How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns a gas estimate (in gas units) for the described MegaETH transaction, allowing the caller to assess transaction feasibility and fee costs before broadcasting.
Example use cases
Pre-flight gas check for ETH transfer
“Before I send 1 ETH to 0xRecipient123 on MegaETH from my wallet 0xMyWallet456, can you estimate how much gas that transaction will need?”
Gas cost for smart contract call
“I want to call a MegaETH smart contract at 0xContract789 with this calldata: 0xa9059cbb000... — can you estimate the gas cost for me so I know if my budget is sufficient?”
Cost comparison before batch deployment
“I'm about to deploy several transactions on MegaETH and need to budget. Estimate the gas for a transaction from 0xDeployer111 to 0xTarget222 with value 0 and data 0x60806040...”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/megaeth/gas/estimateWhen to prefer
Use this endpoint when you specifically need gas estimates for the MegaETH network (not mainnet Ethereum or other EVM chains). It is ideal for agents that need to preflight transactions, budget gas fees, or validate transaction feasibility before committing on MegaETH. Pay-per-call x402 pricing at $0.01 USDC makes it cost-effective for occasional lookups.
Side effects
- Invalid or malformed Ethereum address in 'to' or 'from' fields returns an error
- Invalid hex data in 'data' field causes parsing failure
- Transaction would revert on-chain may return an error or unreliable estimate
- Network unavailability on MegaETH RPC results in timeout or 503
- Missing required fields may return validation error
