## 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-lookup-by-slug-0d584fc8 -d '<json body>'
```

Example prompt: Can you look up the Polymarket market for the slug 'will-the-fed-cut-rates-in-2025' and tell me the outcomes, their current prices, and the CLOB token IDs?

## When to prefer this

Use this endpoint when you need to resolve a Polymarket market's slug into its full metadata — especially CLOB token IDs and conditionId — which are required for programmatic trading or market monitoring. Prefer this over scraping Polymarket directly, as it provides structured Gamma data at a low per-call cost via x402.

## Known failure modes

- Invalid or non-existent slug returns an error or empty result
- Market has been resolved or delisted and data may be stale or unavailable
- Payment failure via x402 protocol results in 402 response before data is returned
- Malformed POST body causes validation error
