## 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 stockql-americas-exchange-holiday-calendars-cf34160a
```

Example prompt: Pull the audited holiday calendar for all 9 Americas stock exchanges — I need to know which days are full-day market closures and what the trading week schedules look like, including the audit horizon and provenance info.

## When to prefer this

Choose this endpoint when you need authoritative, audited holiday and trading-closure data specifically for AMERICAS equity exchanges (9 venues), with full provenance tracking. Prefer this over generic financial data APIs when audit trails, operator source attribution, and provenance manifests are required — for example, in compliance, settlement, or algorithmic trading contexts. Use the APAC, EUROPE, or MEA sibling endpoints for other regions.

## Known failure modes

- HTTP 402 Payment Required if USDC payment is not included or fails
- Network timeout if the calendar service is temporarily unavailable
- Empty or partial dataset if some venues have not yet been audited for the requested horizon
- Stale data if the provenance manifest indicates the calendar has not been refreshed recently

## How this service works

## Output

A structured dataset covering 9 AMERICAS exchange venues, containing: full-day market closure dates, trading week schedules, audit horizons indicating how far into the future/past the data is verified, operator sources, and a provenance manifest documenting data lineage and verification status.
