TL;DR
Give it an Instagram sound and get back every Reel that uses it — each with its video, caption, creator, and view / like / comment counts. The Instagram Reels By Audio ID API (Instagram) is a single authenticated GET request to /v1/instagram/reels-by-audio-id that responds with clean JSON and costs ~28 credits (1.4/result). Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the Instagram Reels By Audio ID API?

On Instagram every Reel is built on an audio track, and each track has its own page listing the Reels that use it. This API takes that sound — either the numeric audio ID (the musicId you see on a Reel) or a full audio-page URL like https://www.instagram.com/reels/audio/AUDIO_ID/ — and returns those Reels as clean JSON. For each Reel you get a direct video URL, caption, the creator's profile, play / like / comment counts, duration, and publish date. Use it to see how far a trending sound has spread, find every creator who used your music, or measure a branded-audio campaign. No Instagram login, no OAuth, and no infrastructure to maintain. Pass cache=true to serve from the 24h shared cache (0 credits on hit); default is always fresh.

What you get

  • Every public Reel made with that audio track
  • Direct MP4 video URL and thumbnail for each Reel
  • Caption, duration, publish date, and the sound's audio ID
  • Creator handle plus play / like / comment counts
