}Features
Both the total link count and the number of unique referring domains in one response — referring domains being the stronger signal, since many links from a few sites count for less than links from many distinct ones.
Separate dofollow and nofollow counts let you compute the ratio that flags an unnatural, manipulated profile versus a healthy organic mix.
Authority scores at both the domain and the specific-page level, so you can vet a whole site or just the one URL you're considering for outreach.
Trailing 30-day gained and lost link counts surface link velocity — call it on a schedule to chart growth or catch decay before it costs rankings.
The target field accepts a root domain, a subdomain, or a full URL, so the same endpoint covers both site-wide audits and single-page link checks.

console.log(data);The backlink checker API — link profiles, referring domains & authority
YepAPI's Backlinks Summary API returns any target's aggregate backlink profile in one lightweight call: total backlinks, unique referring domains, the dofollow/nofollow split, domain and page authority, and the count of links gained and lost in the last 30 days. It's a backlink checker API for fast link audits — gauge strength, track growth or decay, and benchmark competitors without pulling the full link list.
Pass a domain, subdomain, or specific URL and get clean JSON back, ready to store or chart. At $0.03 a call with no monthly minimums, it's the cheapest way to screen link prospects, monitor a profile over time, and power agency reporting. When you need the individual links or anchor texts, the dedicated backlink endpoints take over — this summary is the headline read, all under one API key.
What is a backlink checker API?
A backlink checker API returns a site's link-profile metrics as structured data instead of a dashboard — total backlinks, referring domains, dofollow ratio, and authority. That makes link auditing automatable: screen hundreds of domains, monitor profiles on a schedule, and feed the numbers into your own tools. YepAPI's summary endpoint delivers all the headline backlink metrics, plus 30-day new and lost counts, in a single $0.03 call.
Build your own link audit tool
Build a link-audit or backlink-monitoring tool on this endpoint. The summary gives you totals, referring domains, dofollow ratio, authority, and link velocity — enough to power prospect-vetting workflows, competitor benchmarks, decay alerts, and white-label client reports. Pair it with the Backlinks List API for the individual links and the Backlinks Anchors API for anchor-text distribution when a target warrants a deeper look.
Backlink checker API pricing — $0.03 per call
Backlink checker API pricing is $0.03 per summary, with no monthly minimums, seats, or contracts. Ahrefs and Majestic gate link data behind monthly or four-figure plans with row credits; Moz rate-limits its API. YepAPI is pay-as-you-go with $5 of free credit — about 165 calls — to start. Screen as many domains as you like and pay only for the calls you actually run.
Monitor backlink growth and decay
Monitor any profile by calling the summary on a schedule and storing the totals plus the 30-day new and lost counts. Chart referring-domain growth to prove a link campaign is working, or watch the lost-links figure to catch decay before it costs rankings. At $0.03 a call, daily monitoring of a portfolio of domains costs a few dollars a month.
