## Changelog

### 0.1 — 2026-11-02

- Initial release.
- Modes: `events` (default; grouped events with nested child markets) and `markets` (one market per row).
- Fields: implied probability, Yes/No bid-ask, last price, previous price and price change, volume (total/24h), open interest, status, open/close times; events add category, series, settlement sources and nested markets.
- Filters: `status` (open/closed/settled/unopened), `seriesTicker`, `minVolume` (markets mode, transparent — scanned count reported), `maxResults`. Cursor pagination.
- Source: Kalshi public trade API via Apify datacenter proxy (undici with a hard overall-deadline AbortController; got-scraping hangs behind the proxy). Market data is keyless; only placing orders needs auth, which this never does. `/series` (~19 MB) is not used.
- Pay-per-event billing: `market` $0.002, `event` $0.004. No charge for errors or empty runs.
- Standby API implemented (same `collect()`); published as batch for now.
