Get started
Quickstart
Create an API key, select the correct protocol, and complete your first HopBase request.
Sign in to the console
Open api.hop-base.com/login and sign in with the account provided to you.
Create an API key
Open API Keys, select a plan group, and create a key beginning with sk-.
Configure the Base URL
Replace the API address in your tool or application with the matching HopBase Base URL, then provide the key.
Core settings
| Use case | Address |
|---|---|
| Anthropic protocol Claude Code and Claude models | https://api.hop-base.com |
| OpenAI protocol Codex, GPT, GLM, Gemini chat, and image models | https://api.hop-base.com/v1 |
| API key | sk-xxxxxx (created in the console) |
| Discover models available to the key | GET https://api.hop-base.com/v1/models |
The Anthropic Base URL does not include /v1; Anthropic clients append the API path. The OpenAI Base URL must include /v1.
Verify the key and model
Do not guess a model name. First fetch the list for the current key and select an ID that is actually present.
curl https://api.hop-base.com/v1/models \
-H "Authorization: Bearer sk-your-key"Then send a minimal request using a chat model returned above:
curl https://api.hop-base.com/v1/chat/completions \
-H "Authorization: Bearer sk-your-key" \
-H "Content-Type: application/json" \
-d '{
"model": "a-chat-model-returned-by-v1-models",
"messages": [{"role": "user", "content": "Reply with only: ok"}]
