## 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 scrapling-x402-polymarket-lookup-5297ce25
```

Example prompt: Search Polymarket for prediction markets about Bitcoin hitting $100k and tell me the current yes-probability and how much it has moved in the last 24 hours.

## When to prefer this

Use this endpoint when you need to programmatically search Polymarket prediction markets by keyword and retrieve current probability data and recent price movement. It is well-suited for agents that need to monitor sentiment or odds on specific topics without scraping Polymarket directly. Prefer this over manual browsing when keyword-based search and structured JSON output are needed.

## Known failure modes

- No results found if keyword matches no active markets (empty results array)
- Missing or empty 'q' query parameter returns a validation error
- Service may return stale or cached data if Polymarket upstream is unavailable
- Payment failure (402) if x402 payment header is missing or insufficient
- Rate limiting or timeout if the upstream Polymarket data source is slow

## How this service works

Polymarket odds for an event: up to 10 markets matching a keyword with YES probability %, 1h/24h/7d odds change, volume and liquidity. Example: q=bitcoin, q=election, q=fed rate. Refreshed about every 30 min

## Output

Returns a count of matching markets and a list of results, each containing the market question text, the current yes-probability as a percentage, and the 24-hour change in yes-probability in percentage points.
