## 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 x402-multi-tool-api-stock-quote-113fae11 -d '<json body>'
```

Example prompt: What's the current stock price of AAPL — including today's change and whether the market is open right now?

## When to prefer this

Choose this endpoint when you need a quick, no-auth stock quote for any major US-listed ticker and are already set up for x402 micropayments. At $0.005 USDC per call it is cost-effective for occasional lookups or agent workflows that need on-demand price checks without maintaining API keys for a dedicated financial data provider.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Market closed state may affect availability of real-time prices vs delayed quotes
- Payment failure via x402 (insufficient USDC balance or facilitator issue) blocks the request
- Network timeout on the upstream data provider returns a 5xx error
- Missing required 'symbol' field in request body returns a 400 validation error
