## 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 api-strale-io-ab0cb46b
```

Example prompt: What's the HS code for 'stainless steel kitchen knives'? I need the primary code, chapter, and any alternative classifications with confidence scores for a customs declaration.

## When to prefer this

Use this endpoint when you need to classify a product for international trade, customs declarations, import/export compliance, or tariff determination and want confidence-scored alternatives rather than a single guess. Prefer this over manual lookup when automating supply chain workflows or e-commerce cross-border shipping.

## Known failure modes

- Product description too vague or ambiguous — returns low-confidence results or multiple alternatives
- Unrecognized product category — returns no match or generic fallback
- Missing required 'product' query parameter — returns validation error
- Service unavailable or payment failure — returns 402 or 5xx error
- Very niche or proprietary product names not in HS taxonomy — may misclassify

## How this service works

Classify a product into Harmonized System (HS) commodity codes. Returns primary HS code, chapter, section, and alternative classifications with confidence levels.

## Output

Returns the primary HS code with its chapter and section, plus a list of alternative HS classifications each with associated confidence levels, enabling trade compliance and customs filing decisions.
