Solo Router

Solo Router gives developers access to multiple AI models through one API key and prepaid balance. Its chat-completions API supports models from DeepSeek, GLM, Kimi, Qwen, Llama, Gemma and other providers. It also offers image, video, speech, music, embedding and reranking endpoints, plus browser-based chat. Developers can switch models by changing the model name, use streaming and tool calling, and set spending limits per key. Usage is billed from prepaid credits with visible per-model prices and no subscription. Free starter credit is available; paid top-ups start at US$5.
