Auto-caption your posts with n8n + Caption-Pack (5 minutes, free)

说明与用途

通过8节点n8n工作流和免费Caption‑Pack API，您可以在五分钟内为X、LinkedIn和Instagram生成多平台内容计划，包括标题和标签，节省时间和成本。

问题

Creating platform‑specific captions for a single piece of content is time‑consuming and requires manual copy‑pasting.

结果

Within five minutes, users can generate multi‑platform caption plans for free, saving time and avoiding LLM costs.

工作流

• Get a free API key from https://caption-pack-api.onrender.com/v1/free-trial
• Import the caption‑pack‑n8n‑template.json workflow into n8n
• Create a Header Auth credential named Authorization with value "Bearer <key>"
• Assign the credential to the Call Caption‑Pack API and Check Balance nodes
• Run the workflow: fill the form with source content, audience, platforms, tone, and submit
• View the completion page showing per‑platform captions, hashtags, posting order, and remaining credits

证据

Last week I launched a small API that turns a topic, audience, and tone into ready‑to‑post social captions — no LLM in the loop, just a deterministic template‑and‑variant engine.
