## 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-2e32def5

## When to prefer this

Choose this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market for macro, crypto, political, or AI events. It is ideal for agents that need live implied odds and whale sentiment rather than analyst forecasts or news sentiment. Prefer this over social media sentiment tools or news APIs when quantified market-based probability is required.

## Known failure modes

- Topic keyword too vague or ambiguous — no matching Polymarket market found
- Polymarket API or orderbook data temporarily unavailable — empty or error response
- Payment failure via x402 — endpoint returns HTTP 402 if USDC micropayment not processed
- Rate limiting or quota exceeded — request throttled
- Topic matches multiple markets — response may include multiple results requiring disambiguation
