## 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-5ffd4a29
```

Example prompt: What are the live Polymarket odds right now on the Fed cutting interest rates before end of 2025 — give me the Yes/No implied probabilities and any whale sentiment you can find?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from an active prediction market (Polymarket) rather than model-generated forecasts. It is ideal for querying current market sentiment on crypto, macro, AI, or political events where live orderbook-backed implied probabilities and whale activity are more informative than news summaries or analyst opinions. Prefer this over general news search when you want quantified probability estimates with volume and sentiment context.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or null result
- Topic keyword too vague — may return unrelated or multiple ambiguous markets
- Polymarket API unavailable or rate-limited — upstream data fetch failure
- Payment not completed (HTTP 402) — x402 micropayment required before data is returned
- Stale data if Polymarket orderbook has low liquidity or market has resolved
