Codex CLI / Codex App
Codex supports two wire protocols: responses and
chat. Choose based on model capability. Once
~/.codex/config.toml and XAI_API_KEY
are configured, Codex App can reuse the same gateway setup. On
Windows, the config path is
%USERPROFILE%\.codex\config.toml.

Claude Code (MiniMax-M2.5)
Claude Code integration is primarily environment-variable based.
The following example sets MiniMax-M2.5 as the
default model family via
export XAI_API_KEY="sk-Xvs..."
export ANTHROPIC_AUTH_TOKEN="$XAI_API_KEY"
export ANTHROPIC_BASE_URL=""
# Optional: custom default model mapping for Claude families (not required)
export ANTHROPIC_DEFAULT_OPUS_MODEL="MiniMax-M2.5"
export ANTHROPIC_DEFAULT_SONNET_MODEL="MiniMax-M2.5"
export ANTHROPIC_DEFAULT_HAIKU_MODEL="MiniMax-M2.5"
# launch Claude Code

OpenCode (MiniMax-M2.5)
OpenCode connects through the OpenAI API endpoint. Put core setup
in ~/.config/opencode/opencode.json (on Windows, you
can use %USERPROFILE%\.config\opencode\opencode.json),
and set XAI_API_KEY. OpenAI API has two request formats:
Chat Completions (/v1/chat/completions) and
Responses (/v1/responses).

OpenClaw
OpenClaw can connect to OpenAI API and Claude API, and can also
be extended to OpenAI Responses API. XAI Router supports OpenAI
API and Claude API by default; for Responses mode,
set api = "openai-responses". Config path:
~/.openclaw/openclaw.json on Linux / macOS, and
%USERPROFILE%\.openclaw\openclaw.json on Windows.
