How this service works
Lightning-fast access to blockchain data, smart contract insights, and Web3 infrastructure across 57+ networks. Pay-per-call via x402.
Output
Returns a gas estimate (in gas units) for the described Celo transaction, allowing callers to anticipate fees before broadcasting the transaction on-chain.
Example use cases
Pre-flight smart contract call check
“I'm about to call a smart contract on Celo — sender 0xAbC...111, contract address 0xDeF...222, calldata 0xa9059cbb000...0064. Can you estimate the gas before I actually send it?”
CELO token transfer cost preview
“How much gas would a plain CELO transfer use? From 0x111...aaa to 0x222...bbb with a value of 1000000000000000000 wei and no calldata.”
DApp transaction cost budgeting
“My DApp needs to know the gas cost for this batch calldata on Celo before showing users a fee estimate — from 0xApp...wallet, to 0xContract...addr, data 0x1234abcd. What's the gas estimate?”
Technical details
Endpoint
POSThttps://phantom-api-omega.vercel.app/api/celo/gas/estimateWhen to prefer
Use this endpoint when you need a gas estimate specifically on the Celo network before submitting a transaction, especially when cost predictability matters or when building user-facing fee previews in a Celo DApp. Prefer this over generic Ethereum gas estimators when your target chain is Celo.
Side effects
- Invalid or malformed address in 'to' or 'from' fields returns an error
- Reverted simulation (e.g. contract call would fail) may return an error or revert message
- Missing required fields may result in a 400 bad request
- Network unavailability or RPC node issues may cause 5xx errors
- Incorrect calldata encoding may yield inaccurate estimates
