Frequently asked questions
What does the Compare Analytics API do?
The Compare 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/compare. It returns clean JSON — no OAuth or infrastructure setup required.
How many credits does the Compare Analytics API cost?
Billing is 1 credit per successfully resolved URL that is not served from cache. Cache hits (cache=true) are free, same as Post Analytics. Failed URLs appear in failed[] and are not billed. There is no bulk discount vs calling /v1/analytics/post once per URL — compare saves HTTP round-trips. A fully failed batch still records a minimal 1-credit charge.
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.
What happens when some URLs fail?
Each results[] row has status ok or error and a platform field when detected. Failed URLs also appear in failed[] as {url, platform, reason}. Only successfully resolved URLs are billed (1 credit each; cache hits free).
Is each results[] row the same as Post Analytics?
Yes — the same mapper and schema (platform, id, title, url, publishedAt, durationSeconds, thumbnailUrl, author{}, metrics{}), plus status. publishedAt is full ISO with milliseconds on both endpoints.
Is the Compare 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.
