## 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 gadgethumans-polymarket-odds-dbb3633a
```

Example prompt: What are the current Polymarket odds on the Fed rate decision — show me the top 3 markets.

## When to prefer this

Use this endpoint when an agent needs real-time prediction market probability data from Polymarket for events in politics, macroeconomics, crypto, or sports. Prefer this over general news or financial data APIs when you want crowd-sourced implied probabilities rather than raw prices or sentiment scores.

## Known failure modes

- No markets found for the queried topic — returns empty results or ok:true with no data
- Query string too vague or misspelled, returning irrelevant markets
- Rate limit or payment failure if x402 payment not processed
- Polymarket API downtime causes upstream fetch failure
- limit parameter out of range (must be 1-10)
