TrxAPI

TrxAPI is a REST API for developers who send USDT on the TRON network. A TRC-20 transfer burns TRX unless the sending address holds energy and bandwidth. TrxAPI lets your backend rent both resources for an address right before a payout, so the transfer uses rented energy instead of burned TRX. A typical USDT TRC-20 transfer needs about 65,000 energy. A transfer to an address that holds no USDT yet needs about 131,000. The API returns an estimate for the exact transfer, so you can see the requirement before you rent anything. Your service then requests the resources, waits for delivery and sends the transaction as usual. What the API covers: energy and bandwidth rental for any TRON address, resource estimates, subscriptions for addresses that send on a schedule, address activation, and AML checks on addresses. Requests use a Bearer token and an SHA256 X-Signature header, calculated from the request body and your secret. The documentation includes working examples in cURL, Node.js, Python and PHP. You can get an API key without KYC. TrxAPI never holds user funds and needs only a public address, never a private key or seed phrase. Integration takes an afternoon for most backends: add one call before the payout, one call to check delivery, and keep your existing signing code.
