Penny Engine — Base Network Gas & Block Info
x402
Penny Engine — Base Network Gas & Block Info is a paid API for AI agents from penny-paid-batch-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-19).
Returns current Base network (EIP-155:8453) block number, gas price in Wei and Gwei, and nominal ETH transfer fee via a paid x402 call.

How this service works
Machine-to-machine result validation via x402. One structured call, deterministic PASS or FAIL and SHA-256 fingerprint, $0.001 USDC on Base.
Output
Returns a JSON object with the EIP-155:8453 network identifier, a timestamp of when the check was performed, the current block number, gas price in Wei, gas price in Gwei (decimal string), and the nominal ETH transfer fee in ETH. All values are deterministic snapshots of live Base chain state at call time.
Example use cases
Pre-transaction gas check on Base
“Before I submit this token transfer on Base, can you check the current gas price and tell me how much a basic ETH transfer would cost in ETH right now?”
Real-time Base block height monitoring
“What block is the Base network on right now, and what's the current gas price in Gwei? I'm trying to time a contract interaction.”
Automated fee threshold alert
“Check the current Base network gas price for me — I want to know if it's under 0.02 Gwei so I can trigger my batch transaction.”
Technical details
Endpoint
GEThttps://penny-paid-batch-production.up.railway.app/api/base-network?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need real-time gas and block data from the Base L2 network (EIP-155:8453) with micropayment-gated access via x402, and you want a structured deterministic response with both Wei and Gwei representations alongside the nominal ETH transfer cost. Prefer it over generic Ethereum mainnet gas oracles when your workflow targets Base specifically.
Side effects
- Network RPC unavailability may return an error or stale data
- x402 payment failure returns 402 with payment instructions rather than data
- Malformed or missing query parameters may return a 400 error
- Railway app cold-start may introduce latency or timeout on first call
