I wired a no-LLM captions API into n8n — here's the free template

说明与用途

在 n8n 中使用无 LLM 的确定性字幕生成 API 的自动化流程，节省时间和成本。

问题

Writing social captions manually is time‑consuming and costly when using LLMs for each post.

结果

The workflow costs exactly one credit per run, regardless of caption count, and failed calls do not consume credits.

工作流

• Fill form trigger with topic, audience, tone, platform, and count
• HTTP Request node calls POST /v1/caption-pack with API key
• Code node formats returned pack and shows credit balance
• Form ending node displays captions for copy and posting

证据

Every social post I write used to start the same way: stare at a blank caption box, burn five minutes, write something mid.

来源

I built a small API that generates captions deterministically — template-and-variant engine, no LLM anywhere near it — and then I wired it into n8n so the whole thing runs hands‑off.

Each run costs exactly 1 credit, no matter how many captions you request. Failed calls never cost credits.

Free 25 credits (no card) → $10 for 500. One Stripe click. No subscription.
