The Claude API is Anthropic's programmatic interface for accessing Claude, a large language model designed for helpful, harmless, and honest AI assistance. VidNo uses the Claude API specifically for its script generation stage — the step where raw technical context (OCR-extracted code, git diffs, detected tools and frameworks) is transformed into a coherent, engaging video narration. Claude excels at this task because of its large context window, which can process an entire coding session's worth of extracted data in a single request, and its ability to produce technically accurate explanations that maintain a conversational, tutorial-like tone. The API call sends only text-based summaries and code context — never raw video files or screen captures. This keeps API costs predictable and data transmission minimal. Each video script typically requires one or two API calls, costing a few cents per video depending on session length. VidNo handles API key management, request formatting, and response parsing automatically as part of the pipeline.
