use kimi2.5 api in claude code

[xiaozimu-code]

When I use ANTHROPIC_BASE_URL=https://api.moonshot.cn/anthropic and ANTHROPIC_MODEL=kimi-k2.5 to call Kimi 2.5 in Claude Code, I encounter the following error.
Does this indicate that Kimi's Anthropic-compatible interface does not support the document parameter? I did not find relevant information at https://platform.moonshot.cn/docs/overview.

error message:
API Error: 400 {"error":{"type":"invalid_request_error","message":"messages.8.content.4: Input tag 'document' found using 'type' does not match any of the expected tags: 'image', 'server_tool_use', 'text', 'thinking', 'tool_result', 'tool_use', 'web_search_tool_result'"},"request_id":"07b127d8-1e27-11f1-88f4-221de854e451","type":"error"}

ANTHROPIC_MODEL=moonshotai/kimi-k2.5
ANTHROPIC_BASE_URL=https://openrouter.ai/api

However, when using the OpenRouter interface, calls with type=document appear to work properly.

Try to upgrade claude code to the newest version (I am using 2.1.76 and everything goes well)

I am already using the latest version of Claude Code (verified via claude --version which returns 2.1.76), yet this issue persists. I believe the root cause is that the Kimi API is not compatible with the document parameter.

I think you are right. Seems like api.moonshot.cn/Anthropic/ does not support Claude code, while the Kimi code plan with URL:api.kimi.com/coding/ can be used in Claude code with subscription API Key.
