## 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`):

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

## When to prefer this

Use this endpoint when you need real-time, crowd-sourced probability estimates for specific future events — particularly in the crypto, macro, and AI policy domains. Prefer it over news sentiment APIs when you want market-implied probabilities backed by actual money rather than opinion polls. It is especially valuable when you want to understand where large traders ('whales') are positioning and the actual orderbook depth behind the headline odds.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null result
- Polymarket API or orderbook data temporarily unavailable — upstream timeout or connectivity error
- Topic query too vague — multiple markets matched with ambiguous results
- Payment not processed via x402 — request blocked before data is returned
- Rate limiting or quota exceeded — 402 or 429 error returned
