Claude Code

• Claude Code installed (`claude` on your PATH).
• An UplinkSwitch key from the console, with a balance loaded.

ANTHROPIC_API_KEY works in place of ANTHROPIC_AUTH_TOKEN. Set one, not both.

export ANTHROPIC_BASE_URL="https://api.uplinkswitch.com/v1"
export ANTHROPIC_AUTH_TOKEN="sk-uplink-live-..."
claude

Add them to ~/.claude/settings.json under env. The model variables take any id from the Models page.

{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.uplinkswitch.com/v1",
    "ANTHROPIC_AUTH_TOKEN": "sk-uplink-live-...",
    "ANTHROPIC_DEFAULT_OPUS_MODEL": "claude-opus-5-5",
    "ANTHROPIC_DEFAULT_SONNET_MODEL": "claude-sonnet-5-5",
    "ANTHROPIC_DEFAULT_HAIKU_MODEL": "claude-haiku-5-5"
  }
}

List the models your key can call:

curl https://api.uplinkswitch.com/v1/models -H "x-api-key: $ANTHROPIC_AUTH_TOKEN"

Then run claude. The request shows in the console within seconds.

• MCP tool search is off on a non-Anthropic host; ENABLE_TOOL_SEARCH=true turns it on.
• Prompt caching works; cached input bills at the cached rate.
• To switch back: unset ANTHROPIC_BASE_URL ANTHROPIC_AUTH_TOKEN.
