The API returns JSON data including full transcripts with timestamps, video metadata, and optional Claude-generated summaries through a single REST call. It handles caption parsing, Whisper fallback for videos without captions, and rate limiting automatically.", "body_md": "YouTube is the world's largest knowledge base. Billions of hours of tutorials, lectures, interviews, and technical walkthroughs — and your AI agent can't touch any of it.\n\nIt can read text. It can search the web. But it can't watch a video.\n\nI built TubeScribe API to fix that.\n\nWhen you're building an AI agent or RAG pipeline, you constantly run into this wall. A user asks \"summarize this YouTube video\" or \"extract the key points from this lecture\" — and you have nothing. The transcript might be buried in auto-generated captions, or not exist at all for older videos.\n\nYou could build your own solution. Pull the Innertube API, parse the caption XML, handle Whisper fallback for videos with no captions, deal with rate limits and format variations... or you could just make one API call.\n\n```\ncurl \"https://transcriptapi.dev/transcript?url=https://youtube.com/watch?v=VIDEO_ID&summary=true\" \\\n  -H \"X-API-Key: your_key\"\n```\n\nResponse:\n\n```\n{\n  \"title\": \"...\",\n  \"channel\": \"...\",\n  \"duration\": 1247,\n  \"transcript\": [\n    { \"text\": \"Welcome back everyone...\", \"start\": 0.0, \"duration\": 3.2 },\n    ...\n  ],\n  \"summary\": \"This video covers...\",\n  \"wordCount\": 4821,\n  \"cached\": false\n}\n```\n\nThat's it. Full transcript with timestamps, video metadata, and an optional Claude AI summary — all in one response.\n\n`&summary=true`\n\nand get a structured summary generated by Claude alongside the raw transcript.The API is built for developers and AI agents. JSON responses, standard REST, straightforward auth via `X-API-Key`\n\nheader.\n\nOpenAPI spec available at [transcriptapi.dev/openapi.yaml](https://transcriptapi.dev/openapi.yaml) if you want to import it directly into Postman, Insomnia, or your agent framework.\n\nIf you're building anything with AI + video content, I'd love to hear what you're working on.
