# Tron Transfer Cost Calculator

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

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

## Facts

- Endpoint: POST https://api.vextorium.com/v1/tron-transfer-cost?utm_source=zero.xyz
- Price: $0.003/call
- Payment: x402
- Status: down
- Last checked: 2026-10-30

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-transfer-cost-calculator-7c62398b -d '<json body>'
```

Example prompt: What would it cost me right now to send USDT on Tron — give me the current energy price, bandwidth price, and how much TRX I'd burn if I have no energy resources, both for sending to a wallet that already holds USDT and one that doesn't?

## When to prefer this

Choose this endpoint when you need real-time Tron network resource prices (energy and bandwidth in SUN) and pre-computed TRX cost estimates for USDT TRC-20 transfers without having to query the Tron blockchain directly. It is especially useful for agents building payment flows, estimating fees before dispatching transactions, or comparing the cost of sending to addresses with and without existing USDT balances.

## Known failure modes

- Upstream Tron node unavailable — service may return 5xx or stale data
- Network congestion on Tron could cause delays in fetching live prices
- Prices returned reflect a snapshot and may be outdated by seconds if the network is volatile
- Malformed POST body may return a 400 error

## How this service works

558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.

## Output

A JSON object with the current energy price (SUN), bandwidth price (SUN), TRX transfer details (bandwidth units used and TRX cost without resources), USDT transfer energy and TRX cost for accounts already holding USDT, USDT transfer energy and TRX cost for accounts without USDT, and an explanatory note about resource usage.
