Instagram Summarizer API

What is the Instagram Summarizer API?

Send a Reel URL and the Instagram Summarizer API transcribes the video and returns an AI-written summary as clean JSON: a concise paragraph plus a list of key points. Pass an optional language code (like 'tr') to pin the speech language and get the summary in that language — otherwise it auto-detects and summarizes in English. Perfect for content research at scale, briefing tools, and AI agents that need to understand video content without processing media. No Instagram login, no OAuth, and no proxies or infrastructure to maintain on your side. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh.

What you get

• 2–3 paragraph AI summary
• 4–8 bullet key points and detected topics
• Overall sentiment and tone
• Built on the transcript under the hood

Fill in the parameters below and copy a ready-to-run request, or open the live Playground to run it against your account (no API key paste).
