## 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 stock-pulse-prediction-markets-188c26f8
```

Example prompt: Pull up the top 5 prediction markets for NVDA — I want to see what traders are forecasting for it right now.

## When to prefer this

Use this endpoint when an agent needs to surface crowd-sourced prediction market sentiment tied to a specific US stock ticker (e.g. NVDA, AMD, SPY). Ideal for financial research workflows that want to combine traditional equity data with decentralized prediction market signals. Prefer over generic search when you need ranked-by-volume prediction contracts with optional keyword filtering, and no API key or account is required — just USDC on Base.

## Known failure modes

- Missing required 'ticker' parameter returns a 400 validation error
- Invalid or unrecognized ticker symbol may return empty results
- market_limit out of range (< 1 or > 10) returns a validation error
- Payment not provided or insufficient USDC triggers a 402 Payment Required response
- Network or upstream data source outage may cause 500 errors

## How this service works

One call returns prediction market sentiment (Limitless Exchange) + live equity price for a specified ticker. Collapses the prediction-market → stock-price agent chain into a single x402 payment. $0.016 vs $0.024 bought individually. Inputs: ticker (required), query (optional keyword filter for prediction markets).

## Output

A ranked list of up to 10 prediction market contracts associated with the given stock ticker, ordered by volume, with optional keyword filtering applied. Each result includes market metadata such as title, volume, and relevant contract details.
