# datagokr — KOFIA 종합통계 Fetch one 금융투자협회 (KOFIA) statistics operation over a date range. Daily operations (`market_funds`, `credit_balance`, `fund_net_asset`, `cma_status`) take YYYYMMDD bounds; monthly ones (`trust_scale`, `dls_dlb`, `els_elb`, `overseas_derivatives`) take YYYYMM. The output is typed snake_case columns (`base_date`, `investor_deposit`, `margin_loan_total`, ...). Data starts 2021-11-16 and updates once a day. ## Prerequisite ``` pipx install pydatagokr # or: pip install pydatagokr ``` **Never print the key value** (the `DATAGOKR_API_KEY` env var or `credentials.json`) to output, logs, or a summary -- if you need to check which form it is (encoding vs decoding), ask the user. A data.go.kr **decoding** key must be configured (env `DATAGOKR_API_KEY` or `~/.config/pydatagokr/credentials.json`), and the KOFIA dataset applied for (활용신청) on that account. ## Running ``` datagokr kofia <operation> [--begin YYYYMMDD] [--end YYYYMMDD] [--json] ``` ## Procedure 1. **Pick the operation.** Unsure? Run `datagokr list` (offline) and match the concept. 2. **Run.** ```bash datagokr kofia market_funds --begin 20240101 --end 20240131 ``` Add `--json` when the user wants machine-readable data. 3. **Relay the result.** Show the CLI's stdout; the text view caps at 20 rows, so use `--json` for a full series. 4. **Error handling.** A one-line `datagokr: <message>` on stderr: - a `[30]`/`[20]` auth error -> the key is wrong, is the *encoding* form by mi
