  • Get Account Summary: View your credit balance, total savings, and referral code.
  • Check Low Credits: Check if your balance is below the warning threshold.

What data it sees

Do you need an account

No: the server works without sign-in

Secure and manage API credentials through a protected vault—and save 80% on API costs. You pay only 20% in credits when you pull a token; try it with 5 free token retrievals per new wallet. $10 deposit → $20 in credits; refer someone and when they deposit $10, you get $5. Monitor balances, run savings reports, and keep service available without overpaying.
