## 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 fold-x402-prediction-market-search-a456d0a2 -d '<json body>'
```

Example prompt: Search fold's prediction market intelligence for up to 10 markets about Fed rate decisions and give me the titles, URLs, and highlights for each.

## When to prefer this

Use this endpoint when an onchain agent or autonomous system needs programmatic, pay-per-use access to prediction market data for a specific topic without requiring an API key or subscription — especially when operating in a crypto-native, x402-payment context and needing structured market intelligence with highlights.

## Known failure modes

- Query returns zero results if topic is too niche or no matching markets exist
- Payment failure via x402 if USDC balance is insufficient (HTTP 402)
- Limit parameter out of range (must be 1-30) causes validation error
- Empty or missing query string may return generic or empty results
- Service unavailability returns non-200 status
