## 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 alpha-vantage-via-apiosk-gateway-64209d08
```

Example prompt: Pull the latest daily OHLCV data for AAPL from Alpha Vantage using the TIME_SERIES_DAILY function — I want to see the past 30 days of closes.

## When to prefer this

Choose this endpoint when you need Alpha Vantage's broad financial data coverage — stocks, forex, crypto, technicals, and fundamentals — and want to pay per call in USDC without managing an Alpha Vantage API key directly. Prefer this over direct Alpha Vantage integration when operating in an agent environment using the x402 payment protocol on Base.

## Known failure modes

- Missing or invalid 'function' parameter returns an error
- Unknown or unsupported function name returns Alpha Vantage error message
- Invalid or delisted ticker symbol returns empty or error data
- Rate limit exceeded on underlying Alpha Vantage plan returns throttle error
- Payment failure on x402 protocol causes 402 response before data is returned

## How this service works

All Alpha Vantage data via a function param, e.g. GLOBAL_QUOTE, TIME_SERIES_DAILY, CURRENCY_EXCHANGE_RATE, DIGITAL_CURRENCY_DAILY.

## Output

Returns JSON data from Alpha Vantage corresponding to the requested function — e.g. time series OHLCV arrays, real-time quotes, technical indicator series, forex rates, or fundamental metrics, all in Alpha Vantage's standard response envelope.
