## 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 x402-polymarket-market-detail-51eaf9df
```

Example prompt: Pull up the full details for the Polymarket market with slug 'will-trump-win-2024-presidential-election' — I want to see the current yes/no prices, volume, liquidity, and whether it's been resolved.

## When to prefer this

Use this endpoint when you need detailed, current market data for a specific known Polymarket market and already have its slug. Prefer the sibling search/list endpoint to discover slugs first if unknown. Choose this over the Kalshi Market Detail endpoint when the market is on Polymarket's decentralized platform specifically.

## Known failure modes

- Invalid or misspelled slug returns an error or empty result
- Market may have been delisted or archived, returning not-found
- Polymarket API upstream downtime causing fetch failure
- Slug format mismatch if user provides URL path instead of bare slug
