## 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-korea-hs854232-trade-statistics-hong-kong-export-changes-9c983dd6
```

Example prompt: Can you pull the latest South Korea HS 854232 semiconductor export data for Hong Kong from the KMDE snapshot versioned 20261007T045335Z? I need the month-over-month and year-over-year change figures.

## When to prefer this

Use this endpoint when you need a fixed, versioned snapshot of South Korean HS 854232 (integrated circuits/processors) export trade statistics specifically for Hong Kong, with quantified MoM and YoY change metrics. Prefer this over live government trade portals when reproducibility and version consistency matter, or when you need machine-readable JSON with structured change metrics rather than raw data tables. The x402 micropayment model ($0.005 USDC) makes it suitable for agents that need occasional, on-demand trade data lookups without a subscription.

## Known failure modes

- 402 Payment Required if x402 micropayment not completed
- Version not found if snapshot timestamp is invalid or expired
- Country code mismatch if path parameter deviates from 'HK'
- Service unavailable if Render.com hosting is cold-starting or under load
- Partial data returned if only free-tier fields accessible without payment

## Output

A JSON object containing: scope metadata (HS code 854232, reporting country KR, destination HK, USD FOB unit), snapshot version timestamp, product ID, latest period (YYYYMM format), and — behind the x402 paywall — latest export value in USD, month-over-month change, year-over-year change, revision history, and source observation details.
