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 age/registration history details, including how long the domain has existed, useful for evaluating its SEO authority and historical value before purchase or backorder.
Example use cases
Evaluating expired domain for SEO purchase
“Can you check how old backlinkhero.com is? I want to know its domain age before I bid on it at auction to see if it has enough history to be worth the SEO value.”
Comparing domain ages for a shortlist
“I have three candidate expired domains I'm considering buying — seoboost.net, trafficpro.com, and linkmaster.io. Can you check the age of each one so I can prioritize the oldest for its SEO authority?”
Auditing competitor domain history
“I want to know how old my competitor's domain digitalmarketingpros.com is — can you look up its registration age so I can understand how long they've been building domain authority?”
Technical details
Endpoint
GEThttps://api.karma.domains/v1/domains/checker/domain_age?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly verify or compare the age of a specific domain name, particularly in the context of evaluating expired domains for SEO value, authority, or purchase decisions. It is most useful when you already have a domain name in mind and need a fast, single-domain age lookup rather than a broad search across the expired domain inventory.
Side effects
- Invalid or malformed domain name returns an error response
- Domain not found in Karma.Domains database returns empty or null result
- Network timeout if the database lookup takes too long
- Missing required 'domain' query parameter returns a 400 bad request
- Non-existent TLDs or unsupported domain formats may return no data
