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 agent402-holiday-regions-list-5de1368a
```

Example prompt: Before I call the business-days-static endpoint, can you check which holiday region codes are available — specifically whether Japan and Singapore are supported?

## When to prefer this

Use this endpoint as a discovery step before calling the business-days-static endpoint to validate that your target country code is supported. Prefer this over hardcoding region codes, since the supported list may be updated over time. Ideal when dynamically building region selectors or validating user-supplied country inputs at runtime.

## Known failure modes

- Network error or service unavailability returning a 5xx response
- Payment failure via x402 protocol (insufficient USDC balance or incorrect payment header) returning 402
- Unexpected empty regions array if backend data is misconfigured

## How this service works

Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.

## Output

A JSON object containing a 'regions' array of ISO country code strings (e.g. ['AU','DE','FR','IE','JP','SG','US']) representing all country/region codes for which static public holiday calendars are available on the platform.
