## 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-ef9f128f -d '<json body>'
```

Example prompt: What are the live Polymarket odds and implied Yes/No probability for Bitcoin reaching $100k by end of year — and is there any notable whale activity on that market right now?

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market — especially for macro, crypto, geopolitical, or AI events where market-implied odds reflect aggregated trader belief. Prefer this over static news sentiment when you need a quantified probability (e.g. 73% Yes) with volume and whale-activity context rather than qualitative sentiment alone.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Stale or delayed data if Polymarket API is experiencing latency
- Ambiguous topic resolves to multiple markets — response may include multiple market results requiring disambiguation
- Payment failure if x402 USDC balance is insufficient
- Malformed or too-short topic string triggers validation error
