshot of which Polymarket prediction markets are experiencing the most significant price movement over a specific window, rather than querying individual market prices or doing your own sorting. It is ideal for trend detection, alerting workflows, momentum screens, and research digests that need volume-filtered, liquid markets with directional context — all in one structured response.

## Known failure modes

- Invalid window value (not 1h, 24h, or 1wk) may return an error or default behavior
- limit outside 1-50 range may be clamped or rejected
- min_volume set very high may return zero results
- Polymarket data source unavailable causes fetch failure
- Network timeout on the hergertsynthora.com host

## How this service works

Polymarket odds movers: active markets ranked by biggest price swing in the last 1h / 24h / 1wk (window param), with yes price, change and direction, best bid/ask, spread, 24h volume, liquidity and end date.

## Output

A JSON object with an ok flag, the time window used, total markets scanned, a ranked list of up to 50 movers each containing the market slug, question text, yes price, price change, direction (up/down), bid/ask spread, 24h volume in USD, liquidity in USD, and end date — plus aggregate counts of up vs down movers and the single biggest absolute move observed.
