How this service works
Gas Estimate (polygon). Polygon gas estimate for a transaction (?to=, ?from=, ?data=, ?value=) with current gas price and estimated fee in the native coin; reverts reported cleanly.
Output
Returns a JSON object with: chain identifier (e.g. 'polygon'), estimated gas units as a number, current gas price in gwei, estimated fee expressed in native token (MATIC), a boolean indicating whether the simulated transaction would revert, and an error string if estimation failed. Gas and fee fields are null if estimation fails.
Example use cases
Pre-flight DeFi swap cost check
“I want to call the Uniswap router on Polygon at 0x1b02dA8Cb0d097eB8D57A175b88c7D8b47997506 with swap calldata 0xa9059cbb... — can you estimate the gas cost before I send it?”
Detect reverting transaction before broadcast
“Will this transaction revert? I'm trying to call 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174 on Polygon with calldata 0x095ea7b3 — check the gas estimate and tell me if it reverts.”
Optimize gas budget for batch automation
“I'm building an automation that sends multiple Polygon transactions per hour — can you estimate the gas for calling 0x8f3Cf7ad23Cd3CaDbD9735AFf958023239c6A063 so I can calculate my daily cost in MATIC?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/polygon/estimate-gas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a gas estimate specifically on the Polygon (MATIC) network before submitting a transaction. Use it for pre-flight checks, cost forecasting, or detecting reverts without spending gas. Prefer it over Ethereum/Base siblings when your target contract is deployed on Polygon. It is a read-only simulation — no transaction is broadcast.
Side effects
- Invalid or non-checksummed 'to' address returns error field with description
- Transaction simulation reverts — reverted: true with null gas and error message explaining revert reason
- Malformed calldata causes simulation failure
- Network congestion or RPC unavailability may return error
- Missing required 'to' query parameter results in bad request
