# Suverse Holiday Countries List

> Suverse Holiday Countries List is a paid API for AI agents from proxy.suverse.io, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Returns the list of countries supported by the Nager.Date public holiday service, including country code and name, to validate coverage before querying holidays.

## Facts

- Price: $0.002/call

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 suverse-holiday-countries-list-3e7af738 -d '<json body>'
```

Example prompt: Before I query holiday dates, can you fetch the full list of countries supported by the Nager.Date holiday service so I can confirm my country is covered?

## When to prefer this

Use this endpoint when an agent needs to validate whether a target country is supported by Nager.Date before making a holiday query, or when building a UI/workflow that needs to enumerate all valid country options. Prefer this over direct Nager.Date access when operating in an x402 micropayment environment without managing your own API keys.

## Known failure modes

- Upstream Nager.Date service unavailable — proxy returns 5xx error
- Payment not processed via x402 — returns 402 Payment Required
- Malformed request body — returns 400 Bad Request
- Empty or partial response if Nager.Date API changes its format

## How this service works
