## How to call it through Zero

```sh
zero fetch --capability blockrun-limitless-orderbooks-e4013f50
```

Example prompt: Can you pull the current orderbooks from Limitless prediction markets so I can see the bid and ask levels?

## When to prefer this

Use this endpoint when you need real-time orderbook depth data specifically from the Limitless prediction market platform, accessed via BlockRun's pay-per-call gateway without needing a dedicated API key. Best for agents that already operate in the BlockRun/x402 payment ecosystem on Base or Solana.

## Known failure modes

- Payment not received — 402 response if USDC payment not attached
- No data available — empty data object returned if orderbooks are unavailable
- Gateway error — 5xx if BlockRun upstream is down
- Rate limit or wallet balance insufficient — payment failure
