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.

Provider

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Accepts

GET api.roundhouseai.io/v0/endpoints

Using Roundhouse, look up the x402 service lab.paidapis.net and tell me whether it is
worth paying: what a call costs, whether the endpoint answered when last probed, and what
its payment record actually shows.

curl -s 'https://api.roundhouseai.io/v0/endpoints?q=lab.paidapis.net'
curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>'

Then call it: read the price from the live 402 at https://lab.paidapis.net/api/gas-metrics, never from
a cached figure, and pay with an x402 client.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402,
or use an organization key from https://roundhouseai.io/dashboard/team.
