How it works

Set up in 5 minutes, not 5 days.

No SDK to install. No code refactor. One URL change and MarginAI captures everything.

01
Change your base URL
Point your OpenAI or Anthropic client at MarginAI. Your real API key passes through unchanged.
// Before baseURL: "https://api.openai.com/v1" // After baseURL: "https://www.aimargin.net/v1/openai"
02
Tag your client
Add two headers to every request to attribute it to a client. That's the entire integration.
"x-marginai-agency": "my-agency" "x-marginai-client": "acme-corp"
03
See costs in real time
Your dashboard instantly shows cost per client, margin, daily spend, and model breakdown. No configuration needed.
04
Send white-label reports
Generate a branded PDF showing your client's AI usage, cost, and value delivered. One click, every month.

Features

Built for agencies. Not engineering teams.

Every tool we built is for the person who bills clients — not the developer who writes the code.
