Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sec-intel-agentdiet-dev-polymarket-live-prediction-market-odds-91ec9db2

Example prompt: What are the live Polymarket odds right now on whether the Fed will cut rates in September — show me the implied Yes and No probabilities and any whale sentiment?

## When to prefer this

Choose this endpoint when you need real-time, crowd-sourced probabilistic forecasts for macro, political, crypto, or AI events sourced directly from Polymarket orderbooks. It is ideal over static news summaries when you want market-implied probability with volume and whale sentiment context rather than editorial opinion. Best for agents that need to ground decisions in live prediction market data.
