How this service works
Find expired domain names with high traffic and strong SEO backlinks daily. Boost your revenue by searching our database of 13,000,000+ expired domains from auctions, backorders, and dropped lists—complete with rich metrics and domain age.
Output
Returns a JSON object containing the domain name and its current registration status (e.g. 'Registered', 'Expired', 'Dropped'), drawn from Karma.Domains' database of 13M+ expired domains covering auctions, backorders, and drop lists.
Example use cases
Expired domain opportunity scouting
“Check whether 'vintagecoffee.com' is still registered or if it's expired — I'm thinking of picking it up for a new project.”
Competitor domain monitoring
“Look up the registration expiry status of 'techstartupxyz.com' on Karma.Domains — I want to know if it's still active or has lapsed.”
Bulk domain vetting pre-purchase
“Before I place a backorder, can you verify the current registration status of 'healthblog2010.net' — is it expired, registered, or already dropped?”
Technical details
Endpoint
GEThttps://api.karma.domains/v1/domains/checker/registration_expiry?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, single-domain registration and expiry status check backed by a large expired-domain database (13M+ records). It is especially useful when evaluating whether a domain is available through expiry channels (auctions, backorders, dropped lists) rather than standard registrar availability checks. Prefer this over generic WHOIS tools when SEO and traffic metrics context matters or when working within the Karma.Domains ecosystem.
Side effects
- Missing required 'domain' query parameter returns a validation error
- Invalid domain format may return an error or unexpected status
- Domain not found in the database may return an ambiguous or null status
- Rate limiting or payment failures ($1.50 USDC per call) may block the request
- Network timeouts for unresponsive upstream WHOIS or registry lookups
