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 (gas limit) for the described transaction on the Superseed network, helping callers set appropriate gas limits and anticipate transaction fees before broadcasting.
Example use cases
Pre-flight DeFi transaction check
“Before I submit this swap transaction on Superseed, estimate the gas — from 0xSenderAddress, to 0xDexContractAddress, with calldata 0xswapCalldata and 0 ETH value.”
Smart contract deployment cost estimate
“How much gas would it take to deploy my contract on Superseed? The deployer is 0xMyWallet, the recipient is the zero address, and the bytecode is 0x6080604052...”
Wallet gas budget planning
“I want to know the gas cost for sending 0.5 ETH from 0xMyAddress to 0xFriendAddress on Superseed so I can budget correctly before sending.”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/superseed/gas/estimate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need gas estimation specifically on the Superseed network and want a pay-per-call model without managing your own RPC infrastructure or API keys. Prefer it over generic RPC providers when Superseed-specific support and Web3 infrastructure reliability are priorities.
Side effects
- Invalid or malformed address in 'to' or 'from' fields returns an error
- Malformed calldata in 'data' field causes estimation failure
- Transaction would revert on-chain — gas estimation may fail or return an error indicating revert
- Network unavailability or RPC node downtime returns a 5xx error
- Missing required fields may return a validation error
