Arbitrum Gas Estimate
Arbitrum Gas Estimate is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown.
Estimates the gas units and ETH cost of a transaction on Arbitrum One using eth_estimateGas, returning gas, gwei, and ETH cost at the current gas price.

How this service works
Estimate the gas a transaction would use on Arbitrum One (eth_estimateGas) and what it would cost at the current gas price, in gas units, gwei and ETH. Give to, plus value in ETH and calldata for a contract call, and the sender when the call depends on it. Use before sending a transaction or to price a batch; for the gas price alone use arb_gas. A transaction that would revert is 422 with the reason, uncharged.
Output
Returns a JSON object with: the recipient address (to), estimated gas units (gas), total transaction cost in ETH (cost), sender address (from), current block number (block), chain name (chain), chain ID (chainId), ETH value being sent (value), native symbol (symbol), and current gas price in gwei (gasPriceGwei). If the transaction would revert, returns HTTP 422 with the revert reason and no charge.
Example use cases
Pre-flight check before token transfer
“I'm about to send 100 USDC to 0xRecipient...1234 on Arbitrum — can you estimate the gas cost in ETH first so I know what fee to expect? My wallet is 0xMySender...5678 and the calldata is 0xa9059cbb...”
Batch transaction cost pricing
“I need to send 50 identical contract calls on Arbitrum tomorrow and want to know the total gas cost. Can you estimate the gas for one call to 0xContract...9abc with calldata 0x12345678... from 0xMySender...def0 so I can multiply it out?”
Revert detection before on-chain execution
“Will this Arbitrum transaction revert? Call to contract 0xDeFiPool...abcd from 0xMyWallet...1111 with calldata 0x38ed1739... and 0 ETH — I want to know the gas estimate or the revert reason before I actually submit it.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/arb/estimate-gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to know the exact gas cost of a specific transaction or contract call on Arbitrum One before submitting it, especially when the cost depends on calldata or sender address. Prefer this over arb_gas (which gives only the current gas price) when you need the full simulation including gas units and total ETH cost. Ideal for pre-flight checks, batch pricing, and revert detection.
Side effects
- 422 if the transaction would revert on-chain — includes the revert reason string, not charged
- Invalid or malformed address returns an error
- Missing required 'to' parameter returns a 400-level error
- Network or RPC unavailability may cause timeouts
- Calldata that is not valid hex may be rejected
