## 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-trade-statistics-kosdaq-opendart-bundle-7c27bbc9
```

Example prompt: Download the latest KMDE data bundle for me — I need the Korean HS854232 trade statistics, the 7-day KOSDAQ OpenDART disclosures, and the Base ERC-20 contract basics all in one ZIP.

## When to prefer this

Choose this endpoint when you need a bundled, pre-packaged snapshot of Korean HS854232 trade statistics combined with KOSDAQ OpenDART recent disclosures and Base ERC-20 contract data in a single low-cost ($0.1 USDC) call. Prefer this over building separate API integrations with OpenDART, Korean customs data providers, and Base blockchain indexers individually. Best for agents that need a cross-domain Korean market + blockchain data snapshot without real-time streaming requirements.

## Known failure modes

- Payment not received or x402 payment protocol failure — endpoint returns 402 Payment Required
- Network timeout from Render hosted service — service may be cold-starting
- Invalid or malformed Idempotency-Key header — may return 400 Bad Request
- ZIP archive may be incomplete or empty if upstream data sources (OpenDART, Korean customs) are unavailable
- Stale data if the snapshot has not been refreshed recently
