Example use cases

“Before I bid on vintagecars.net at auction, can you pull its spam score and backlink data from Karma.Domains so I know if it's worth buying?”
SEO agency domain vetting workflow
“I need to check whether techblog.org has a low spam score and decent domain authority — can you look it up on Karma.Domains?”
Bulk shortlist filtering by spam risk
“I've shortlisted recipes.io as a potential domain purchase — can you check its spam score, domain authority, and referring domains on Karma.Domains before I commit?”
Technical details
Endpoint
GEThttps://api.karma.domains/v1/domains/checker/spam_score?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, per-domain spam score and core SEO health metrics (DA, backlinks, referring domains) before purchasing or using an expired domain. It is best suited for single-domain lookups where spam risk assessment is the primary goal, rather than broad discovery or full traffic analytics.
Side effects
- Missing or invalid domain parameter returns an error
- Non-existent or unrecognized domain may return all zeros for metrics
- Rate limiting or payment failure (x402) blocks the request
- Malformed domain string (e.g. missing TLD) may cause parsing errors
