CreatorSignal API

Resource model

• Channel — a YouTube channel linked to your account. Ideas are submitted against a channel.
• Idea — a video idea with a title and category. Submitting an idea triggers AI validation.
• Validation — the AI research result for an idea. Contains a score (0-100), verdict (go/refine/kill), and a structured report.
• Webhook Endpoint — an HTTPS URL that receives validation events so you don't need to poll.
