## 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 token-intel-agentdiet-dev-polymarket-live-prediction-market-odds-3d1dfc4a
```

Example prompt: What are the current Polymarket odds and implied Yes/No probability for Bitcoin reaching $150k this year — I want to see the live orderbook sentiment and any whale activity around that market.

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's live orderbooks for macro, crypto, political, or AI events — especially when you want market-implied odds (not sentiment analysis or news summaries) and whale activity signals. Prefer this over social sentiment APIs when you need quantified probability percentages backed by real money bets.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null results
- Ambiguous topic string matches multiple markets — may return incorrect or blended data
- Polymarket API downstream outage causes stale or unavailable data
- Payment failure via x402 protocol prevents request from completing
- Rate limiting or quota exhaustion returns error response
