Get $200 Free AI API Credits (Azure Foundry Hack) + Use GPT/Gemini in n8n for $0
Most businesses waste hundreds monthly on AI API credits just to test automation ideas. Microsoft Azure's little-known Foundry program gives you $200 in free credits to access GPT-5.2, Gemini, and other premium models - with no ongoing costs. Here's how to deploy these in n8n workflows without touching your credit card after initial setup.
The $200 Azure Free Credit Hack
AI API costs add up fast - most providers require $5+ deposits just to test their models. At 92 rupees per dollar, that's nearly 500 rupees per API just for experimentation. Microsoft Azure's AI Foundry program breaks this barrier by offering $200 in completely free credits.
Here's how it works: When you create a new Azure account, you get:
- $200 credit valid for 30 days
- Access to Azure-hosted models (GPT-5.2, Gemini, Deepseek, etc.)
- No charges unless you explicitly upgrade to paid
Key requirement: You'll need a credit/debit card with international transactions enabled for verification, but Microsoft won't charge it unless you manually switch to pay-as-you-go after consuming the free credits.
What Models You Can (And Can't) Access
Not all AI models are available through the free credits. Azure distinguishes between:
- Azure-hosted models (eligible): GPT-5.2, Gemini, Deepseek V3.2 - marked "direct from Azure"
- Provider-direct models (ineligible): Claude 4.5, Perplexity - require pay-as-you-go
At 6:45 in the video, you'll see how to identify eligible models in the Azure portal. The key is looking for the "direct from Azure" label in the model catalog.
Connecting Azure AI to n8n
The magic happens when you connect these free credits to n8n. Here's the step-by-step:
- Create a Microsoft Foundry resource in Azure
- Deploy your chosen model (e.g., GPT-40-mini)
- Grab the API key, endpoint URL, and resource name
- In n8n, use either:
- HTTP Request node for direct API calls
- AI Agent node with Azure OpenAI configuration
Pro Tip: Always delete test deployments when done. Azure doesn't automatically clean up resources, which could lead to unexpected charges if you exceed credits.
Critical API Parameter Differences
At 12:30 in the tutorial, we hit a major revelation: Azure's API requires different parameters than standard OpenAI calls. For "thinking" models like GPT-5.2:
- Replace
"messages"with"input" - Change
"max_completion_tokens"to"max_output_tokens"
This explains why the official Microsoft documentation sometimes fails - their examples often use the wrong parameter names for certain model types.
Configuring n8n AI Agents
For n8n's AI Agent node (shown at 14:45):
- Select "Azure OpenAI Chat Model"
- Input:
- API key from Azure portal
- Resource name (e.g., "gpt-40-mini")
- Endpoint URL
- API version (usually "2023-05-15")
This configuration lets you use Azure's free credits while maintaining the simplicity of n8n's AI Agent interface.
Monitoring Your Free Credits
Azure's credit system has two critical monitoring points:
- Credit balance: Visible in the Azure portal dashboard
- Expiration date: 30 days from account creation
For ongoing projects, you can create multiple Azure accounts with different emails to extend the free credits. Just be sure to:
- Delete all resources before credits expire
- Use separate cards or virtual cards for each account
- Track usage carefully to avoid surprise charges
Production Use Considerations
While perfect for testing, the free credits have limitations for production:
- 30-day expiration isn't reliable for long-term workflows
- Account creation process doesn't scale
- Some enterprise features require paid plans
For business-critical automation, Azure's pay-as-you-go plans start at $0.0004 per token for smaller models - often cheaper than direct provider pricing.

Key Takeaways
Microsoft's Azure Foundry program is the most underutilized resource for AI automation testing. By combining the $200 free credits with n8n's flexibility, you can:
- Test premium AI models without upfront costs
- Build proof-of-concept workflows risk-free
- Learn API integration with real models
In summary: Azure's free credits remove the financial barrier to AI automation experimentation, while n8n provides the tools to turn those experiments into business value.
Frequently Asked Questions
Common questions about this topic
The Azure Foundry program gives you access to models like GPT-5.2, Gemini, Deepseek V3.2, and other Azure-hosted models. Flagship models from providers like Anthropic (Claude) require pay-as-you-go plans.
You'll want to look for models marked "direct from Azure" in the catalog. These are fully covered by your free credits without additional provider requirements.
- Eligible: GPT-5.2, Gemini, Deepseek V3.2
- Ineligible: Claude 4.5, Perplexity, provider-direct models
- Always check the model details for "direct from Azure" label
Yes, you'll need a credit or debit card with international transactions enabled for initial verification. Microsoft requires this to prevent abuse of their free tier.
The good news: They won't charge your card unless you explicitly upgrade to a paid plan after using the $200 credits. The card is purely for identity verification.
- Virtual cards work if your bank offers them
- Prepaid cards may not be accepted
- No charges unless you manually switch to paid
The $200 in credits are valid for 30 days from account creation. Azure designed this as a trial period rather than an ongoing free tier.
For ongoing projects, you can create new Azure accounts with new email addresses to continue accessing free credits. Just be sure to delete resources when done to avoid unexpected charges.
- 30-day expiration from account creation
- Multiple accounts strategy works for testing
- Always monitor usage in Azure portal
Some Azure models require different API parameters than standard OpenAI models. This is especially true for "thinking" models versus "instant answer" models.
For models like GPT-5.2, you need to replace "messages" with "input" and "max_completion_tokens" with "max_output_tokens" in your API calls. The video at 12:30 shows the exact JSON formatting needed.
- Parameter names vary by model type
- Azure's documentation sometimes shows wrong examples
- HTTP Request node gives more control than AI Agent
While technically possible, we don't recommend relying solely on free credits for production workflows. The 30-day limit and account creation process make it unreliable for business operations.
For business-critical automation, consider Azure's pay-as-you-go plans starting at $0.0004 per token for smaller models. This provides stability while still being cost-effective.
- Free tier not designed for production
- Pay-as-you-go starts at $0.0004/token
- Enterprise plans offer better rate limits
The main limitations are the 30-day expiration and inability to access some flagship models. Azure also requires careful resource management to avoid accidental charges.
However, for testing and development, it's an unbeatable way to access premium AI capabilities. Just be diligent about deleting unused resources and monitoring your credit balance.
- 30-day expiration
- Some models unavailable
- Manual resource cleanup required
In n8n, use the HTTP Request node to call Azure's REST API endpoints. For AI Agents, select "Azure OpenAI Chat Model" and input your API key, resource name (like 'gpt-40-mini'), and endpoint URL from the Azure portal.
The video demonstrates full setup at 14:45, including the critical configuration details that Microsoft's documentation often misses. Pay special attention to the API version and deployment name fields.
