TTAPI’s Claude-compatible base URL is https://cc.ttapi.io. Once your local environment variables are set, Claude Code will send requests through TTAPI.
1. Install
irm https://claude.ai/install.ps1 | iex
claude is still not found after installation, reopen your terminal so the updated PATH can take effect.2. Verify
Set the variables for the current session:$env:ANTHROPIC_BASE_URL = "https://cc.ttapi.io"
$env:ANTHROPIC_API_KEY = "YOUR-TT-API-KEY"
[Environment]::SetEnvironmentVariable("ANTHROPIC_BASE_URL", "https://cc.ttapi.io", "User")
[Environment]::SetEnvironmentVariable("ANTHROPIC_API_KEY", "YOUR-TT-API-KEY", "User")
4. Start
1. Install
Official install script:curl -fsSL https://claude.ai/install.sh | bash
brew install --cask claude-code
2. Verify

export ANTHROPIC_API_KEY="YOUR-TT-API-KEY"
~/.zshrc or ~/.bashrc if you want them to persist across sessions.4. Start
Notes
- Script installs usually update automatically
- Homebrew installs require manual upgrades such as
brew upgrade claude-code
1. Install
curl -fsSL https://claude.ai/install.sh | bash
2. Verify

Required environment variables
ANTHROPIC_BASE_URL=https://cc.ttapi.io
ANTHROPIC_API_KEY=YOUR-TT-API-KEY
Troubleshooting
claude command not found
- Reopen the terminal
- Confirm the install path is on
PATH
- Run
claude --version again
Auth or request error after launch
- Check that
ANTHROPIC_BASE_URL is set to https://cc.ttapi.io
- Check that
ANTHROPIC_API_KEY contains a valid TTAPI key
- Reopen the terminal to reload environment variables
Can I still use the default Anthropic setup?
Yes. But if you want Claude Code traffic to go through TTAPI, both ANTHROPIC_BASE_URL and ANTHROPIC_API_KEY must point to the TTAPI-compatible endpoint and your TTAPI key.
