## 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 sitecheck-trade-energy-us-de-minimis-section-321-checker-5a7ebf8b
```

Example prompt: Check whether the US de minimis exemption under Section 321 is currently active or suspended, and tell me if a $450 shipment can enter duty-free today.

## When to prefer this

Use this endpoint when you need a real-time, authoritative check on US Section 321 de minimis status grounded in the latest Federal Register and CBP documents — especially when the regulatory environment is volatile (active suspension orders). Prefer over manual research or static databases when you need both the current threshold values and the specific legal document citations backing the status determination.

## Known failure modes

- Federal Register API unreachable — may return stale or cached suspension status
- Invalid or non-numeric valueUsd query parameter — may cause parsing error or ignored parameter
- Suspension status may lag real-world effective date if Federal Register documents are published after effective date
- Truncated presidential/CBP document lists if many documents match the query

## How this service works

US de minimis (Section 321) check: the $800 per person per day limit (plus $100 gift and $200 traveller limits), whether duty-free de minimis is currently suspended according to the newest Federal Register documents, and whether a shipment value can enter duty-free today. Lists the latest CBP rules and presidential documents on de minimis with dates, numbers and links.

## Output

Returns a JSON object containing: whether de minimis is currently suspended (boolean), the basis for the suspension status (title, date, document number, Federal Register URL), the current monetary limits ($800 per-person-per-day, $100 gift, $200 traveller), whether a supplied shipment value is under the limit and qualifies for duty-free entry, the governing statute (19 U.S.C. 1321(a)(2)), a list of the latest CBP rule/notice documents with titles, dates, and URLs, a list of the latest presidential documents on de minimis, and a timestamp of when the check was performed.
