## 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-quote-lookup-api-1d7924d2
```

Example prompt: What is the current stock price for Apple — look it up using the symbol AAPL.

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.003/call) real-time stock price lookup by ticker symbol. Ideal for agents that need to spot-check a single equity price, validate a portfolio value, or trigger logic based on current market price. Best suited for simple price retrieval rather than historical data, OHLCV data, or fundamentals.

## Known failure modes

- Invalid or unknown ticker symbol returns an error or empty result
- Missing required 'symbol' query parameter causes a 400-level error
- Market closed periods may return last known price or an error
- Rate limiting or payment failure may result in 402 or 429 status
- Network timeouts from upstream market data provider

## Output
