## 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-372e55f3
```

Example prompt: Can you pull up all the available prediction market listings across every venue on BlockRun right now so I can see what markets are currently executable?

## When to prefer this

Use this endpoint when you need a comprehensive, flattened view of all executable prediction market listings across multiple venues in a single call, rather than querying individual venue APIs separately. Ideal for agents that need to enumerate available markets before executing trades or analyzing market availability on BlockRun.

## Known failure modes

- Empty data object returned if no active listings are available
- HTTP 402 if payment of 0.001 USDC is not included in the request
- HTTP 500 if the upstream market data aggregation fails
- Rate limiting errors if too many requests are made in quick succession
- Partial data if some venue feeds are temporarily unavailable
