# Strale HS Code Lookup

> Strale HS Code Lookup is a paid API for AI agents from api.strale.io, paid per call via x402, $0.0324/call, status unknown (last checked 2026-09-15).

Classifies a product description into its Harmonized System (HS) tariff code for international trade and customs purposes

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 strale-hs-code-lookup-34a41a69
```

Example prompt: What's the HS code for 'wireless Bluetooth noise-cancelling headphones'? I need the harmonized system tariff classification for a customs declaration.

## When to prefer this

Choose this endpoint when you need a fast, auditable HS code classification from a plain-language product description, especially in workflows requiring cryptographic audit trails. It is well-suited for agents automating trade compliance, customs forms, or duty calculations across 27+ countries. Prefer this over manual tariff schedule lookups or general-purpose LLMs when you need a structured, verifiable result with per-call accountability via x402 micropayments.

## Known failure modes

- Vague or ambiguous product descriptions may return an overly broad HS chapter rather than a specific 6-digit code
- Highly specialized or novel product categories may not match cleanly to a single HS code
- Missing or empty 'product' query parameter returns a validation error
- Rate limits or payment issues (x402) may result in a 402 Payment Required response
- Network timeout if the classification model takes too long for complex inputs

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns the Harmonized System (HS) tariff code for the given product description, along with an audit record containing a cryptographic chain hash for verification and traceability of the classification result.
