The Moonshot AI (Kimi) API serves the Kimi K-series at api.moonshot.ai. It exposes OpenAI-compatible
Chat Completions (/v1/chat/completions), OpenAI Responses (/v1/responses) and an Anthropic-compatible
Messages endpoint (/anthropic/v1/messages), plus files, batches, tokenizer and web-search tools.
Streaming is SSE with separate reasoning_content and content deltas. kimi-k3 uses top-level reasoning_effort (low/high/max, default max); K2.x models use the thinking parameter. JSON mode / structured output, automatic context caching and file upload (text/image/video) are supported. Temperature and top_p are fixed for K3 and K2.x. Serving regions are not stated in the fetched docs.
