How this service works
Live network gas prices (slow / average / fast, in gwei) for any chain — the pre-transaction read every trading, sniping, and settlement agent makes before sending a tx to size the fee. Across Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis. Free upstream (Blockscout); one paid call instead of running your own RPC.
Output
A JSON object with numeric gas price values for fast, average, and slow transaction speeds in gwei, plus the chain name and unit label. Example: {fast: 0.71, average: 0.55, slow: 0.42, unit: 'gwei', chain: 'ethereum'}.
Example use cases
Example prompt
“What are the current gas prices on Base — give me fast, average, and slow gwei estimates so I can decide when to submit my transaction.”
Technical details
Endpoint
GEThttps://x402-agent-store.rileycraig14.workers.dev/chain/gasWhen to prefer
Use this endpoint when an AI agent needs real-time EVM gas price data across multiple chains (Base, Ethereum, Optimism, Arbitrum, Polygon, Gnosis) without managing API keys or subscriptions. Ideal for autonomous agents that pay per-call in USDC via x402 and need lightweight, no-signup gas oracle access before executing on-chain transactions.
Side effects
- Unsupported chain name returns error or default fallback to ethereum
- Network congestion or upstream RPC unavailability may cause stale or missing data
- Missing 'chain' query param defaults to ethereum — agent must be aware of this default
- Payment failure via x402 (insufficient USDC balance) blocks the call entirely
