## 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 stablefinance-balance-sheets-api-18801a85
```

Example prompt: Pull Apple's annual balance sheet from Financial Datasets AI — I want to see total assets, total liabilities, shareholders equity, and cash for the most recent fiscal year, limited to 1 result.

## When to prefer this

Use this endpoint when you need structured balance sheet fundamentals for a publicly traded US company — especially assets, liabilities, equity, and debt — and want pay-per-request access without a subscription. Prefer this over general financial APIs when you need clean, structured JSON output with date-range filtering and period-type control.

## Known failure modes

- Missing required 'period' parameter returns a 400 validation error
- Invalid ticker symbol returns empty balance_sheets array
- CIK not found returns empty results
- report_period date format must match YYYY-MM-DD exactly or validation fails
- Limit exceeds 50 returns a validation error
- Payment of 0.02 USDC not received triggers HTTP 402 before data is returned

## How this service works

Normalized balance sheets.

## Output

Returns an array of balance sheet records, each containing ticker, period type (annual/quarterly/ttm), fiscal period label, report date, total assets, total liabilities, shareholders equity, total debt, current assets, and cash and equivalents — all in USD.
