## 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-europe-exchange-holiday-calendars-382cf153
```

Example prompt: Can you pull the audited holiday calendar for all 29 European stock exchanges from StockQL so I can see which venues have full-day closures and what the trading weeks look like, along with the provenance manifest?

## When to prefer this

Choose this endpoint when you need authoritative, audited exchange holiday calendars specifically for European venues with full provenance tracing. It is preferable over generic market data APIs when compliance, auditability, and operator-sourced verification matter — especially for trading systems, settlement scheduling, or regulatory reporting that requires documented data lineage across all 29 European exchange venues.

## Known failure modes

- HTTP 402 Payment Required if USDC payment is not attached or insufficient
- HTTP 404 if the calendars endpoint is unavailable or region path is wrong
- Stale data if audit horizon has not been refreshed for a venue
- Incomplete provenance manifest if operator source for a venue is temporarily unavailable
- Network timeout on large calendar dataset responses

## How this service works

Audited EUROPE exchange holiday calendars (29 venues): trading weeks, full-day closures, audit horizons, operator sources, provenance manifest.

## Output

A structured dataset covering 29 European exchange venues, including: trading week definitions (which days constitute a trading week per venue), full-day closure dates (exchange-specific holidays), audit horizons (the date range covered and audited), operator sources (the authoritative source for each venue's calendar), and a provenance manifest documenting data lineage and verification.
