Claude API integration docs for CoreNode
This page is a crawlable documentation surface for CoreNode. It gives search engines and developers a stable reference for the base URL, auth format, and the first request to make.
Authorization
Authorization: Bearer YOUR_API_KEY
/v1/models
Query this endpoint first to confirm which Claude models are visible to your account before you send production traffic.
/v1/chat/completions
OpenAI-compatible chat completions endpoint for most existing SDK integrations and internal tools.
Working curl example
curl https://api.corenode.best/v1/chat/completions \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"claude-sonnet-4-5-20250929","messages":[{"role":"user","content":"Hello"}]}'1
Create an API key in the CoreNode console.
2
Replace your base URL with https://api.corenode.best/v1.
3
Call /v1/models first, then switch to the Claude model you want to use.
How do I connect an existing project?
Create an API key in the console, switch your base URL to https://api.corenode.best/v1, and keep your OpenAI-compatible request flow intact.
Why call /v1/models first?
It shows the exact model names visible to your account, which makes validation and debugging much faster before real traffic starts.
What clients are supported?
CoreNode works with OpenAI SDK clients, Claude Code, CC Switch, and direct HTTP integrations that expect a standard API endpoint.
