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.

Website:

• English: https://ai-router.dev
• 中文: https://ai-router.dev/cn
• Русский: https://ai-router.dev/ru
• فارسی: https://ai-router.dev/fa

API endpoint:

https://api.ai-router.dev/v1

Examples

Runtime	File
curl	examples/curl/chat-completions.sh
Python	examples/python/chat_completion.py
Node.js	examples/nodejs/chat_completion.mjs

Quick start

Set your API key and choose a model available to that key:

export AI_ROUTER_API_KEY="replace_with_your_api_key"
export AI_ROUTER_MODEL="model_id_from_your_dashboard_or_models_response"

With an authenticated API key, you can list the model IDs available to it:

curl -sS https://api.ai-router.dev/v1/models \
  -H "Authorization: Bearer $AI_ROUTER_API_KEY"

Copy an id from the response into AI_ROUTER_MODEL. The available catalog can vary by API key, account configuration, and time; the dashboard is an equivalent source of the current model ID.

Call the OpenAI-compatible chat completions endpoint:

curl https://api.ai-router.dev/v1/chat/completions \
  -H "Authorization: Bearer $AI_ROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  --data-binary @- <<JSON
  {
    "model": "$AI_ROUTER_MODEL",
    "messages": [
      { "role": "user", "content": "Write one sentence about OpenAI-compatible APIs." }
    ]
  }
JSON

Use the model name returned by /v1/models or shown in your AI ROUTER dashboard.
