Hello everyone,
When building AI automation workflows in n8n, testing different LLM models can quickly add up API costs — especially for indie builders, students and hobbyists.
I've curated a list of verified free API credits and limited trial tiers for major AI providers. You can leverage these free resources to prototype your n8n AI workflows before committing to paid API subscriptions.
👉 https://ai-credits.ai/free-api-credits
Simple workflow demo steps:
1. Grab your free API credits from the resource list
2. Open n8n and add HTTP Request node or native AI node
3. Input your API key and write your prompt
4. Run test for text generation, content summarization or lightweight AI agent workflows
This method helps you test ideas without spending money.
