How this service works

Track Base network fee trends over time — avg gas per block, cheapest hours, L1 vs L2 comparison. Useful for agents timing their transactions.

Output

Returns Base network gas fee trend data including average gas per block over time, identified cheapest hours for transactions, and a comparison of L1 versus L2 fee costs to help agents choose optimal transaction timing.

Example use cases

Example prompt

“What are the gas fee trends on Base right now — show me the average gas per block, the cheapest hours to transact, and how L1 compares to L2 fees so I can time my next transaction well.”

Technical details

Endpoint

POSThttps://httpay.xyz/api/fee-tracker

When to prefer

Use this endpoint when an AI agent needs to optimize transaction timing on the Base L2 network by analyzing historical and recent gas fee patterns, particularly when cost-sensitive transactions should be scheduled during low-fee windows. Prefer this over a real-time gas price snapshot when trend analysis and cheapest-hour identification are needed.

Side effects

Network data unavailable — upstream Base RPC node unreachable
Payment not processed — 402 response if USDC payment fails
Rate limit exceeded — too many requests in short period
Malformed request body — missing required parameters returns 400
Stale data — fee trends may lag real-time conditions by a few blocks
