ChatGPT API Relay Examples

OpenAI-compatible ChatGPT API relay examples for AI ROUTER.

AI ROUTER lets developers call ChatGPT-style models through an OpenAI-compatible endpoint, manage API keys, and check usage, quota, balance, and subscription status from the dashboard.

Quick start

Set your API key:

export AI_ROUTER_API_KEY="replace_with_your_api_key"

Call the OpenAI-compatible chat completions endpoint:

curl https://api.ai-router.dev/v1/chat/completions \
  -H "Authorization: Bearer $AI_ROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.4-mini",
    "messages": [
      { "role": "user", "content": "Write one sentence about OpenAI-compatible APIs." }
    ]
  }'

Use the model name shown in your AI ROUTER dashboard. The example uses gpt-5.4-mini as a low-cost default.
