## 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

```

Example prompt: Can you look up the US import duty evidence for HTS code 8471300000 imported from China, with a customs value of $12000?

## When to prefer this

Use this endpoint when you need official US HTS duty evidence for a specific 10-digit HTS code or want to search by product description. Particularly valuable when importing from China and needing Section 301 tariff applicability signals. Best for pre-import cost estimation and tariff classification research rather than definitive legal tariff advice.

## Known failure modes

- Missing or invalid HTS code returns no duty estimate — 10-digit exact code required for numeric estimate
- Product description search may return unverified candidate codes
- Section 301 evidence only available when origin country is CN/China
- Customs value must be between 0 and 1,000,000,000 USD
- Query string must be 2–120 characters
- Payment failure or insufficient USDC balance blocks the request

## How this service works

Official current US HTS evidence; 10-digit exact code required for PARTIAL numeric duty estimate. Candidate codes are unverified; no verified legal tariff changes or all-in duty. $0.004 USDC.

## Output

Returns official US HTS duty evidence including tariff classification details, applicable duty rates, and (when a 10-digit code and customs value are provided) a partial numeric duty estimate. For Chinese-origin goods, includes USTR Section 301 applicability evidence. Note: candidate codes are unverified and no verified legal tariff changes or all-in duty totals are guaranteed.
