How this service works
Estimate the gas a Base transaction will consume via eth_estimateGas before signing it (?to=&from=&data=&value=): gas units, current gas price and estimated fee in ETH, or willFail with the revert reason when it would fail.
Output
Returns a JSON object with willFail (boolean), and when successful: gasEstimate (integer gas units), current gas price (in wei), and estimated total fee in ETH. When the transaction would revert, willFail is true and a revert reason string is included.
Example use cases
Pre-flight check for ERC-20 transfer
“I'm about to send a USDC transfer on Base — can you estimate the gas and total ETH fee before I sign? From address is 0xSenderAddr, to is the USDC contract 0xA0b86991c..., with calldata 0xa9059cbb... and value 0.”
Detect revert before DeFi contract call
“I want to call a DeFi swap contract on Base but I'm worried it might revert — can you simulate the transaction with from 0xMyWallet, to 0xSwapRouter, data 0x38ed1739..., and value 50000000000000000 wei, and tell me if it will fail and why?”
Cost estimate for NFT mint
“What will it cost in ETH to mint an NFT on Base? Simulate the transaction from 0xMinter to the NFT contract at 0xNFTContract with mint calldata 0x1249c58b and value 10000000000000000 wei.”
Technical details
Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/base/estimate-gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to simulate a Base (Coinbase L2) transaction before signing to avoid wasted gas on failed transactions, preview ETH fees, or diagnose revert reasons. Prefer this over Ethereum mainnet estimators when the target chain is Base specifically. Ideal for wallets, DeFi agents, and NFT minting flows that need a dry-run before committing.
Side effects
- Missing required 'to' address returns a 400 error
- Invalid address format (non-hex or wrong length) causes a validation error
- Calldata exceeding 12 KB limit is rejected
- RPC node unavailability may cause transient 5xx errors
- Transactions that revert return willFail:true with a revert reason rather than a hard error
- Stale gas price if Base network conditions change rapidly between estimate and submission
