## 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 pocket-network-korean-apartment-trade-data-api-8f14bf17 -d '<json body>'
```

Example prompt: What did apartments actually sell for in Gangnam (강남구) in October 2024? Show me the monthly median and quartile prices, and pull the last 6 months of trend data.

## When to prefer this

Choose this endpoint when you need authoritative, government-registered apartment sale transaction data for South Korea, including real prices paid, area, floor, and cancellation status. It is ideal when you need MOLIT-sourced data rather than listing estimates, and when you need historical trends or complex-level breakdowns. It supports both structured queries and natural language questions in Korean or English.

## Known failure modes

- Invalid or unrecognized LAWD_CD or district name returns an error or empty result
- Apartment complex name not in Korean causes lookup failure
- Month parameter outside available data range returns no records
- Payment in USDC not processed correctly via x402 results in 402 error
- Natural language question ambiguous or not mappable to a supported query type

## How this service works

What apartments in a Korean district actually sold for, from MOLIT's real-transaction register: each reported sale with price in KRW, area, floor and cancellation flag, monthly medians and quartiles, trends, and one complex across months. Use GET /v1/trades, /v1/trend or /v1/complex; POST /v1/query answers district trend questions in Korean or English. Pay per request in USDC; no API key.

## Output

Returns actual MOLIT-registered apartment sale transactions for the requested district or complex, including individual sale records (price in KRW, area in m², floor, cancellation flag) and aggregate statistics (monthly median, quartiles, and trend data over multiple months).
