ValidationBimi ValidationBimiEmail BrandingDmarc Check

Checks one or more domains to see whether they are set up to show a brand logo next to emails in Gmail, Apple Mail, and Yahoo. It looks up the BIMI settings the domain has published, checks the logo file follows the required format, checks any logo certificate is valid and unexpired, and confirms the domain has strict enough email protection turned on. Returns a clear pass or fail per domain, plus a plain list of what is broken when something fails.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
