}Features
Each result returns the exact sourceUrl and sourceDomain of the linking page, so you see precisely where a domain earns its links rather than an aggregate count.
Every backlink includes its anchorText and an isDofollow boolean, letting you audit anchor distribution and separate equity-passing links from nofollow ones in code.
Each row carries a domainAuthority value, so you can sort a backlink profile by link quality and surface the strongest referrers first.
The limit field (default 100) sets how many backlinks return; billing adds $0.006 per 100 rows on top of the $0.04 call, keeping large pulls inexpensive.
Common domain lookups return quickly from cache, so backlink checks slot into real-time tools and audit dashboards without long waits.

console.log(data);The backlink checker API for developers — full referring profiles with anchor text & authority
The Backlink Checker API returns the links pointing to any domain, each with its source URL, anchor text, dofollow status, and source-domain authority. Pass a domain and a limit, and get a structured backlink profile you can audit, score, or visualize.
It is the entry point for link research at YepAPI. For deeper drill-downs — anchor distribution, referring domains, or competitor link gaps — the sibling Backlinks endpoints share the same key and response conventions.
What is a backlink checker API?
A backlink checker API returns the inbound links pointing to a website as data instead of a dashboard report. For a domain like github.com you get each linking page's sourceUrl, sourceDomain, anchorText, whether it is dofollow, the referrer's domainAuthority, and a firstSeen date. That turns link research into something you can automate — score profiles, flag toxic links, or build outreach lists programmatically. YepAPI serves this from /v1/seo/domain/backlinks: post a bare domain (no protocol) and a limit, and receive a JSON array drawn from production-grade link data infrastructure.
Build your own backlink checker tool
Build an SEO dashboard that shows a domain's top backlinks ranked by domainAuthority, or an outreach tool that filters for dofollow links from high-authority sources. The firstSeen timestamp lets you track when links appeared, powering link-velocity charts. Because the data is plain JSON, you can pipe it into a spreadsheet export, a toxic-link scanner, or a competitor-comparison view. Pair it with the Referring Domains API to deduplicate by site and the Anchors API to analyze anchor spread.
Backlink checker API pricing — $0.04 + $0.006 per 100 rows
Each call is $0.04 plus a thin $0.006 per 100 rows returned, so a default 100-backlink pull costs about $0.046 and even a thousand-row profile stays near a dime. Compare that to the $999/mo plans behind Ahrefs' API access or Majestic's $399/mo tier — you get the same link fields, billed per request, with no annual contract.
Reverse-engineer competitor backlinks
Point the endpoint at a competitor's domain to see exactly which pages link to them and with what anchors. Sort the response by domainAuthority to find their most valuable referrers, then build a targeted outreach list of sites already inclined to link in your niche. Running this across several competitors reveals the link sources common to all of them — the highest-probability targets for your own campaign.
