About this endpoint

`GET /v1/instagram/audio/{audioId}/reels` takes the numeric audio id from an Instagram audio page URL (for example the trailing digits in `https://www.instagram.com/reels/audio/1392969992841787/`). The response returns `data.audioId`, optional track-level `data.audio`, a `data.reels` array, and `data.page` (`hasMore`, `nextCursor`). Each reel row includes id, shortcode, url, caption, createdAt, thumbnail/display/video URLs, hasAudio, nested metrics, dimensions, owner, and when Instagram exposes them: `videoDurationSec`, location (including lat/lng), richer audio attribution, `taggedUsers`, and `coauthors`. Reel order is Instagram's audio-page ranking, not chronological. Pass optional `cursor` when `data.page.hasMore` is true.

`thumbnailUrl`, `displayUrl`, `videoUrl`, owner `avatarUrl`, and audio cover URLs are Instagram CDN links when present — they can expire or be rejected outside the original retrieval context. This route has no `lookupStatus`. An empty `data.reels` array can mean no public Reels use the audio, or other cases. Bill from `meta.creditsCharged`. For a creator's own Reels use `GET /v1/instagram/profiles/{handle}/reels`. For keyword discovery use `GET /v1/instagram/search/reels`. For a fresh trending sample use `GET /v1/instagram/reels/trending`.

Instagram audio Reels API FAQ

How do I list Instagram Reels for an audio track via API?

Call `GET /v1/instagram/audio/{audioId}/reels` with your Social Fetch API key (`x-api-key`) and the numeric audio id in the path. Read `data.reels` and `data.page` in the JSON response. See the API docs for parameters and examples.

Where do I get the Instagram audioId?

From a public Instagram audio page URL. The audioId is the numeric id in paths like `https://www.instagram.com/reels/audio/1392969992841787/`. You can also pull it from Reel payloads that include audio attribution when you already resolved a post.

How much does the Instagram audio Reels endpoint cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged — that field is the billing source of truth. Each paginated page is a separate billed request.

How does pagination work on Instagram audio Reels?

When `data.page.hasMore` is true, pass `data.page.nextCursor` as the `cursor` query param on the next request. Keep the same `audioId` across pages.

What does each audio-page reel row include?

The same product fields as trending Reels — id, shortcode, url, caption, createdAt, thumbnailUrl, displayUrl, videoUrl, hasAudio, nested metrics (plays, likes, comments), dimensions, and owner — plus videoDurationSec, location (id, name, lat/lng when present), audio attribution, taggedUsers, and coauthors when Instagram exposes them. `data.audio` is the track-level object for the requested audio id (artist, title, cover, duration, asset vs cluster id). Source CDN URLs can expire.

Are the Reels in chronological order?

No. Instagram ranks the audio page; `data.reels` follows that ranking, not `createdAt`. Sort client-side by `createdAt` if you need chronological order.

Why is data.reels empty for an audioId that looks valid?

This route has no `lookupStatus`. An empty array can mean no public Reels use this audio, or other cases. Do not treat an empty list as a hard "audio not found" signal without additional checks.

How is this different from profile Reels, keyword search, or trending?

This route pages Reels that reuse one audio id. `GET /v1/instagram/profiles/{handle}/reels` pages a creator's Reels tab by handle. `GET /v1/instagram/search/reels` is keyword discovery. `GET /v1/instagram/reels/trending` returns a fresh sample batch with no query. Use audio Reels when the sound is the join key for the list.

Do I need Instagram OAuth to list Reels for an audio track?

No. You authenticate to Social Fetch with an API key. The route reads public audio-page Reel data; it does not act on behalf of a logged-in Instagram user.
