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

Описание и применение

Автоматизированный рецепт на n8n использует API без LLM для генерации структурированных подписей к постам, экономя время и деньги.

Задача

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

Результат

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

Рабочий процесс

• 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

Доказательства

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

Источник

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.

Источник

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