## 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 hergert-synthora-polymarket-markets-41e1dd5f -d '<json body>'
```

Example prompt: Can you search Polymarket prediction markets for anything related to the US presidential election and show me what active markets come up?

## When to prefer this

Choose this endpoint when you need to search and filter Polymarket prediction markets by keyword without building your own Polymarket API integration. It handles pagination fusion across multiple result pages and avoids returning noise when no matches exist. Prefer this over direct Polymarket API access when you want a clean, filtered response with payment-per-use billing via x402.

## Known failure modes

- No matching markets found — response explicitly states no matches rather than returning empty array
- Query too vague — may return broad or unintended market matches
- Polymarket data unavailability — upstream data source outage may yield empty results
- Payment failure — x402 payment of 0.05 USDC not processed, request rejected
- Malformed input — non-string or missing input field causes request error

## Output

A JSON object with ok: true, a niche field set to 'polymarket_markets', a result object containing the filtered list of matching Polymarket prediction markets, and a receipt object confirming the payment transaction. If no markets match the query, the response says so explicitly rather than returning empty or noisy results.
