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 a gas estimate (in gas units) for the described transaction on the X Layer network, enabling the caller to anticipate transaction costs before broadcasting. May include a gas limit figure and optionally a fee estimate in native currency.
Example use cases
Pre-flight gas check for token transfer
“I want to send some tokens on X Layer — can you estimate the gas cost first? The sender is 0xABC123, recipient is 0xDEF456, and the transfer data is 0xa9059cbb...”
Smart contract deployment cost estimation
“Before I deploy my smart contract on X Layer, estimate the gas it'll take — here's the bytecode as the data field, and my deployer wallet is 0xMYDEPLOYER.”
DeFi transaction fee check before swap
“I'm about to do a swap on an X Layer DEX — can you estimate the gas for this calldata 0xswapData... being sent to contract 0xDEXContract from my wallet 0xMYWALLET with value 0?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/xlayer/gas/estimate?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when you need gas estimates for transactions on the X Layer (OKX EVM-compatible Layer 2) network. Prefer it over generic gas estimators when targeting XLayer-specific contracts or infrastructure, and when you need a pay-per-call model without subscription overhead via x402 micropayment.
Side effects
- Invalid or malformed address in 'to' or 'from' fields — returns 400 error
- Transaction would revert on-chain — estimation may fail or return a revert error
- Network congestion or RPC node unavailability — may return 503 or timeout
- Missing required fields — returns validation error
- X Layer network downtime — endpoint unavailable
