## 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-quote-api-2fde3776
```

Example prompt: What's the current price and Stock Bloc score for NVDA right now — is it a buy, sell, or accumulate?

## When to prefer this

Choose this endpoint when you need real-time stock price quotes combined with Stock Bloc's proprietary sbScore and directional action signals (ACCUMULATE, etc.) in a single call. Prefer this over generic market data APIs when the user wants opinionated, scored equity intelligence rather than raw price data alone. Best for AI agents that need to make or recommend trading decisions based on quantitative momentum scoring.

## Known failure modes

- Invalid or unsupported ticker symbol returns empty watchlist or error status
- Payment failure due to insufficient USDC balance blocks request
- Stale data if market is closed — updated_at timestamp will reflect last market session
- Rate limiting if too many calls made in short succession
- Network timeout if upstream market data provider is unavailable

## How this service works

Financial research API for AI agents: Stock Bloc SEC Analyst (10-K/10-Q/8-K filing analysis), market data, MCP tools, and x402 USDC payments on Base.

## Output

Returns a JSON object containing a market feed watchlist array with each ticker's current price, percent change, proprietary sbScore (0-100), action recommendation (e.g. ACCUMULATE), and symbol, along with feed status, update timestamp, and total asset count.
