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 a gas estimate (in gas units) for the described Zora transaction — used to predict transaction cost before submission. May include estimated gas limit and possibly a fee in native token terms.
Example use cases
Pre-flight NFT mint cost check
“Before I mint this NFT on Zora, can you estimate the gas it will cost? The sender is 0x1234...abcd, the contract address is 0x5678...ef01, and the calldata is 0x40c10f19 with zero value.”
Smart contract interaction cost preview
“I want to call a Zora smart contract at 0xDEAD...BEEF from my wallet 0xABCD...1234 with data 0xa9059cbb — can you tell me how much gas that will use before I send it?”
DApp gas fee UX display
“Show me the estimated gas for a Zora transfer from 0xSender...111 to 0xRecipient...222 sending value 1000000000000000 with no extra calldata.”

Endpoint
POSThttps://synapse-api-brown.vercel.app/api/zora/gas/estimateWhen to prefer
Use this endpoint when you need a gas cost estimate specifically for the Zora blockchain network before submitting a transaction. Prefer this over generic EVM gas estimators when working with Zora NFT contracts, Zora creator tools, or any Zora L2 interaction. It's best for pre-flight checks to prevent transaction failures or budget overruns.
Side effects
- Invalid or malformed address in 'to' or 'from' fields returns a validation error
- Malformed hex calldata in 'data' field causes a parse error
- Zora RPC node unavailable returns a 5xx error
- Transaction would revert on-chain may return a gas estimation failure or error message
- Missing required fields may return a 400 bad request
- Very high gas estimates if calldata is unexpectedly large
