Channel intelligence without an API key

Inspect public channel identity, visible subscribers, video totals, lifetime views, and a limited recent-upload window without an API key. The Python standard-library helper fetches channel pages and a public upload feed, uses regex to locate embedded objects, and decodes structured data without brittle brace matching. Missing or localized fields remain unknown, abbreviated counts retain their source text, and partial results include warnings. An offline mode and fixtures support parser maintenance when page layouts change. The monitoring playbook covers stable channel IDs, timestamped snapshots, peer selection, age-matched comparisons, and an optional Data API upgrade path. This is public research tooling, not private creator analytics or an automated growth diagnosis.
