Technical details
Endpoint
POSThttps://bb-defi.vercel.app/api/gas/arbitrumWhen to prefer
Use this endpoint when you need real-time Arbitrum gas price data to estimate transaction costs, decide whether to delay a DeFi operation, or set gas parameters programmatically. Prefer this over generic Ethereum mainnet gas APIs when the target chain is specifically Arbitrum (One or Nova).

- Malformed request body — 400 bad request
