n8n Anthropic Claude Workflow: 3 Short Video Ideas (JSON)

Generate 3 short video ideas with Claude—validated as strict JSON in n8n

Need fresh, audience-specific short-form video concepts fast? This n8n Anthropic Claude Workflow takes your topic, target audience, and Claude model, then returns exactly three ready-to-plan video ideas—each with a hook, angle, and one-sentence outline in strict JSON.

What this workflow does

• Runs manually when you execute it in n8n (via a manual trigger).
• Uses your input values for topic, audience, and the Claude model to generate content.
• Builds a single Anthropic Messages API request with a system prompt that requires the model to return exactly three ideas as a JSON object.
• Sends the request using an HTTP Request node to Anthropic’s API.
• Parses and validates the response to ensure it is valid JSON and contains exactly three ideas with the expected fields (hook, angle, one-sentence outline).
• Outputs three separate n8n items—one per idea—so you can copy them directly into your content planner.

Use cases

• Content teams who need three short video concepts for a campaign based on a specific audience.
• SaaS operators iterating quickly on marketing angles for a product topic.
• Automation engineers testing Claude-to-JSON generation and response validation inside n8n.
