Endpoints & Authentication

Base URLs

Endpoint	Base URL
Default	https://api.llmnex.com
Hong Kong acceleration	https://hk.llmnex.com

Examples use https://api.llmnex.com by default. To use Hong Kong acceleration, change only the base URL. Keep the API paths and authentication unchanged.

https://www.llmnex.com is the console for creating keys and reviewing usage and bills, not an API endpoint.

Operation	Method and path
List models	GET /v1/models
Generate images with Gemini	POST /v1beta/models/{model}:generateContent

Only Gemini models are currently supported. For direct HTTP calls, combine the base URL with the complete endpoint path.

For example, list models through the Hong Kong acceleration endpoint:

curl "https://hk.llmnex.com/v1/models" \
  -H "Authorization: Bearer YOUR_API_KEY"

Get an API Key

Create a token in the LLMNEX console. Keys look like sk-xxxxxxxx.

Keep your key private

Make requests from your server. Do not embed keys in frontend code or client apps. Replace the YOUR_API_KEY placeholder with your own key and never commit it to a repository.

Bearer Authentication

The model-list and image-generation examples use:

Authorization: Bearer YOUR_API_KEY

Gemini Authentication

Gemini endpoints also accept the following header. Use either this or Bearer authentication.

x-goog-api-key: YOUR_API_KEY

For endpoint-specific parameters and compatibility limits, see the Gemini Image Guide.
