Business API key for server-to-server integrations.
Key prefix determines the environment — no separate flag needed:
test_sk_* = sandbox/testnet, live_sk_* = production/mainnet.
Path Parameters
Body
Amount to transfer as a string. By default this is a HUMAN-READABLE coin amount — "2.5" = 2.5 coins, "100" = 100 coins (a bare integer and a decimal mean the same thing). Set unit: "base" to instead pass a pre-converted integer in the smallest unit (wei/satoshi/lamport/drop). Must be positive; zero, negative, or unparseable values return 400.
"2.5"
"USDT"
BTC, BCH, LTC, BSC, ETH, POL, TRX, SOL, XRP, BASE, ARB, AVAX, CELO XRP only. Optional destination tag — REQUIRED by most exchanges to credit an XRP deposit. Ignored for non-XRP networks.
12345
Address derivation index
Interpretation of amount. "decimal" (default) = human-readable coin amount. "base" = raw base units (integer only, used as-is). Omit for the safe default.
decimal, base Response
Base-unit gross_amount, fee_amount, recipient_amount, decimals, fee_address and fee_quote_hash. Excludes gas and conditional TRON sponsorship charges.
