How to get Instagram post details

TL;DR
To get Instagram post details, sign up for a free Captapi key, then send one GET request to /v1/instagram/details with your input. You get clean JSON back in seconds for 1 credit per call — no OAuth, scraping or platform SDKs. Get an Instagram post or Reel — caption, likes, comments, media URLs, author, and publish date.

How to get Instagram post details (step by step)

    Get a free API key

    Create a free Captapi account (100 credits, no card) and generate an API key from the dashboard.

  2. 2

    Call the Instagram Post Details API

    Send an authenticated GET request to /v1/instagram/details with your input. No OAuth, no scraping setup.
