How this service works

Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.

Output

A JSON object containing: current ETH/USD price, chain ID (8453), network name ('base'), suggested standard gas settings (maxFeePerGas and maxPriorityFeePerGas in Gwei), base fee in Gwei, current block number and timestamp, block utilization percentage, gas price in Gwei, and estimated costs (in ETH and USD) for both a standard ETH transfer (21,000 gas) and an ERC-20 token transfer (65,000 gas).

Example use cases

Pre-transaction gas check on Base

“Before I send this ERC-20 token transfer on Base, can you tell me the current gas price in Gwei and roughly how much it'll cost in USD?”

DeFi bot fee optimization

“I need the latest suggested maxFeePerGas and maxPriorityFeePerGas on the Base network so my trading bot can submit a transaction at the right fee level without overpaying.”

Real-time ETH price and network health

“What's ETH trading at in USD right now, and how congested is the Base network — give me the current block utilization and base fee.”

Technical details

Endpoint

GEThttps://quickbuild.quynguyenbac.workers.dev/api/base/gas?utm_source=zero.xyz

When to prefer

Use this endpoint when you specifically need gas data for the Base network (chain ID 8453) and want both fee suggestions and estimated USD costs for common transaction types in a single call. Prefer this over generic gas APIs when your workflow targets Base L2 and you need ERC-20 transfer cost estimates alongside ETH/USD pricing.

Side effects

Network unavailable: RPC node for Base may be temporarily unreachable, returning a 5xx error
Stale data: block timestamp may lag if the underlying RPC is behind
Rate limiting: exceeding call frequency may result in 429 errors
Payment failure: missing or invalid x402 USDC payment header returns 402
Invalid endpoint path: calling wrong route returns 404
