How this service works
Returns Ethereum EIP-1559 base-fee-per-gas statistics (all-time, daily and rolling averages, min/max with block numbers, and the burn barrier) from ultrasound.money. Feeds autonomous gas-timing agents and agent-to-agent execution planners tracking ETH issuance/burn dynamics and picking low-base-fee windows. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object containing a timestamp, the niche identifier, and a result object with Ethereum EIP-1559 base-fee-per-gas statistics including all-time average, daily average, rolling averages, minimum and maximum fees with associated block numbers, and the burn barrier — sourced from ultrasound.money.
Example use cases
Timing DeFi transactions for low gas
“What does the Ethereum base fee look like right now compared to the historical average? I want to know if this is a good window to execute my on-chain transactions or if I should wait for fees to drop.”
Monitoring ETH issuance and burn dynamics
“Give me a breakdown of the current ETH burn stats and base fee trends — I'm tracking issuance versus burn dynamics and need the latest numbers including the burn barrier from ultrasound.money.”
Autonomous gas-timing agent decision making
“Check the Ethereum base fee statistics including the rolling and daily averages and tell me whether the current base fee is above or below the historical average so my agent can decide whether to proceed with the batch of transactions now or defer.”
Technical details
Endpoint
POSThttps://ethereum-basefee-burn-stats.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need structured, multi-window Ethereum base fee statistics (all-time, daily, rolling averages plus min/max with block context) in a single call, especially for gas-timing agents or execution planners that need to compare current fees against historical benchmarks. Prefer it over raw RPC node calls when you want pre-aggregated burn and fee stats without building your own data pipeline against ultrasound.money.
Side effects
- Payment failure if x402 USDC payment is not properly submitted
- Upstream ultrasound.money API unavailability causing stale or missing data
- Malformed request payload resulting in an error response
- Network timeout if the upstream data source is slow to respond
- Invalid or missing API keys causing authentication failure
