## 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 polymarket-market-search-e6f597ac
```

Example prompt: Search Polymarket for markets about the 2024 US presidential election and show me the current yes/no prices for each matching question.

## When to prefer this

Choose this endpoint when you need to search Polymarket specifically by keyword to discover relevant prediction markets and their live outcome prices. Prefer this over Kalshi search endpoints when the user is specifically asking about Polymarket markets. Use this for exploratory discovery of what markets exist on a topic, rather than browsing all markets at once.

## Known failure modes

- No markets found for the given keyword — empty result set returned
- Keyword too broad returns too many markets to be useful
- Market data may be slightly delayed rather than truly real-time
- Service unavailable due to upstream Polymarket API issues
- Payment failure if USDC balance is insufficient for the $0.01 call fee
