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 amount (in gas units) required to execute the specified transaction on Hyperliquid, allowing callers to budget fees and validate transactions before on-chain submission.
Example use cases
Pre-trade gas budget check
“I'm about to place a large order via a Hyperliquid smart contract — can you estimate the gas cost first? Sender is 0xMySender, recipient contract is 0xHLContract, calldata is 0xabcdef, value is 0x0.”
DeFi bot cost forecasting
“My trading bot needs to know the gas estimate for a Hyperliquid swap before it executes — the from address is 0xBotWallet, to is 0xSwapRouter, data is 0x38ed1739..., and value is 0x0.”
Smart contract deployment cost estimate
“How much gas will it take to call this Hyperliquid contract? From 0xDeployer, to 0xTargetContract, calldata 0x60806040..., value is 0x0.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/hyperliquid/gas/estimate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a gas estimate specifically for Hyperliquid network transactions before submission. Prefer this over generic EVM gas estimators when operating on Hyperliquid's L1 or its EVM-compatible layer, especially when paying per call is acceptable and you need fast, on-demand estimates without setting up your own RPC node.
Side effects
- Invalid or malformed address in 'to' or 'from' fields returns an error
- Malformed hex calldata in 'data' field causes a parsing error
- Network unavailability or Hyperliquid RPC downtime returns a timeout or 503
- Transaction that would revert on-chain may return an execution revert error
- Missing required fields (e.g. 'to') may return a 400 bad request
