## 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 x402-audit-agentdiet-dev-polymarket-live-prediction-market-odds-63451290 -d '<json body>'
```

Example prompt: What are the current Polymarket odds and implied probabilities for Bitcoin reaching $150k this year — include the trading volume and whale sentiment if available.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events from Polymarket specifically — particularly when you want orderbook-level data, whale sentiment, and implied Yes/No probabilities rather than just news or analyst opinion. Prefer this over general news search when quantified market consensus is needed.

## Known failure modes

- Topic keyword matches no active Polymarket markets — returns empty or no-match result
- Polymarket API downstream outage causes stale or unavailable data
- Ambiguous topic keyword returns multiple unrelated markets requiring disambiguation
- Payment failure via x402 protocol results in 402 response before data is returned
- Rate limiting or abuse detection may block repeated identical queries
