Useful results.
Honest uncertainty.

Discovery is free.

initialize and tools/list do not spend project credits. Known free and disposable domain checks are free too.

Projects stay isolated.

The server resolves the project from its API key. Clients never send or choose a project ID.

No guessing.

If a reliable answer is not available, the result is unknown.
