## 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 workflows-agentdiet-dev-polymarket-live-prediction-market-odds-37b4b2c5

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, geopolitical, or AI events from Polymarket's prediction market orderbooks. Prefer it over news sentiment tools when you want market-implied probabilities with volume and whale activity signals, not just opinion or headlines. Ideal for trading bots, research agents, and decision-support tools that need quantified uncertainty for upcoming events.

## Known failure modes

- No matching Polymarket market found for the given topic — returns empty or low-confidence result
- Topic is too ambiguous and matches multiple markets — may return the highest-volume one or an array
- Market is resolved or delisted — data may be stale or absent
- Orderbook data temporarily unavailable due to upstream Polymarket API downtime
- Payment not processed (x402 micropayment failure) — endpoint returns 402 error
