Claude Code with idapt

Three environment variables route Claude Code through idapt, with per-key spend caps on top.

1. 1

   Install

   bash

   curl -fsSL https://claude.ai/install.sh | bash

2. 2

   Point it at idapt

   bash

   export ANTHROPIC_BASE_URL="https://idapt.app/api/anthropic"
   export ANTHROPIC_AUTH_TOKEN="$IDAPT_API_KEY"
   export ANTHROPIC_API_KEY=""
   claude

   Add these to your shell profile so every session picks them up. The base URL has no /v1: Claude Code appends /v1/messages itself.

3. 3

   Going further

   bash

   # Optional: pin models per task class, then confirm with /model
   export ANTHROPIC_DEFAULT_SONNET_MODEL="anthropic/claude-sonnet-5"
   export CLAUDE_CODE_SUBAGENT_MODEL="anthropic/claude-sonnet-5"
   export CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1

   Discovery populates the /model picker from the gateway. Pin the other classes (OPUS, HAIKU, FABLE) the same way.
