How this service works
Pay-per-call Base onchain data, token risk verdicts and x402 payability audits over x402 (USDC on Base).
Output
Returns a JSON object with three fields: baseFeeGwei (current base fee per gas in Gwei), maxFeeGwei (recommended max fee per gas in Gwei), and maxPriorityFeeGwei (recommended miner/validator tip in Gwei). These correspond to EIP-1559 gas parameters for the Base L2 network.
Example use cases
Pre-transaction gas check
“Before I send this USDC transfer on Base, can you check what the current gas fees look like — I want to know the base fee and max fee so I'm not overpaying?”
DeFi bot cost optimization
“I'm running an arbitrage bot on Base — pull the current gas oracle data so I can figure out if the priority fee right now makes my trade profitable.”
Gas spike monitoring
“Check the Base network gas fees right now and tell me if the base fee is above 0.01 Gwei, because I'm waiting for a cheap window to batch my transactions.”

Endpoint
POSThttps://aether-x402.vercel.app/v1/base/gas?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time EIP-1559 gas fee estimates specifically for the Base L2 network and are comfortable paying micro-fees via x402 (USDC on Base). Prefer this over free gas APIs when you need reliable, pay-per-call access without API key management, or when already operating within the x402 payment ecosystem on Base.

- Base RPC node unavailable — may return 503 or timeout
- Malformed request body — returns 400 Bad Request
