Does this use claude login oauth or API key costs?

[ariel-frischer]

Github copilot says: OAuth (e.g., standard Claude OAuth login) is NOT the primary authentication method. I also received an API bill when I was running the swarm so I do believe it overrides my normal oauth flow? Do i need to set ANTHROPIC_API_KEY="" before running it to have claude default to oauth login?

The command I used was:

npx claude-flow@alpha swarm "build REST API with authentication" --claude

If your ANTHROPIC_API_KEY is defined in the environment, claude-flow prioritizes that over OAuth, which is why you got billed. Just remove or unset the key (e.g. unset ANTHROPIC_API_KEY on macOS/Linux or set ANTHROPIC_API_KEY= on Windows) before running the swarm, and it’ll use OAuth login instead.
