How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns an estimated gas/energy and bandwidth cost for the specified Tron transaction, allowing the caller to assess resource requirements and potential TRX fees before submitting the transaction on-chain.
Example use cases
TRC-20 token transfer cost check
“Before I send 500 USDT on Tron from my wallet TLxxxxMyWallet to TRxxxxFriend, can you estimate how much energy and bandwidth this TRC-20 transfer will consume?”
Smart contract interaction fee preview
“I want to call a Tron smart contract at TGxxxxContract with this calldata: 0xa9059cbb0000... — estimate how much gas I'll need so I know if my wallet has enough resources.”
DeFi swap cost estimation
“Estimate the energy cost of this Tron DEX swap transaction: from TLxxxxMyAddress, to TGxxxxDexRouter, with calldata 0x38ed1739... and value 0 — I need to know the fee before confirming the swap.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/tron/gas/estimateWhen to prefer
Use this endpoint when you need a quick, pay-per-call gas estimate for Tron network transactions without managing your own Tron node or RPC infrastructure. Ideal for agents handling TRX or TRC-20 transactions that need pre-flight fee checks before committing a transaction. Prefer this over general-purpose blockchain APIs when specifically targeting the Tron network.
Side effects
- Invalid Tron address format for 'to' or 'from' fields returns a 400 error
- Malformed or oversized calldata may cause simulation failure
- Network connectivity issues to Tron RPC nodes may return 503 or timeout
- Insufficient input parameters (missing required fields) returns validation error
- Tron node rate limiting may cause intermittent failures
