Why Use a Dedicated USDT API?

USDT requires specialized handling for network fees (gas) and smart contract interactions. Our API handles all underlying blockchain infrastructure, returning simple JSON objects.

Unified Network Endpoints

You do not need separate codebases for Ethereum and TRON. Our unified API allows your users to select their preferred network while you process all logic through a single interface.

Instant Balance Tracking

Query our API to get real-time balances of your merchant wallets across all supported networks, allowing for automated treasury management and reporting.

Requesting a specific Network

Easily specify TRC20 when creating the invoice.

curl -X POST https://api.smartcloudpay.com/v1/invoice \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "amount": 100,
    "currency": "USD",
    "target_crypto": "USDT",
    "network": "TRC20"
  }'
