# Tron USDT & TRX Transfer Cost Calculator

> Tron USDT & TRX Transfer Cost Calculator is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-30).

Returns current energy and bandwidth prices on Tron, plus the typical energy consumption and TRX cost of sending USDT (TRC-20) and TRX to accounts with and without existing USDT balances.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tron-usdt-trx-transfer-cost-calculator-55cc3e7f -d '<json body>'
```

Example prompt: What are the current Tron network fees for sending USDT TRC-20 — give me the energy price, bandwidth price, and how much TRX I'd burn if I have no resources staked, both to a wallet that already holds USDT and to a fresh one?

## When to prefer this

Choose this endpoint when you need real-time Tron network fee data specifically for USDT TRC-20 and TRX transfers, including the distinction between transfers to wallets with and without existing USDT — especially useful for fee estimation before executing a send, or for deciding whether to rent/stake energy. Prefer this over general blockchain fee APIs if you specifically operate on the Tron network with USDT.

## Known failure modes

- Tron RPC node temporarily unavailable — may return 5xx error
- Energy/bandwidth price oracle stale if Tron network is congested
- No input body parameters required but malformed POST body may cause 400
- Prices reflect a snapshot in time and may shift rapidly during high-activity periods

## How this service works

What it costs right now to send USDT (TRC-20) and TRX on Tron: energy and bandwidth prices, typical energy of a USDT transfer to an address with and without USDT, and the TRX burned if you have no resources.

## Output

A JSON object with: current energy price (SUN per unit), current bandwidth price (SUN per unit), bandwidth units consumed by a TRX transfer and its TRX cost without resources, energy units consumed by a USDT transfer to an account that already holds USDT and its TRX cost without resources, energy units consumed by a USDT transfer to an account without USDT and its TRX cost without resources, plus explanatory notes about free daily bandwidth and staking benefits.
