How this service works
Returns the current gas price for a specified blockchain network.
Output
Returns live gas snapshot including base fee in gwei, p50 and p90 priority fees from eth_feeHistory, USD cost estimates for native transfer, ERC-20 transfer, and swap transaction types, plus the current ETH/USD price from CoinGecko used in cost calculations.
Example use cases
Monitor network congestion before batch payments
“Check the current gas situation on Base for me — what's the p90 priority fee right now, and roughly how much would it cost in USD to send a batch of ERC-20 transfers? Should I wait for congestion to drop or go ahead?”
Compare L2 costs for optimal route
“I need to do a token swap, but I'm not sure which network to use. Can you pull the current swap costs in USD on Arbitrum and Optimism so I can pick the cheapest one?”
Budget allocation for transaction execution
“What's the base fee and p50 priority fee on Ethereum right now in gwei? Also tell me what a native ETH transfer would cost in USD so I know how much gas to allocate for my transaction.”
Technical details
Endpoint
GEThttps://meryol-agenticmarket-x402.hf.space/gas/now/:chain?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs real-time gas cost data across Ethereum mainnet or major L2s (Base, Arbitrum, Optimism) before submitting a transaction, sizing a gas budget, or deciding whether to skip/defer a tx due to congestion. Prefer over raw RPC calls because it normalizes gwei values, computes USD costs per tx type, and folds in ETH/USD pricing in a single call.
Side effects
- Unsupported chain value returns 422/400 validation error
- RPC node timeout or unavailability returns 503 or error response
- CoinGecko ETH/USD price feed unavailable may cause USD cost fields to be null or stale
- Payment not made or invalid x402 header returns 402 Payment Required
- Network congestion on the queried chain may cause eth_feeHistory call to timeout
