Example prompt: Can you check what anchor texts are used in the backlinks pointing to vintagewatches.com on Karma.Domains — I want to see its SEO anchor profile before deciding whether to buy it.

## When to prefer this

Use this endpoint when you need to inspect the specific anchor texts used in backlinks pointing to an expired domain, particularly as part of due diligence before purchasing or back-ordering a domain. It is more targeted than a general backlink count check and is best used when assessing keyword relevance, anchor diversity, or spam risk of a domain's link profile.

## Known failure modes

- Missing required 'domain' query parameter returns a validation error
- Domain not found in the database returns an empty anchors array
- Invalid domain format may return an error or empty result
- Rate limiting or payment failure (x402) may block the request
- Network timeout for domains with very large backlink datasets

## 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 with the queried domain name and an array of anchor text entries found in its backlink profile, drawn from Karma.Domains' database of 13M+ expired domains. The anchors array may be empty if no anchor data is available for the domain.
