Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Is July 4th 2025 a public holiday in the US? If so, what's the holiday name and type, and what's the next holiday coming up that year?

## When to prefer this

Use this endpoint when you need a quick, low-latency point-in-time check on whether a specific date is a public holiday in a particular country, and want the holiday name and type alongside the next upcoming holiday. Prefer this over calendar scraping or general-purpose web search when you need structured, programmatic holiday data for scheduling, compliance, or workflow automation.

## Known failure modes

- Invalid or unsupported country code returns an error or empty result
- Date format not matching YYYY-MM-DD pattern causes a validation error
- Date outside supported range may return no data
- Network or upstream data source unavailability causes a 5xx error
- Payment failure (x402) prevents the request from being processed
