## 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 llms-generator-agentdiet-dev-polymarket-live-prediction-market-odds-5f74f76d
```

Example prompt: What are the live Polymarket odds and implied Yes/No probability for 'Will the Fed cut rates in 2025?' — and tell me the current volume and what whale sentiment looks like.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket for macro, crypto, political, or AI events — especially when you want orderbook-level detail including Yes/No implied odds, volume, and large-trader (whale) sentiment. Prefer this over generic news or sentiment APIs when you specifically want prediction-market-priced probability rather than news tone or social media sentiment.

## Known failure modes

- Topic not found on Polymarket — no active market matching the keyword returns empty or null results
- Ambiguous topic keyword matching multiple markets — may return results for unintended market
- Stale or delayed data if Polymarket orderbook is illiquid or market has closed
- Payment failure via x402 protocol resulting in 402 response with no data
- Rate limiting or upstream Polymarket API downtime causing 503 or timeout errors
