How this service works
Live facts and unblockers for agents: real-time EVM gas prices and a web fetch relay. x402-payable, first call free.
Output
A JSON object containing the network name ('base'), a UTC timestamp, the current base fee in Gwei, the current gas price in Gwei, the current priority fee in Gwei, and the latest block number. All values reflect real-time on-chain state at the moment of the request.
Example use cases
Pre-transaction gas check
“Before I submit this transaction on Base, can you check what the current gas price and base fee are so I can decide if now is a good time?”
Gas price monitoring alert
“Keep an eye on the Base network gas prices and let me know when the base fee drops below 0.005 Gwei — poll it every few minutes.”
DeFi bot cost estimation
“Pull the latest gas price data from Base right now — I need the base fee, priority fee, and block number to estimate the cost of my automated arbitrage transaction.”
Technical details
Endpoint
GEThttps://x402desk.vercel.app/x402/gas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time EVM gas price data specifically for the Base network and want a simple, low-cost ($0.001 USDC) micropayment-gated REST call rather than running your own RPC node or subscribing to a heavyweight gas oracle. Ideal for agents that need occasional gas checks without managing blockchain infrastructure.
Side effects
- RPC node unavailable — may return 5xx or stale data
- Network congestion causing delayed block data
- x402 payment failure if wallet/facilitator is misconfigured
- Rate limiting if called excessively without payment
- Unsupported network requested — endpoint may only cover Base
