RouterPlex is a multi-model API with both OpenAI-compatible and Anthropic-compatible request formats. One key, one balance — every model we serve, from GPT and Claude to Gemini, DeepSeek, Kimi and Qwen.
OpenAI base URL: https://api.routerplex.com/v1
>
Anthropic base URL: https://api.routerplex.com — the Anthropic SDK appends /v1/messages.
How it works #
- You create an API key in the dashboard.
- You point any OpenAI-compatible SDK, IDE, or agent at
https://api.routerplex.com/v1. - You pick a model by its ID (for example
gpt-5.5,claude-opus-4-8,gemini-3.1-pro) — same request shape for all of them. - Every request deducts its exact token cost from your prepaid balance. No subscription required.
