## 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 business-days-calculator-46d66c26
```

Example prompt: How many business days are there between March 3 and April 18, 2025? I need to figure out the exact working-day count for a contract deadline.

## When to prefer this

Choose this endpoint when you need a quick, deterministic, pay-per-call business-days computation without signing up for a scheduling SaaS or setting up API keys. It is ideal for agents that occasionally need date arithmetic in workflows — invoicing, contract management, project planning — and want to pay micro-amounts per call via USDC rather than maintain a subscription.

## Known failure modes

- Invalid or unparseable date format returns an error
- Missing required date parameters returns a validation error
- Unsupported locale or country code may result in incorrect holiday exclusions
- Payment failure via x402 returns HTTP 402 before the computation runs
- Ambiguous date ranges (end before start) may return zero or negative counts

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output

Returns a JSON object indicating success, the computed number of business days or resulting date, with weekends and public holidays excluded from the count.
