Pipedream AI Steps: Add LLMs to Workflows for Free

Integrate an LLM into any Pipedream workflow in under five minutes, at zero cost.

Why Pipedream Is the Fastest Path to Free AI Automation

No servers, no infra, just a drag‑and‑drop step. You can call OpenAI, Anthropic, or Cohere directly from a pre‑built HTTP action.

Step‑by‑Step Guide to Adding an LLM

1. Open your Pipedream dashboard and click New Workflow. Choose a trigger (e.g., HTTP request or schedule).
2. Add a new step, select HTTP / Request, and paste the OpenAI endpoint URL: https://api.openai.com/v1/chat/completions.
3. In the Headers field, add:

   {
     "Content-Type": "application/json",
     "Authorization": "Bearer {{env.OPENAI_API_KEY}}"
   }

4. In the Body (JSON) field, supply the payload:

   {
     "model": "gpt-4o-mini",
     "messages": [
       {"role": "system", "content": "You are a helpful assistant."},
       {"role": "user", "content": "{{event.body.prompt}}"}
     ],
     "temperature": 0.7
   }

5. Save the step, then add a final Response action to return {{$json.choices[0].message.content}} to the caller.

Quick Reference
Copy this snippet into any Pipedream HTTP step to call OpenAI instantly.

{
  "model": "gpt-4o-mini",
  "messages": [{"role": "user", "content": "Your prompt here"}]
}

Using Other LLM Providers

Anthropic and Cohere work the same way—just change the endpoint and payload keys.

• Anthropic endpoint: https://api.anthropic.com/v1/messages
• Cohere endpoint: https://api.cohere.com/v1/chat

Do I need a credit card for OpenAI’s free tier?

OpenAI requires verification; you can use the $18 credit for testing.
