Request parameters

Name	Type	Required	Description
url	string	Yes	Public post/video/reel URL from one of 11 platforms: YouTube, TikTok, Instagram, Facebook, X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, or Rumble. Platform is auto-detected — cross-platform URLs are expected here (unlike single-platform endpoints). Not in scope: Kwai, Twitch, Spotify, Snapchat, and other Captapi platforms.
cache	boolean	No	Set true to serve from the 24h response cache (0 credits on hit). Default false — always fetch fresh. Envelope includes cached + cachedAt on hits.

Frequently asked questions

What does the Post Analytics API do?

The Post Analytics API lets you fetch full metadata and key stats from a public Utilities post or video URL using one GET request to /v1/analytics/post. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the Post Analytics 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 Utilities 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.

How is engagementRate calculated?

On Post Analytics and Compare, engagementRate is always interactions ÷ views (a ratio). Every metrics object includes engagementRateBasis: "interactions/views". TikTok popular-creators uses a different basis (Creative Center percent or avgLikesPerVideo/followers) — do not compare those numbers to post analytics without reading engagementRateBasis.

What do commentsIsApproximate / interactionsIsApproximate mean?

Some platforms expose compact UI counts (YouTube "2.4M" comments). We still return an integer, but commentsIsApproximate=true means that integer is rounded — interactions and engagementRate inherit the same uncertainty via interactionsIsApproximate. Prefer exact likes when present; do not treat interactions as unit-precise when the flag is true.

Which platforms are supported?

Eleven: YouTube, TikTok, Instagram, Facebook, X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, and Rumble. That is intentionally not the full Captapi catalog — Kwai, Twitch, Spotify, Snapchat, and others are out of scope for this unified metrics shape.

Is the Post Analytics 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.
