## 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 domain-osint-agentdiet-dev-polymarket-live-prediction-market-odds-22aee969 -d '<json body>'
```

Example prompt: What are the live Polymarket odds right now on whether the Fed will cut interest rates at the next FOMC meeting — give me the implied Yes/No probabilities, volume, and what the whales are doing?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events as expressed by actual money on Polymarket. Prefer this over general news search when you want quantified market-consensus odds rather than qualitative opinion, and over historical data sources when you need live, current implied probabilities backed by on-chain trading volume.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null result
- Ambiguous topic matches multiple markets — returns multiple or unexpected market
- Polymarket API unavailable or rate-limited — upstream service error
- Market has low liquidity — probabilities may be unreliable or missing volume data
- Payment of $0.01 USDC via x402 fails — request rejected with 402 status
