## 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-weekly-time-series-via-locus-x402-a247e854 -d '<json body>'
```

Example prompt: Can you pull the weekly OHLCV time series data for AAPL — I want to see how the stock has moved week by week over its full available history?

## When to prefer this

Use this endpoint when you need weekly-granularity OHLCV equity data with pay-per-call micropayment billing via x402, avoiding API key management. Prefer over daily endpoints when analyzing long-term trends or when bandwidth/cost per data point is a concern. Best for agents that need structured historical stock data on demand without a subscription.

## Known failure modes

- Invalid or unknown ticker symbol returns empty or error data object
- Missing required 'symbol' field causes request failure
- x402 payment authorization failure blocks the call
- Rate limiting from upstream Alpha Vantage causes delayed or rejected response
- Network timeout from the Locus proxy layer
