## 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 steward-settlement-day-checker-44b23dff
```

Example prompt: Is December 26, 2025 a Fedwire settlement day, or do I need to plan for the next available Fed settlement date?

## When to prefer this

Use this endpoint when an agent needs to confirm whether a specific date is a valid settlement day for Fedwire or TARGET2 before scheduling or routing a payment. Prefer it over manual calendar lookups or holiday APIs that don't understand payment-system-specific settlement rules (e.g. Fed-observed holidays like Columbus Day or Juneteenth). Ideal for treasury automation, payment orchestration agents, or any workflow where value-date accuracy matters.

## Known failure modes

- Invalid date format (not YYYY-MM-DD) returns an error
- Unrecognized system value (not 'fed' or 'target2') may default or error
- Dates far in the future may not have holiday calendars populated
- Payment required (402) if USDC payment header is missing or insufficient

## How this service works

Use when an agent needs to know whether a date settles — is it a Fedwire/Fed or TARGET2 (ECB) settlement day, is it a holiday or weekend, and what is the next settlement day. Computed locally from the holiday calendars, no upstream. Pass date (default today) and system (fed or target2). Use permitted: build it into your products and services, paid or free. Raw redistribution of the feed itself is prohibited.

## Output

Returns whether the queried date settles on the specified payment system (Fedwire or TARGET2), whether it is a holiday or weekend, and the next valid settlement date — computed locally from embedded holiday calendars with no upstream dependency.
