## 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-balance-sheet-via-locus-x402-4387db06 -d '<json body>'
```

Example prompt: Pull up the balance sheet for MSFT — I want to see their total assets, liabilities, and shareholders' equity across recent quarters.

## When to prefer this

Choose this endpoint when you need structured, machine-readable balance sheet data for a publicly traded company and want to pay per-call without a subscription. It is ideal for agents doing on-demand fundamental analysis, financial screening, or portfolio research where balance sheet data is needed infrequently or for a variable set of tickers. Prefer it over subscription APIs when cost predictability at low query volumes matters, or when integrating into a crypto-native or x402-enabled payment workflow.

## Known failure modes

- Invalid or unrecognized ticker symbol returns empty or error data object
- Missing 'symbol' field in request body causes a validation error
- Payment failure or insufficient USDC balance blocks the request
- Endpoint may return incomplete data for tickers with limited financial reporting history
- Rate limiting or upstream Alpha Vantage API unavailability may result in failed responses
