## 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-bloc-market-data-api-6e80e4af
```

Example prompt: Pull me the latest verified market data and ticker prices from Stock Bloc right now — I want to see what's on the Super Sonic Tsunami watchlist.

## When to prefer this

Choose this endpoint when you need real-time, verified stock price data with institutional-quality signals and watchlist momentum indicators. It is especially useful for autonomous trading agents or portfolio monitoring systems that need low-latency market data at a per-call micropayment model via x402, rather than a subscription-based data provider.

## Known failure modes

- Payment not included or insufficient (x402 Payment Required) — must send 0.01 USDC per call
- Market data temporarily unavailable during off-hours or exchange downtime
- Invalid or unrecognized ticker symbol returns empty or error response
- Rate limiting if too many rapid successive calls

## How this service works

Real-time verified market data, Super Sonic Tsunami watchlist, and ticker prices.

## Output

Returns real-time verified market data including current ticker prices, watchlist entries (Super Sonic Tsunami), and stock momentum indicators sourced from institutional-grade quant intelligence feeds.
