Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-gas-estimate-arbitrum-7a970077
```

Example prompt: Before I send this transaction to 0xAbCd1234... on Arbitrum with calldata 0xdeadbeef, can you estimate how much gas it will use and what the fee will be in ETH?

## When to prefer this

Use this endpoint when you need on-chain gas estimation specifically for the Arbitrum L2 network. Prefer it over Ethereum mainnet or Polygon gas estimators when targeting Arbitrum contracts. It is ideal for pre-flight checks before submitting transactions, profitability calculations in DeFi bots, and validating whether a transaction would revert without spending real gas.

## Known failure modes

- Invalid or malformed 'to' address returns an error field in the response
- Transaction simulation reverts — reverted field is true and gas may be null
- Network congestion or RPC issues may cause estimation failures
- Missing required 'to' query parameter results in an error
- Calldata that causes out-of-gas scenarios may return null gas values

## How this service works

Gas Estimate (arbitrum) — On-Chain Data

## Output

Returns a JSON object with the chain name, estimated gas units, gas price in gwei, estimated fee in native token, whether the transaction would revert, and an error message if applicable. Gas and fee fields may be null if estimation fails.
