## 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 tradepulse-hs-code-classifier-d511734e
```

Example prompt: What's the correct HS code for 'wireless noise-cancelling over-ear headphones with Bluetooth 5.0 and a built-in microphone' so I can file the customs declaration for my shipment?

## When to prefer this

Use this endpoint when you need an authoritative HS code for a specific product description for customs filing, import/export declarations, or trade compliance purposes. Especially useful for agents automating customs workflows or duty calculations where an accurate tariff classification is the first required step. Pair with the TradePulse tariff rate lookup and landed cost calculator siblings for end-to-end trade cost computation.

## Known failure modes

- Ambiguous product description resulting in multiple possible HS codes
- Product description too vague to classify accurately
- Unrecognized or novel product categories with no clear HS mapping
- Payment failure or insufficient USDC balance ($0.15 per call)
- API timeout or service unavailability
