How this service works
Derived metrics: Ethereum gas price sampled continuously in the background and turned into rolling average, min/max, volatility, and trend direction over a window (?windowMinutes=, default 10) — none of which exist in the raw upstream feed's single instantaneous value.
Output
Returns a JSON object with current gas price, average, min, max, standard deviation, trend direction (up/down/flat/insufficient-data), number of samples observed, and the requested window size in minutes. All numeric fields may be null if insufficient data exists.
Example use cases
Real-time gas cost monitoring for DApp
“Check gas prices on Base right now and tell me if they're trending up or down over the past 10 minutes — I want to know if it's a cheap time to trigger a transaction.”
Volatility alert before batch submission
“Before I send a batch of on-chain transactions, can you pull gas metrics for the last 30 minutes on Base and tell me the standard deviation and whether prices have been stable?”
Historical gas window comparison
“What were the average and max gas prices on Base over the last 5 minutes? I want to see if fees spiked recently.”
Technical details
Endpoint
GEThttps://lab.paidapis.net/api/gas-metricsWhen to prefer
Use this endpoint when you need statistical gas price intelligence on Base mainnet — not just a single current reading — including trend direction, volatility (stdDev), and min/max over a configurable recent window. Prefer this over generic gas APIs when you specifically need Base mainnet data with trend analysis and are willing to pay micro-fees via x402 USDC.
Side effects
- Insufficient data returns null for all numeric fields and trend set to 'insufficient-data' when the window has too few samples
- Invalid windowMinutes value (e.g. negative or non-numeric) may result in a 400 error
- Payment failure or missing x402 payment header returns HTTP 402
- Service unavailability returns 5xx errors
