How this service works
Cheap EVM read utilities for AI agents on Base and Ethereum mainnet: gas and fees, blocks, balances, ERC-20 metadata, contract inspection, transaction status, ENS/Basename resolution, bulk balances. No API key: pay USDC on Base per call via x402.
Output
A JSON object containing: the chain queried, current ETH/USD price, base fee in gwei, priority fee estimates (low/standard/fast in gwei), and per-operation cost estimates (gas units, cost in ETH, cost in USD) for common transaction types like ETH transfers.
Example use cases
Pre-transaction gas check
“Before I send this ETH transfer, check the current gas fees on Base and tell me what it'll cost me in USD — and which priority level I should use for a standard confirmation speed.”
Cross-chain fee comparison
“What are the gas fees on Ethereum mainnet right now? Give me the base fee and how much a simple ETH transfer would cost in both ETH and USD.”
Gas price monitoring alert
“Check the current gas price on Base for me — I want to know if the base fee is below 0.01 gwei so I can decide whether to submit my transaction now or wait.”
Technical details
Endpoint
GEThttps://chainread.imac2014ville.workers.dev/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when your agent needs real-time EVM gas pricing data for Base or Ethereum mainnet without provisioning an API key — ideal for cost estimation before submitting transactions, UX display of current fees, or dynamic gas strategy decisions. Prefer this over general blockchain RPC calls when you want a clean, pre-computed fee estimate in USD with tiered priority levels for $0.001 USDC per call.
Side effects
- Invalid chain parameter value (not 'base' or 'ethereum') returns an error
- RPC node outage may cause stale or unavailable fee data
- Payment failure (insufficient USDC or x402 protocol error) blocks the request
- Network congestion may cause response latency spikes
