## 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

Example prompt: What are the live Polymarket odds and implied Yes/No probabilities right now for 'Will the Fed cut rates in 2025?' — I want to see the orderbook volume and any whale sentiment signals too.

## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates from Polymarket's prediction market, especially for crypto, macro, AI, or geopolitical events. It is preferable over traditional news or sentiment APIs when you want market-implied probabilities backed by real money and volume signals, and when whale positioning or orderbook depth is relevant to your decision.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Topic too vague or ambiguous to resolve a specific market — may return multiple candidates or fail to match
- Market may be resolved or closed — historical data returned instead of live odds
- Rate limit or payment failure via x402 — returns 402 Payment Required if USDC micropayment is not attached
- Polymarket API upstream outage — may return error or stale data
