Use Mimxo AI as the API provider for Claude Code
Claude Code speaks the Anthropic Messages API. Mimxo AI serves it natively at /v1/messages, including streaming, so you only set two environment variables.
1. Create a key
Sign up at mimxo.com, top up and create a key.
2. Point Claude Code at Mimxo AI
export ANTHROPIC_BASE_URL="https://mimxo.com" export ANTHROPIC_AUTH_TOKEN="sk-your-mimxo-key" export ANTHROPIC_MODEL="claude-sonnet-5" export ANTHROPIC_SMALL_FAST_MODEL="claude-sonnet-5" export ANTHROPIC_DEFAULT_HAIKU_MODEL="claude-sonnet-5" claude
Or put the same keys in ~/.claude/settings.json under "env". Use claude-opus-5 as ANTHROPIC_MODEL for harder work.
3. Check it
curl https://mimxo.com/v1/messages \
-H "x-api-key: $ANTHROPIC_AUTH_TOKEN" -H "anthropic-version: 2023-06-01" \
-H "Content-Type: application/json" \
