Overview
Kimi K3 on KeyoAPI is the Moonshot-family chat model exposed as kimi-k3 (token-metered) and kimi-k3-free (permanent $0 fair-use). Indicative paid rates are about $7.50 / $37.50 per 1M in/out — confirm live on /pricing/kimi-k3. This page is intentionally short. Search demand for kimi k3 api is near zero, so we prioritize accurate IDs, a Free tier block, and links into /free-models plus stronger family pages like /model/glm-5.2 and /deepseek-api-pricing. Use the OpenAI-compatible base URL https://www.keyoapi.xyz/v1, set Authorization: Bearer YOUR_KEY, and pick the free or paid model string. Fair-use limits apply on free. For production QPS, prefer paid kimi-k3 or another Keyo chat model that fits your latency budget.
