How this service works
Base mainnet data primitives paid per call with USDC over x402 v2.
Output
A JSON object containing the network identifier (e.g. 'eip155:8453' for Base mainnet) and the current gas price expressed in wei as a string (e.g. '1000000'). The caller pays $0.005 USDC per request via x402 v2.
Example use cases
Pre-transaction gas estimation
“Before I submit this transaction on Base, what's the current gas price so I can estimate the total fee?”
DeFi bot gas threshold check
“Check the current gas price on Base mainnet and tell me if it's below 2000000 wei — I only want to execute my trade if gas is cheap enough.”
Real-time gas monitoring dashboard
“What is the live gas price on Base right now? I'm building a dashboard and need the latest wei value for chain eip155:8453.”

Endpoint
GEThttps://x402-market-seven.vercel.app/api/base/gas-price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call lookup of the current Base mainnet gas price without committing to a subscription, or when building an agent that dynamically fetches on-chain gas costs using x402 micropayments. Prefer it over self-hosted RPC calls when you want a simple REST interface with no node infrastructure to manage.
Side effects
- Payment not included or invalid x402 USDC payment header — returns 402 Payment Required
- Network or RPC connectivity issue fetching live Base chain data — may return 503 or error JSON
- Malformed request — returns 400 Bad Request
- Gas price data momentarily unavailable due to Base RPC lag — stale or error response
