How this service works
Real working API providing live EIP-1559 gas fee estimation (slow, standard, fast) and network congestion metrics for Base L2.
Output
Returns EIP-1559 gas fee estimates broken down into slow, standard, and fast tiers (likely including maxFeePerGas and maxPriorityFeePerGas values in gwei), along with a network congestion metric indicating current Base L2 load.
Example use cases
Pre-transaction gas check
“Before I submit this transaction on Base, can you check the current gas fees and tell me whether to use slow or fast — and how congested the network is right now?”
DeFi bot fee optimization
“My trading bot is about to swap tokens on Base — what's the current standard and fast gas fee so I can decide which priority level to use?”
Gas cost monitoring alert
“Check the Base network gas oracle and let me know if congestion is high and what the fast-tier EIP-1559 fee is at this moment.”
Technical details
Endpoint
GEThttps://robotshop.up.railway.app/api/v1/products/prod-base-gas-oracle/buy?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-tier EIP-1559 gas fee data specifically for the Base L2 network with congestion context. Prefer it over general Ethereum mainnet gas oracles when your transactions or contracts are on Base, and when you need structured slow/standard/fast tiers rather than a single estimate.
Side effects
- Network connectivity issues to Base RPC nodes may return stale or unavailable data
- Invalid or malformed client_id may be rejected
- Rate limiting or payment failures (402) if USDC payment not properly attached
- Base L2 node downtime could result in timeout or error response
