Claude Code

Claude Code talks to the Anthropic Messages API, so it works against LETHE’s Messages API with just environment variables, no code changes.

.env

export ANTHROPIC_BASE_URL="https://asklethe.ai"
export ANTHROPIC_AUTH_TOKEN="$LETHE_API_KEY"
export ANTHROPIC_DEFAULT_OPUS_MODEL="lethe"
export ANTHROPIC_DEFAULT_SONNET_MODEL="lethe"
export ANTHROPIC_DEFAULT_HAIKU_MODEL="lethe"

Get $LETHE_API_KEY from Authentication. Claude Code’s default model picker ids (opus, sonnet, haiku) are automatically aliased to lethe server-side, so setting all three env vars to lethe is intentional, not a placeholder.
