## How to call it through Zero

```

## When to prefer this

Choose this endpoint when you need a fast, deterministic first-pass triage of HS-2022 headings for a goods description — especially useful for pre-classification research, duty estimation workflows, and compliance checks where you want ranked candidates with official heading text and GRI rationale. It is not a binding customs ruling, so pair it with a licensed customs broker for final classification decisions. Prefer this over generic web searches when you need structured, ranked output tied directly to HS-2022 heading numbers.

## Known failure modes

- Missing or empty 'q' query parameter returns a 400 error
- Extremely vague or ambiguous descriptions may return low-confidence or no candidates
- HS code database may not reflect the very latest 2022 amendments for niche goods
- Payment failure (x402) results in 402 response and no classification data
- Rate limiting may occur under heavy query volume

## How this service works

Deterministic HS-code triage: ranked candidate headings with official heading text, GRI note and broker disclaimer. Not a customs ruling.

## Output

A ranked list of candidate HS-2022 four-digit headings, each with its official WCO heading text, the relevant General Rules for Interpretation (GRI) note explaining why it applies, and a broker disclaimer stating this is not a binding customs ruling.
