How this service works
Scans recent block gas details to estimate the minimum, average, and maximum base fee.
Output
A JSON object containing the average, maximum, and minimum base fee in gwei for the queried period, a 'supported' boolean indicating whether the network is covered, and a confidence level string (e.g. 'high').
Example use cases
Example prompt
“What were the average, minimum, and maximum gas base fees on Ethereum over the last 24 hours? I want the gwei breakdown with a confidence rating.”
Technical details
Endpoint
POSThttps://statepulse-api.hahavoid0.workers.dev/blockchain/gas-historyWhen to prefer
Use this endpoint when an agent needs historical gas fee statistics (avg/min/max base fee) for a blockchain network and wants a simple, structured summary rather than raw block-by-block data. Good for cost estimation, timing optimization, or trend analysis. Requires no API key; pay-per-call at $0.01 USDC via x402 on Base.
Side effects
- Unsupported blockchain network returns supported:false
- Invalid or out-of-range time/block parameters return an error
- Network connectivity issues to the Cloudflare Worker may cause timeouts
- Payment failure via x402/USDC on Base blocks the request
