How this service works
High-speed API suite for AI processing, web scraping, and smart data utilities across 57+ blockchain networks. Pay-per-call via x402.
Output
Returns an estimated gas amount (in gas units) for the specified transaction on the Ink blockchain network, allowing agents or users to predict fees before broadcasting the transaction.
Example use cases
Pre-flight fee check for token transfer
“Before I send 100 USDC on Ink from my wallet 0xABCDE to 0x12345, can you estimate the gas cost so I know if it's worth it at current prices?”
Smart contract call cost estimation
“I want to call a smart contract on the Ink network — the calldata is 0xa9059cbb000...and it's going to 0xContractAddress from 0xMyWallet. Estimate the gas before I send it.”
Batch transaction budget planning
“I'm planning to execute 50 transactions on Ink today — can you estimate the gas for a typical transfer with no data from 0xSender to 0xReceiver with a value of 0.01 ETH so I can figure out my total budget?”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/ink/gas/estimateWhen to prefer
Use this endpoint when you need a quick, pay-per-call gas estimate specifically for the Ink blockchain network without running your own RPC node. Prefer this over generic ETH gas estimators when targeting Ink-specific transactions, or when you need a lightweight, stateless estimation call without managing infrastructure.
Side effects
- Invalid or malformed address in 'to' or 'from' fields returns an error
- Unsupported calldata format may cause estimation failure
- Network connectivity issues with the Ink RPC may result in timeout or 5xx error
- Insufficient or malformed 'value' field may cause estimation errors
- Payment failure via x402 returns 402 Payment Required before the estimate is served
