# data-go-kr — 관세청 수출입 무역통계 Fetch one HS code's monthly 수출입실적 over a YYYYMM range. Clean columns: `period` (YYYY-MM), `hs_code`, `item_name`, `export_usd`, `export_weight_kg`, `import_usd`, `import_weight_kg`, `trade_balance_usd` (all amounts/weights are integers). `--json` returns the full typed rows. ## Prerequisite ``` pipx install data-go-kr # or: pip install data-go-kr ``` A data.go.kr **decoding** key must be configured (env `DATA_GO_KR_API_KEY` or `~/.config/data-go-kr/credentials.json`), and the 수출입 무역통계 dataset (service 1220000) applied for (활용신청) on that account. ## Running ``` data-go-kr customs item_trade <HS> --begin YYYYMM --end YYYYMM [--json] ``` ## Procedure 1. **Get the HS code.** Take it from the user (e.g. semiconductors 8542, cars 8703); 2-, 4-, 6-, or 10-digit prefixes narrow or widen the item. 2. **Run.** ```bash data-go-kr customs item_trade 8542 --begin 202401 --end 202406 ``` Add `--json` when the user wants machine-readable data. 3. **Relay the result.** Show the CLI's stdout (the clean columns above). 4. **Error handling.** A one-line `data-go-kr: <message>` on stderr: - a `[30]`/`[20]` auth error -> the key is wrong, is the *encoding* form by mistake, or service 1220000 is not applied for yet. - a `[22]`/`[23]` rate limit -> the daily traffic limit; wait and retry. ## What this skill does not do - It does not re-implement fetching or parsing (the package does); it always calls the CLI. - KOFIA market statis
