Introduction
Claudexia gives you Claude-compatible API access through one API key from the dashboard. It works with both the Anthropic Messages API and the OpenAI Chat Completions API, so you can plug it into SDKs, editors, agents, and automation tools that support a custom base URL.
What Claudexia provides
| Area | What you get |
|---|---|
| Anthropic-compatible | POST /v1/messages with Anthropic-style request and SSE streaming |
| OpenAI-compatible | POST /v1/chat/completions and GET /v1/models |
| Models | Claude (Opus 5.5, Sonnet 5, Haiku 4.5, Fable 5 and earlier versions), GPT-6 and GPT-5.6, Gemini, DeepSeek, Qwen, GLM, Grok, Kimi and MiniMax, plus image and video models |
| Tooling | Works with Claude Code, Claude Desktop, Codex, Cursor, VS Code, OpenCode, Zed, Hermes, OpenClaw, SDKs, and cURL |
| Billing | Pay-as-you-go per 1M tokens per model |
| Key controls | Name, Premium or Cheap channel, optional Premium fallback for Cheap, expiry, and usage statistics |
Recommended model IDs
These are the stable IDs we recommend in docs and clients:
claude-opus-5-5gpt-6-solclaude-sonnet-5gpt-6.1-solgpt-6-luna
Legacy dated Anthropic IDs and some aliases also resolve correctly, but for new setups it is better to use the stable names above.
Base URL rules
- Anthropic SDK / raw Anthropic API: use
https://api.claudexia.tech(without/v1) - OpenAI SDK / Cursor / VS Code OpenAI-compatible tools: use
https://api.claudexia.tech/v1 - Claude Code: use
https://api.claudexia.techforANTHROPIC_BASE_URL(without/v1)
The rendered docs will automatically replace the host above with whatever base URL is configured in admin settings.
