# krx — a service's fields Show the columns one KRX service returns, by the readable `group name` pair the Python client uses. `krx fields <group> <method>` prints the field (column) names in the order KRX returns them -- `krx fields index kospi` gives `BAS_DD`, `IDX_CLSS`, `IDX_NM`, `CLSPRC_IDX`, ... It reads a schema **bundled in the krx-openapi package**, so it runs **offline and needs no API key**. ## Prerequisite This plugin calls the `krx` CLI, so the package must be installed: ``` pipx install krx-openapi # or: pip install krx-openapi ``` That puts the `krx` command on PATH. `krx fields` needs **no** `KRX_API_KEY` (it is offline) -- only the **fetch** skill does. ## Running ``` krx fields <GROUP> <NAME> # the field (column) names that service returns ``` - `GROUP NAME` is the readable service pair -- `index kospi`, `stock daily`, `bond treasury`, ... If you don't have it, use the **list** skill (`krx list`) first. - `--json` emits JSON instead of the text view. ## Procedure 1. **Have the `group name`.** If the user gave only a concept, use the **list** skill (`krx list`) to find the pair first. 2. **Run.** ```bash krx fields index kospi ``` 3. **Relay the result.** Show the CLI's stdout -- the column names the fetched rows will carry. Offer to hand the same `group name` to the **fetch** skill for the data. 4. **Error handling.** An unknown method exits 2 with `krx: unknown service ...` -- relay it and suggest `krx list <group>` to
