## 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 strale-employment-cost-estimate-api-a6131240
```

Example prompt: What's the total employer cost to hire someone with a gross salary of 90000 USD in Germany — I need to understand all the mandatory contributions and taxes on top of the base salary.

## When to prefer this

Choose this endpoint when you need a fast, country-specific estimate of the true employer cost of hiring — including all mandatory payroll taxes and contributions — without needing a full HR or payroll system integration. It is especially useful for budget planning, market expansion analysis, or comparing hiring costs across the 27+ supported countries. Prefer it over generic payroll tools when you need structured JSON output with audit trails suitable for agent workflows and x402 micropayment-based access.

## Known failure modes

- Missing required gross_salary or country_code query parameters returns a 400 error
- Unsupported or invalid country_code returns an error or empty result
- Currency mismatch or unsupported currency code may cause calculation errors
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Rate limiting or service unavailability returns a 5xx error
- Data may be outdated if local tax regulations have recently changed
