## 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 nyse-market-holidays-and-early-closes-609ae333
```

Example prompt: What are all the NYSE market holidays and early closes for 2025? I need the full list with dates and weekdays.

## When to prefer this

Choose this endpoint when you need a complete, authoritative list of all NYSE market holidays and early closes for an entire year in a single call. It is ideal for building trading calendars, scheduling financial workflows, or validating settlement dates. Prefer this over a 'is market open' single-date check when you need bulk planning data for a full year, and over country-specific public holiday endpoints when you specifically need NYSE/US equity market closure rules (which differ from US federal holidays).

## Known failure modes

- Year outside 1990–2100 range returns a validation error
- Missing required 'year' query parameter returns a 400-level error
- Data may be marked as degraded if source rules cannot be fully verified for a distant future year
- Edge years near boundaries of published NYSE rules may have incomplete or estimated data

## How this service works

NYSE market holidays and 1 PM early closes for a year, with the weekday of each, from the exchange's published rules.

## Output

Returns a structured object containing: the queried year, a list of full market closure dates (each with date string, holiday name, and weekday), a list of early close dates (each with date, reason, close time in ET, and weekday), the data source attribution, an asOf timestamp, a summary, a verdict, a disclaimer, and flags for degraded data or unchecked items.
