## 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 company-enrich-agentdiet-dev-polymarket-live-prediction-market-odds-b7e0083c -d '<json body>'
```

Example prompt: What are the live Polymarket odds and implied probability for the US entering a recession in 2025 — including current volume and any whale sentiment?

## When to prefer this

Choose this endpoint when you need real-time, crowd-sourced probability estimates for macro, political, crypto, or AI events as reflected in actual money on Polymarket. It is ideal when you want live market-implied odds rather than LLM-generated guesses, and when you need volume or whale sentiment signals alongside probability. Prefer this over news or sentiment APIs when quantified prediction market probabilities are the goal.

## Known failure modes

- Topic keyword matches no active Polymarket market — returns empty or null result
- Ambiguous topic maps to multiple markets — may return multiple or mismatched results
- Polymarket API or upstream data unavailability causes stale or failed fetch
- Payment not processed (x402 flow fails) — endpoint returns 402 with payment details
- Rate limiting or quota exceeded — returns 429 error
