## FAQ

### Can I test the server for free?

Yes, you can use a test key which returns fixed answers and is never billed. You can also use a public sandbox key for limited testing.

### Does the server provide personal information from email checks?

No, email checks only return whether the account exists (yes, no, or unknown) and never provide names or profiles.

### How does the server prevent excessive spending?

The server performs a free cost estimate before any billed tool runs and will refuse the call if the cost exceeds a specified threshold.

### What kind of phone number information can be retrieved?

You can check registration on WhatsApp, Telegram, Viber, and Signal, as well as carrier, line type, and spam reputation.
