## 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 mesh-agentdiet-dev-polymarket-live-prediction-market-odds-implied-641f450d
```

Example prompt: What are the live Polymarket odds right now on a US recession happening in 2025 — give me the Yes/No implied probabilities and any whale sentiment data?

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events sourced directly from Polymarket's live orderbook. It is preferable over news sentiment or analyst forecasts when you want market-implied probabilities reflecting actual money at risk, and over generic financial APIs when prediction market data specifically is required.

## Known failure modes

- Topic keyword does not match any active Polymarket market — returns empty or null result
- Polymarket API upstream unavailable — may return 5xx or timeout
- Ambiguous topic resolves to multiple markets — response may include multiple or unexpected markets
- Payment failure via x402 protocol — endpoint returns 402 if USDC micropayment not completed
- Rate limiting or quota exceeded — returns 429 error
