## 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 us-trade-flow-statistics-by-hs-code-aaa23e94
```

Example prompt: Can you pull US import statistics for HS code 8471.30 for 2023, filtered to imports from China?

## When to prefer this

Use this endpoint when you need structured US trade flow data (imports or exports) for a specific HS or HTS tariff code, optionally narrowed by year and partner country. It is suitable for trade research, compliance checks, sourcing analysis, and market intelligence tasks where Census-level commodity trade statistics are needed.

## Known failure modes

- Invalid or malformed HS code returns an error or empty result
- Unsupported year range may return null or no data
- Unknown partner country code may be ignored or cause an error
- Missing required 'hs6' parameter returns a validation error
- Payment failure via x402 protocol blocks the request entirely

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object with a 'success' boolean and a 'result' object containing trade flow statistics such as import or export volumes, values, and partner breakdowns for the specified HS/HTS code, year, and direction.
