## 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-event-details-by-slug-4e755685
```

Example prompt: Pull the full Polymarket event details for the slug 'will-democrats-win-the-2026-midterms' — I want all the sub-markets, their current odds, total volume, and liquidity.

## When to prefer this

Use this endpoint when you need comprehensive details about a specific Polymarket event — including all sub-markets and their current odds — and you already have or can obtain the event's slug. Prefer this over search endpoints when you know the exact event you want.

## Known failure modes

- Invalid or misspelled slug returns 404 or empty result
- Slug from search results may not match current Polymarket event slugs
- Network or upstream Polymarket API downtime causes 5xx errors
- Payment failure via x402 prevents request from completing
- Event may have expired or been resolved, returning stale or empty odds
