## 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 orcpin-single-trade-t-1-settlement-date-64875580
```

Example prompt: What's the T+1 settlement date for a trade executed on 2025-06-10, and has it settled as of today 2025-06-12?

## When to prefer this

Prefer this endpoint when you need to compute the settlement date for a single trade quickly without constructing a request body — ideal for lightweight, real-time queries in agent pipelines. Choose this over the batch sibling when you have only one trade to resolve, want low-latency lookup, or are building a simple compliance check. It is authoritative on NYSE holiday calendar versioning and explicitly cites SEC Rule 15c6-1, making it suitable for regulated contexts.

## Known failure modes

- Missing required query params (trade_date or as_of) returns a 400 error
- Invalid date format (not YYYY-MM-DD) causes a parse error
- Trade date falling on a weekend or NYSE holiday may return an adjusted settlement date or an error
- Payment failure via x402 returns a 402 status, blocking the response
- Stale or mismatched calendar version may produce unexpected settlement dates around newly declared NYSE holidays

## How this service works

Single-trade T+1 settlement date, as a one-line GET: given a trade date and an as-of date, returns the settlement date and whether it has settled, on the versioned NYSE holiday calendar with SEC Rule 15c6-1 cited. The low-integration sibling of the batch settlement-dates route — no request body. A dates fact, never a violation determination. Nothing is stored.

## Output

A JSON object containing the computed settlement date (YYYY-MM-DD), a boolean indicating whether the trade has settled as of the as-of date, the number of trading days remaining until settlement, the NYSE calendar version used, the SEC Rule 15c6-1 citation, the schema version, and an optional echoed ticker symbol plus a disclaimer.
