# finyahoo — price history Take a ticker and print its OHLCV bars (with the split and dividend events over the same span). The fetching and parsing live in the finyahoo package (on PyPI); this skill is a thin wrapper that calls its CLI and relays the result. A delisted ticker, a rate block, and the like come back from the CLI as a one-line error -- relay that message as-is rather than throwing a stack trace at the user. ## Prerequisite This plugin calls the `finyahoo` CLI, so the package must be installed first: ``` pipx install finyahoo # or: pip install finyahoo ``` That puts the `finyahoo` command on PATH. No API key or login is needed -- Yahoo's endpoints are public and the client handles the session token itself. ## Running ``` finyahoo history "<SYMBOL>" [options] ``` Options (`finyahoo history --help` is the source of truth): - `--start YYYY-MM-DD` — inclusive start date (default: Yahoo's earliest bar). - `--end YYYY-MM-DD` — inclusive end date (default: the latest bar). - `--timeframe day|week|month` — bar size (default: day). - `--json` — full series as JSON instead of the text summary. The text output is a one-line summary (symbol, bar count, split/dividend counts) plus the most recent few bars. Use `--json` when the user wants the whole series or machine- readable data. ## Procedure 1. **Get the symbol.** Find a Yahoo ticker in the user's message (US: `AAPL`; Korean: `005930.KS` / `.KQ`; index: `^GSPC`). If there is none, ask. Handle several on
