## 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 outcomescout-news-to-markets-329c35e7 -d '<json body>'
```

Example prompt: I just saw a headline that 'Fed signals rate pause in September' — find me the most relevant Polymarket prediction markets I can trade on this right now, ranked by relevance, with live odds and a bet link.

## When to prefer this

Use this endpoint when a trading agent needs to instantly map a breaking news headline to actionable Polymarket prediction markets with live market data. Prefer it over manual Polymarket search when speed matters, when building automated news-to-trade pipelines, or when you need structured market metadata (odds, liquidity, spread) in a single call rather than scraping the Polymarket UI.

## Known failure modes

- No matching markets found for obscure or very recent headlines
- Stale odds if Polymarket data feed is delayed
- Low liquidity markets returned for niche topics
- Ambiguous headlines may surface loosely related markets
- Rate limit or payment failure for the $0.01 USDC per-call fee

## How this service works

Turn a news headline into the matching Polymarket prediction markets to trade. One call returns the top markets ranked by relevance, each with live odds/implied probability, 24h drift, spread, on-book liquidity, volume, resolution date, and a ready bet link. Use when a trading agent reacts to breaking news and needs the tradeable market instantly. $0.01 USDC on Base.

## Output

An ordered list of Polymarket prediction markets ranked by relevance to the input headline, each containing: market title, live odds/implied probability, 24-hour odds drift, bid-ask spread, on-book liquidity, total trading volume, resolution date, and a direct bet link to execute the trade on Polymarket.
