How this service works
Current gas price on Arbitrum One (eth_gasPrice): gas price, base fee and suggested priority fee in gwei, plus what a plain ETH transfer (21,000 gas) costs right now. Takes no input. Use before sending a transaction or to decide whether to wait; for the fee a past transaction actually paid use arb_receipt.
Output
A JSON object containing the current Arbitrum One block number, chain name and ID (42161), ETH symbol, base fee in Gwei, gas price in Gwei, priority fee in Gwei, and the cost of a standard ETH transfer in ETH. Example: {block: 123456789, chain: 'Arbitrum One', symbol: 'ETH', chainId: 42161, baseFeeGwei: '0.012', gasPriceGwei: '0.015', transferCost: '0.000000315', priorityFeeGwei: '0.001'}.
Example use cases
Pre-transaction gas check on Arbitrum

DeFi bot cost optimization

Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/arb/gas?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, pay-per-call gas snapshot for Arbitrum One without setting up API keys or accounts. Ideal for agents that only occasionally need Arbitrum gas data and want to avoid subscription overhead. Prefer over general blockchain RPC calls when you want a clean, pre-parsed JSON response with Gwei and ETH transfer cost already computed.
Side effects
- RPC node unavailability for Arbitrum may return 5xx or stale data
- Unexpected network spikes may cause transient timeouts
- Payment failure (x402) means the call is never charged but returns no data
