Request parameters
| Name | Type | Required | Description |

| cache | boolean | No | Set true to serve from the 24h response cache (0 credits on hit). Default false — always fetch fresh. |
Frequently asked questions
What does the Facebook Post & Reel Details API do?
The Facebook Post & Reel Details API lets you fetch full metadata and key stats from a public Facebook post using one GET request to /v1/facebook/details. It returns clean JSON — no OAuth or infrastructure setup required.
How many credits does the Facebook Post & Reel Details API cost?
Each successful call costs 2 credits. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Failed or empty results are never charged.
Do I need a Facebook 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 access, rate limits, retries, and authentication for you.
Where did videoUrl go? The example used to have it.
Removed (FB-3). Playback is only on video{id, url, sdUrl, hdUrl, width, height, captionsUrl}. durationSeconds and thumbnailUrl stay on the post for cards. There is no flat videoUrl / videoSdUrl / videoHdUrl twin — data.videoUrl is undefined on every video.
Why is there no description? And why are views/shares missing on a photo?
description was a byte-identical copy of caption (the same GP-5 twin group-posts dropped). It is gone. views and shares are now always keyed — null on a photo, never omitted, never invented 0. likesIsApproximate / commentsIsApproximate / sharesIsApproximate / viewsIsApproximate ship on every 200.
What is feedbackId?
base64("feedback:" + id) when Facebook exposes it — the same token /facebook/comments accepts. Fully derivable from id; not extra information.
Can I paste a facebook.com/share/… link directly?
Yes. The Share button copies /share/<id>/ (or /share/p|r|v/<id>/). We resolve it for you: a cheap redirect first, then a full page render that reads Facebook's own og:url/canonical — logged-out Facebook stopped redirecting these links in 2026, so the render is what usually lands the reel or post. The mapping is cached 30 days, so pasting the same share link again is instant. You only see 400 UNRESOLVED_SHARE_LINK when Facebook refuses to reveal the canonical URL for that share token; then open the link in a browser and paste the resulting URL.
Is the Facebook Post & Reel Details 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. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Use it for analytics, monitoring, and content automation.
