## 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-6b8ec58a
```

Example prompt: Pull up the full event details for the Polymarket event with slug 'will-trump-win-2024-presidential-election' — I want to see the market metadata, outcomes, and current status.

## When to prefer this

Use this endpoint when you need full details on a specific Polymarket prediction market event and already have the event slug. Prefer this over a general market listing endpoint when you need deep metadata on a single event rather than browsing multiple events.

## Known failure modes

- Missing or invalid event_slug returns an error
- Event slug does not exist on Polymarket returns a 404 or empty result
- Polymarket API unavailability causes upstream failure
- Malformed slug with special characters may cause a request error

## How this service works

Pay for the outcome. One endpoint for every model, tool and data source an agent needs — each call priced before it runs, at the best value per dollar. 103 models and 100 data and tool APIs.

## Output

Detailed metadata for the specified Polymarket event, including event title, description, possible outcomes, market status, resolution criteria, and related market information identified by the event slug.
