BeatAPI, Token Harbor and River keys

You can now add a BeatAPI, Token Harbor or River key under Dashboard → BYOK. AnyRouter charges nothing for a BYOK route; the provider bills you at its own rate. No new model ids: the keys add routes to models you already call, such as Claude, GPT-6, Grok, Kimi, GLM, Qwen, MiMo and DeepSeek.

Two of them have free DeepSeek V4.1 Flash variants. BeatAPI's deepseek-v4.1-flash-free allows one successful request per minute until your first top-up, then up to ten. Token Harbor's deepseek-v4.1-flash:free draws on a rolling 7-day free allowance once you turn on free models in its dashboard. River serves DeepSeek V4.1 Flash, its 1017 snapshot, Kimi K3, GLM-5.3, Qwen3.8 27B and Nemotron 3.5 Super VL.
