## 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 japan-trade-statistics-api-un-comtrade-a020bae4
```

Example prompt: Pull Japan's export data to China (partner code 156) for 2023 — I'm doing a supply chain analysis and need the UN Comtrade bilateral trade values in USD.

## When to prefer this

Use this endpoint when you need official UN Comtrade bilateral trade statistics specifically for Japan — imports or exports by partner country and commodity — for supply chain research, market entry analysis, tariff impact studies, or trade flow monitoring. Prefer this over generic trade databases when Japan-specific HS-level annual data in USD is required.

## Known failure modes

- Invalid or unsupported year returns empty or error response
- Unknown UN partner country code returns no data
- Missing required query parameters may return all data or an error
- Data unavailable for very recent years not yet published by UN Comtrade
- Payment failure (HTTP 402) if x402 payment is not completed

## How this service works

## Output

Returns annual USD trade values for Japan's imports or exports with a specified partner country (or world aggregate), broken down by HS commodity code, sourced from UN Comtrade official data.
