## 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-5f3ff534
```

Example prompt: Show me all the canonical prediction market containers available, including their cross-venue Predexon IDs, so I can see what questions are currently listed.

## When to prefer this

Use this endpoint when you need a comprehensive index of available prediction market containers with their canonical cross-venue Predexon IDs, especially when building integrations that need to reference markets across multiple prediction market venues (e.g., Polymarket and others) using a unified identifier.

## Known failure modes

- No markets returned if the index is empty or the service is unavailable
- HTTP 402 Payment Required if USDC micropayment is not attached
- HTTP 500 if the backend market index service is down
- Empty data object if no markets are currently indexed
