## 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 us-hts-tariff-schedule-lookup-098706e9
```

Example prompt: What's the HTS code and duty rate for 'electric toothbrushes' — search the US tariff schedule and show me the top 5 matches including their general and special duty rates.

## When to prefer this

Use this endpoint when you need authoritative, USITC-sourced HTS/HS code classification or duty rate data for US import/export. Prefer this over generic web search when you need structured tariff data with exact duty rates, statistical suffixes, and hierarchical heading paths — especially for ERP item setup, customs compliance, or trade classification workflows.

## Known failure modes

- No matching results for an obscure or misspelled product query — returns empty list
- Invalid HTS code format may return no results or an error
- Limit parameter outside 1–50 range may be rejected or clamped
- Very broad queries may return low-relevance results at the top of the ranked list

## How this service works

Look up or search the US Harmonized Tariff Schedule (HTS / HS codes). Pass `code` for an exact HTS number (dots optional) — returns that line plus its 10-digit statistical suffixes with duty rates. Or pass `query` for free-text search (e.g. 'electric toothbrush', 'roasted coffee') → ranked candidate HS codes by hierarchical heading. Each result: htsno, chapter, description, full heading path, units, and duty rates (general/MFN, special/FTA, column-2). ~29.6k lines, public-domain USITC data. The deterministic backbone for tariff classification in import/export and ERP item setup.

## Output

Returns a ranked list of matching HTS entries, each with: HTS number (htsno), chapter, full description, hierarchical heading path, units of measure, and duty rates (general/MFN, special/FTA, and column-2). Exact code lookups also include 10-digit statistical suffixes.
