Pre-flight DeFi transaction cost check

“How much gas will it cost to deploy my ERC-20 smart contract on the Base network right now?”

Endpoint
POSThttps://blackbobs-ai.vercel.app/api/gas-estimate?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to estimate gas costs specifically on the Base chain before executing a transaction. It is particularly useful for cost-gating logic in agents (e.g. only proceed if gas is below a threshold) or for displaying fee previews to users in Web3 applications.
Side effects
- Invalid or missing transaction parameters resulting in estimation failure
- Network congestion causing unreliable estimates
- Stale gas price data if network conditions shift rapidly
- Malformed request body returning a 400 error
- Service unavailability on the Vercel deployment returning 5xx errors
