Use it before you send to an address, or to screen sign-ups and leads for typos, disposable domains and role addresses. Checks syntax, MX records (with the A-record fallback), null MX, a list of about 120,000 disposable domains, role addresses (info@, support@…) and free providers, without sending anything. No SMTP probing, so it can't confirm the mailbox exists. Never charged for errors: we settle the payment only after a successful answer.

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.
