## 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 kmde-data-api-korea-hs854232-trade-statistics-japan-export-changes-ccfa7801
```

Example prompt: Pull the versioned KMDE snapshot for South Korea's HS 854232 semiconductor export changes to Japan — I need the MoM and YoY figures for the latest period.

## When to prefer this

Use this endpoint when you need a fixed, versioned snapshot of South Korea's HS 854232 (semiconductor/integrated circuit) export trade change statistics specifically to Japan, with MoM and YoY metrics. It is ideal for reproducible research or time-stamped comparisons since the version is pinned. Prefer this over generic trade databases when you need structured, machine-readable JSON with revision history and a low per-call cost via x402 micropayment.

## Known failure modes

- Version not found: requesting an invalid or future snapshot version returns an error
- Country code mismatch: only JP is valid for this endpoint path
- Payment not processed: without x402 payment, paid fields (exports_usd, MoM, YoY, revisions) are withheld or null
- Service unavailable: hosted on Render free tier, may experience cold start latency or downtime
- Rate limiting: repeated calls without valid payment headers may be rejected

한국 HS854232 무역 통계, 코스닥 OpenDART 7일 공시 목록과 Base ERC-20 계약 기초 사실의 무료 목록·샘플 및 x402 고정 버전 JSON API.

## Output

A JSON object containing: the trade scope metadata (HS code 854232, Korea-to-Japan export direction, USD FOB unit), the snapshot version timestamp, the product ID, a list of paid fields (exports_usd, MoM, YoY, revisions, source_observation), and the latest reporting period (e.g. 202608). Full numeric values for exports, MoM and YoY changes, and revision data are gated behind payment.
