TL;DR
SoundCloud track — plays/likes/license, nested artist{}, streamUrl when streamable (1 credit). The SoundCloud Track API (SoundCloud) is a single authenticated GET request to /v1/soundcloud/track that responds with clean JSON and costs 1 credit. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the SoundCloud Track API?

Pass a SoundCloud track URL and get clean JSON: title, artist{id,handle,name,url,avatar,followers,verified} (chain id/handle into /soundcloud/artist), plays/likes/reposts/comments/downloads, license, genre/tags, publishedAt, streamable/downloadable (SoundCloud permission flags), and when the public api-v2 allows it — streamUrl (progressive MP3), hlsUrl, downloadUrl, plus mediaUrlsExpireAt for signed CDN links. waveformUrl is the waveform JSON endpoint, not audio. Flat 1 credit. Accepts cache / cacheMaxAge.

What you get

  • Track fields as clean structured JSON
  • IDs, URLs, and titles where the platform exposes them
  • Engagement or popularity signals when available
  • Stable IDs for joining with other endpoints

Response structure

A successful call returns success, cached, creditsUsed, and a data object with the following fields:

Top-level fields

  • platformAlways "soundcloud" on this endpoint.
  • idStable platform ID for the item.

  • avatarAvatar / profile picture URL. Canonical across profile endpoints.
  • followersFollower count.
  • verifiedWhether the account is verified on this platform.

cachebooleanNoSet true to serve from the response cache (default TTL). Default false — always fetch fresh. Prefer cacheMaxAge when you need 1d–30d freshness control. Envelope includes cached + cachedAt on hits.
cacheMaxAgestringNoMax age of a cached response: 1d, 3d, 7d, 14d, or 30d. When set, enables caching with that TTL (SC cache_max_age). Envelope: cached + cachedAt.

Use cases

Engagement + license

Read plays/likes/reposts/comments/downloads and license for reuse research at 1 credit.

Playback URLs

Use streamUrl / hlsUrl (with mediaUrlsExpireAt) when streamable; downloadable is a permission flag.

Artist join

Chain artist.id or artist.handle into /soundcloud/artist without a second resolve scrape.

Frequently asked questions

What does the SoundCloud Track API do?+

The SoundCloud Track API lets you fetch full metadata and key stats from a public SoundCloud sound or track using one GET request to /v1/soundcloud/track. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the SoundCloud Track API cost?+

Each successful call costs 1 credit. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Failed or empty results are never charged.

Do I need a SoundCloud API key or OAuth?+

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.

What do streamable / downloadable mean if streamUrl is missing?+

They are SoundCloud permission flags on the track. When the public api-v2 lets us mint a progressive MP3 we return streamUrl (and often hlsUrl) with mediaUrlsExpireAt. downloadUrl is only present when SoundCloud exposes a public download without OAuth — downloadable:true alone does not guarantee a URL.

How do I join to soundcloud/artist?+

Use artist.id or artist.handle (permalink slug). artist.name/username-style display names can differ in casing from the URL slug.

Is the SoundCloud Track API suitable for production use?+

Yes. It is a stable REST endpoint with predictable JSON and automatic retries. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Use it for analytics, monitoring, and content automation.
