## 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 prysm-alpha-vantage-provider-0963595c -d '<json body>'
```

Example prompt: Pull me the latest stock quote for AAPL using the Alpha Vantage quote operation — I need the current price, open, high, low, and volume.

## When to prefer this

Choose this endpoint when you need Alpha Vantage financial market data (quotes, time series, technical indicators) and want to pay per-call via x402 USDC micropayment on Base mainnet without managing an Alpha Vantage API key directly. Prefer it for agent workflows that require on-demand, pay-as-you-go financial data access within a crypto-native payment stack.

## Known failure modes

- Unsupported operation name returns an error indicating the operation is not allowlisted
- Missing or malformed `input` parameters cause downstream Alpha Vantage errors surfaced in the response
- Payment failure over x402 results in a 402 response before the operation is attempted
- Rate limits or API quota exhaustion on the Alpha Vantage backend may return empty or error data
- Invalid ticker symbol returns empty or error data from Alpha Vantage

## How this service works
