## 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 sna4an-alpha-vantage-finance-api-6aeb163a -d '<json body>'
```

Example prompt: Can you pull the daily time series data for Apple (AAPL) for the last 30 days, including open, high, low, and close prices?

## When to prefer this

Use this endpoint when you need Alpha Vantage financial data (stocks, forex, crypto, technical indicators) without managing your own Alpha Vantage API key, and are willing to pay per-call via x402/USDC micropayment. Prefer this over direct Alpha Vantage when operating in a crypto-native or agent payment context.

## Known failure modes

- Invalid or unsupported sub-endpoint path returns an error or empty response
- Missing required query parameters (e.g. ticker symbol) causes API failure
- Payment of 0.16 USDC not processed results in 402 response
- Alpha Vantage rate limits exceeded returns throttle error
- Invalid ticker symbol returns no data or error message
