Scanna

A 0-100 insider-risk score for ONE wallet, from that wallet's stats row alone: a single primary-key read, never a scan. Wallet age uses materialized first_seen; when absent, wallet_age_days is null and contributes NOTHING, so the score is LOWER than for a wallet whose age is known. Missing wallet is 400. A wallet with no row is 404 - and so is a stats-read FAILURE, which this route cannot distinguish. A thin-wallet score is a billable 200.

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.

Using Roundhouse, look up the x402 service Scanna 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=Scanna'
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://api.scanna.xyz/insider-score, 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.

https://roundhouseai.io/skill.md first — it is the whole procedure.
