Can't be undone 1Claude Code: ask
  • topup_creditsPaid (the amount you choose, minimum $1).No findings

    Why it is in this group

    • The name "topup_credits" says "topup": a word that usually means money moves, which cannot be taken back.
    • The description says "cannot be recovered".
    Description, as the server wrote it
    Paid (the amount you choose, minimum $1). Buy prepaid credits with x402 so later calls skip the per-call payment round trip. With an Authorization: Bearer bby_live_... header on this connection it recharges that key. Without one, the paying wallet becomes the account and a new API key is minted and returned once — store it as a secret, it cannot be recovered.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
