OpenFrequently asked questions
What does the domain report include?
Registration (registrar with IANA id and abuse contact, registration, expiry, update and last-transfer dates), every EPP status code explained, transfer, delete and update locks, DNSSEC, nameservers and DNS provider, A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records, the website's status, redirects, host and title, parked or for-sale detection, the HTTPS certificate, email provider with SPF, DMARC and DKIM, typical prices for the extension, an estimated value, history, transfer readiness and a list of issues ranked by severity.
Where does the data come from?
Registration data comes live from the registry's RDAP server, the modern replacement for WHOIS. For extensions without RDAP, the report asks the registry's WHOIS server instead and shows the raw record. DNS comes from Cloudflare's public resolver, and the website, certificate and email checks talk to the domain directly.
What history do you show?
Lemon Domains keeps a snapshot of the public registry record each time a domain is checked, so the report shows when it was first seen and every change since: new registrar, renewed expiry, nameserver moves and status changes. It also shows the first and latest Internet Archive captures of the website.
Is it free?
Yes, with no account. You can run 10 reports an hour. With a free account, the same report is available through the REST API and the MCP server, with 200 reports a day.
Can my AI agent use it?
Yes. Connect the Lemon Domains MCP server to Claude, Cursor or any MCP client and ask about any domain. The domain_report tool returns the whole report as JSON, and the REST API serves it at GET /api/v1/report.
Know every domain you own this well.
Lemon Domains tracks expiry, renewals and locks across all your registrars, and reminds you before anything lapses.
