## How to call it through Zero

```sh
zero fetch --capability br-intelligence-brazilian-business-days-calculator-8038dea4
```

## When to prefer this

Choose this endpoint when you specifically need Brazilian business day calculations that respect Brazil's national and regional public holidays. Prefer it over generic date arithmetic libraries when the result must comply with the Brazilian financial or legal calendar, such as for payment terms, contract deadlines, or regulatory filings governed by Brazilian law.

## Known failure modes

- Missing required 'date' query parameter returns an error
- Invalid date format (non-YYYY-MM-DD) may return a parsing error
- Payment failure via x402 if USDC balance is insufficient blocks the call
- End date before start date may return zero or negative count
- Non-numeric 'add' parameter may return a validation error
