n8n-nodes-captapi
This is an n8n community node. It lets you use Captapi in your n8n workflows.
Captapi turns public social URLs into clean, structured JSON — transcripts, AI summaries, comments, video/post details, profile & channel stats, search, commerce data, ad libraries, downloads, and account usage. One API key, 178 operations across 32 platforms.

Installation
Follow the community nodes installation guide in the n8n docs.
In your n8n instance:
- Go to Settings → Community Nodes.
- Select Install.
- Enter
n8n-nodes-captapias the npm package name. - Agree to the risks and select Install.
The Captapi node and Captapi API credential will then be available.
Credentials
You need a Captapi API key:
- Create a free account at captapi.com.
- Open Dashboard → API Keys and copy a key.
- In n8n, create a new Captapi API credential and paste the key.
The credential test calls GET /v1/account/limits (plan quotas + remaining credits). That route is live on the API; it is an auth ping, not one of the 178 catalogued operations. Base URL defaults to https://api.captapi.com and rarely needs changing.
Operations
Pick a Platform, then an Operation. Every operation maps 1:1 to a Captapi REST endpoint and exposes that endpoint's inputs (URL, Query, Limit, …). Limit defaults and maxima match the live API (for example Facebook Profile Posts is default 4 / max 4 — not 200).

Pricing is credit-based. Many list endpoints are a flat fee per call; a few still scale with results. Cached responses are free (except where the endpoint says cache hits still bill) and failed or empty results are never charged. See captapi.com/pricing.
