## 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 blockrun-ai-1b025caf
```

Example prompt: Can you pull up the full details for the Polymarket market with slug 'will-trump-win-2024-presidential-election' — I want to see the current odds and market status.

## When to prefer this

Use this endpoint when you need detailed data about a specific known Polymarket prediction market and have the market slug identifier. Prefer this over listing endpoints when you want rich details (odds, resolution criteria, status) for a single market rather than browsing many markets.

## Known failure modes

- Missing market_slug parameter returns 400 or error response
- Invalid or non-existent market_slug returns 404 or empty result
- Polymarket API upstream unavailability causes 502 or timeout
- Payment not processed (x402 payment required) causes 402 response

## How this service works

## Output

Returns detailed metadata about the specified Polymarket prediction market, including the market title, description, outcome options, current probabilities or odds, market status (open/closed/resolved), resolution criteria, and other relevant market attributes.
