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) needed to execute the specified transaction on the Kaia network, allowing callers to budget fees and validate transaction feasibility before broadcasting.
Example use cases
Pre-flight DeFi swap cost check
“Before I execute this token swap on Kaia, estimate the gas cost — the sender is 0x1234abcd..., the contract is 0x5678ef01..., and the calldata is 0x38ed1739... with no ETH value attached.”
Smart contract deployment gas planning
“I'm about to deploy a new smart contract on Kaia — can you estimate how much gas it will take? From address is 0xMyWallet..., the deployment bytecode is 0x6080604052..., and value is zero.”
Safe transfer validation before sending KAIA
“I want to send 10 KAIA from 0xSenderWallet... to 0xRecipient..., can you estimate the gas fee so I know if I have enough to cover the transaction?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/kaia/gas/estimateWhen to prefer
Use this endpoint when you need to estimate gas specifically on the Kaia blockchain network before sending a transaction. Ideal for DApp developers, DeFi bots, and wallet agents that need to pre-validate transaction costs on Kaia without executing a real transaction. Prefer over generic RPC calls when you want a pay-per-call, infrastructure-free approach without running your own node.
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 — estimator returns revert error or zero gas
- Network congestion or RPC node unavailability causes timeout
- Missing required fields returns 400-level validation error
- Payment not included or insufficient — returns 402 Payment Required
