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) required to execute the described transaction on the Hyperliquid network, based on simulation without on-chain submission.
Example use cases
Preflight fee check for DEX swap
“Before I submit this swap on Hyperliquid, estimate the gas cost — sender is 0xAAA111..., recipient contract is 0xBBB222..., calldata is 0xa9059cbb... and value is 0.”
Smart contract deployment cost estimate
“I'm about to deploy a contract on Hyperliquid from address 0xCCC333..., with this bytecode as data and no ETH value — can you estimate the gas it will use?”
Budget planning for high-volume bot
“My trading bot on Hyperliquid sends batches of transactions from 0xDDD444... to 0xEEE555... with this calldata pattern — give me a gas estimate so I can budget my fee reserves.”
Technical details
Endpoint
POSThttps://synapse-api-brown.vercel.app/api/hyperliquid/gas/estimate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to estimate transaction gas costs on the Hyperliquid network specifically before committing to a transaction. Prefer this over generic Ethereum gas estimators when targeting Hyperliquid's L1/L2 environment, as gas parameters may differ from mainnet Ethereum.
Side effects
- Invalid or malformed Ethereum address for 'to' or 'from' fields returns a 400 error
- Malformed or non-hex 'data' field may cause estimation failure
- Hyperliquid RPC node unavailable returns 5xx error
- Transaction simulation reverts (e.g. insufficient balance or bad calldata) may return an error or revert reason
- Missing required fields may cause incomplete estimation or error response
