Read TON and USDT wallet balance
Wallet balance API returns decimal strings for TON and USDT. Header mapping and precision-safe integration examples.
Purchase requests transmit your wallet mnemonic and Fragment session/cookie to the API operator.
GET /wallet-balance/ needs Mnemonic, but not Cookie. Wallet-Version, Wallet-Address, and TonConsole Api-Key are optional. The inspected backend also accepts POST; SDK convenience methods use GET.
Keep ton and usdt_ton as strings or arbitrary-precision decimal values. Converting a balance such as 9007199254740993.01 to a JavaScript Number loses precision. This read operation still discloses the submitted mnemonic to the API operator.
Example
curl https://fragment.donor.uz/wallet-balance/ \
-H "Mnemonic: $WALLET_MNEMONIC" -H "Wallet-Version: auto"Response
