# Instagram Summarizer API

`GET /v1/instagram/summarize`

## Request

- Base URL: `https://api.captapi.com`
- URL: `https://api.captapi.com/v1/instagram/summarize`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-API-Key`

Get an AI summary of any Instagram Reel — a short paragraph plus key points, without watching the video.

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 infrastructure to maintain on your side. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh.
