### \[1.0.0] — 2026-05-23

#### Added

- Initial release: complete YouTube SEO keyword research toolkit
- Three research modes: `keywordResearch` (single seed), `bulkKeywords` (batch), `seedVideoResearch` (auto-extract from video)
- 4 endpoint coverage: `/search`, `/suggest_queries`, `/related` (chained off top search result), `/hashtag`
- Unified tidy-long row schema with 6 `rowType` discriminators (`keyword_snapshot`, `search_result`, `suggestion`, `related_video`, `hashtag_trend`, `error`)
- Parallel endpoint fan-out per keyword with capped 3-keyword batch concurrency
- Predictable per-keyword headline pricing: 1 × `keyword-snapshot-result` anchor + per-row events for each endpoint
- Optional `region` / `language` biasing for non-US / non-English research
- Honest cross-sell positioning vs. our cheaper [autocomplete-only sibling actor](https://apify.com/sian.agency/youtube-auto-complete-and-query-suggestion?fpr=sian)
- HTML report saved to key-value store even on fatal crash
- Best-effort Telegram notification + telemetry sink
