## 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-77e63524
```

Example prompt: What are the current live Polymarket odds and implied probability for 'Will the Fed cut interest rates in 2025?' — including volume and whale sentiment?

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from active prediction market participants rather than analyst forecasts or model outputs. It is ideal for macro, crypto, political, and AI events that are actively traded on Polymarket and where implied market odds and whale activity are meaningful signals. Prefer this over news search when you want quantified probability rather than narrative, and over traditional financial data APIs when the event is non-standard (e.g. regulatory decisions, geopolitical events, AI milestones).

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or low-confidence results
- Polymarket API or orderbook data temporarily unavailable — may return stale or error response
- Ambiguous topic keyword matches multiple markets — results may reflect wrong market
- Payment failure via x402 protocol — request blocked if USDC micropayment not processed
- Rate limiting or quota exceeded — endpoint returns 429 or equivalent error
