## 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 lilambd-koyomi-public-holidays-lookup-9d305098
```

Example prompt: What are all the public holidays in Germany for 2025? Give me the full list including any regional ones for Bavaria.

## When to prefer this

Choose this endpoint when you need structured, machine-readable public holiday data for a specific country and year, especially when you need subdivision-level granularity or multilingual holiday names. It is priced per-call at $0.05 USDC via x402 micropayment, making it suitable for on-demand lookups in agent workflows rather than bulk calendar generation. Prefer this over scraping government sites or using static datasets when freshness and attribution matter.

## Known failure modes

- Missing required 'country' parameter returns a validation error
- Invalid or unsupported country code returns empty data array or error
- Unsupported year range may return empty results
- Invalid subdivision code silently returns national holidays or empty set
- Network or upstream data source unavailability returns 5xx error
- Payment failure (x402) prevents access to the endpoint

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing an array of holiday entries (dates and names) for the requested country and year, a count of results, and an attribution string crediting the data source license. Individual holiday objects likely include date, name, and possibly type or subdivision fields.
