6 tools do this job

Backlink API: the backlink profile of a domain from Moz, DataForSEO, Serpstat, SE Ranking, Majestic or Semrush, per call

Give your agent a domain and get its backlink profile back as one row: total backlinks, referring domains, follow and nofollow split, the tool's authority score and, from some tools, the spam and anchor breakdowns. 6 tools answer through 鹦鹉AI, from 0.56 credits/result, each at its own rate, and none of them behind a monthly plan. Ahrefs is not among them. Every index is that tool's own crawl, so the counts differ by design, and this page does not pick one.

Billed per call, for what you use. No card required.

What is the best way to ask 鹦鹉AI?

1 · Set your agent up, once

in your agent's chat
set up 鹦鹉AI — https://parrot.amorist.cn/llms.txt

2 · Then ask for the job

the prompt
Using 鹦鹉AI, get the backlink summary for our domain and our three main competitors from the cheapest verified tool, show me the price first, then put referring domains, follow share and the authority score in one table and tell me where the gap is widest.

Why this prompt works

Give bare domains

Most tools want the domain without scheme or www, and a page URL where you mean a page. Say which, or the agent guesses.

One call per domain

Each tool prices the summary per target, and the dearest per-call tool is ten times the cheapest. Four domains is four calls.

Name the score you mean

Moz DA, Majestic Trust Flow, Semrush Authority Score: each belongs to its tool and compares only to itself. Ask for one and stick to it.

Ask for the price first

鹦鹉AI returns the rate before the call, so the agent can say what a thousand expired domains will spend before it starts.

Why 鹦鹉AI

Why go through 鹦鹉AI

No subscription, no seats

Charged per call. No card, no minimum; top up the prepaid balance.

Switch by changing a word

Another tool is a different word in the prompt, not a new integration.

From the field

What people actually struggle with

Backlink threads are among the most seeded in SEO: of the ~163 Reddit and X posts read in August 2026, one promotional ring ran to eleven posts across five subreddits with the same template, and link sellers filled most of the rest. These five are people paying for the data themselves.

Whose data do you trust for link building?

“Just started testing APIs for backlinks of the two.. Which ones data do you prefer when it comes to linkbuilding?”

r/SEO

What this page can do about it:No one can answer that for your niche. The cheap experiment: pull the same domain from Serpstat, Moz and DataForSEO for a few credits and see which index has the links you know exist.

A hundred domains a day makes the seat price absurd

“DA checks are way too expensive at volume”

r/Domains, 7 points

What this page can do about it:At volume the per-call rate is the whole story, and the cheaper summaries here carry their own tool's score. An agent looping a list of expired domains is the fit; the price of the loop is the rate times the list.

If DR is gameable, which score is not?

“If Ahrefs DR should be ignored, then which “domain rating” you should care about?”

X

What this page can do about it:None of them is more than its tool's model, and this page will not crown one. What it can do is have the agent pull four tools' scores for the same domain, with the referring-domain counts beside them, so it shows its working.

The detail

What actually differs

Per-call is the point.

The forum's problem is not the data, it is the pricing model: plans built for enterprises and seats that cost hundreds a month for one column. Here every summary is a call at its own rate, metered from a prepaid balance. 700 credits of prepaid balance is a few hundred Serpstat summaries.

Two tools are the odd ones.

Majestic's backlink and URL metrics calls are the same command, so ask for one and read both sets of columns rather than paying twice. Semrush publishes no per-call price. Neither has been called live through 鹦鹉AI yet; the other four have.

The columns are not the same shape.

Moz's call is its URL metrics with distributions on, which adds histograms by domain authority, spam score and root domains; SE Ranking's summary is ten times the price of its metrics call and adds the full breakdown, so use metrics when you only need totals; DataForSEO returns the counts, rank and spam score with breakdown arrays you can cap. Read the docs linked on each tool before the agent loops.

Background

What is a backlink API?

A backlink API returns what a link index knows about a domain or a page as data: how many pages link to it, from how many distinct domains, how many of those links pass authority, and a score the tool computes from all of it. The summary endpoint on this page is the one-row version, the profile rather than the list of links; the list is a different job. Each tool runs its own crawler and its own index, so DataForSEO, Moz, Serpstat, SE Ranking, Majestic and Semrush will each give a different referring-domain count for the same domain, and none of them is the count. Ahrefs, the index most of the forum pays for, is not in the catalog.

Questions

Before you start

Is there an Ahrefs API here?

No. Ahrefs is not in the catalog, and this page does not resell or proxy it. The six indexes here are the alternatives, each priced per call at its own rate, and the honest note is that their counts and scores are theirs, not Ahrefs'.

Why do the backlink counts differ between tools?

Because each tool crawls the web itself and keeps its own index. A link one crawler found last week is one another has not reached. There is no correct count; pick one index and compare domains within it, or pull two and treat the overlap as the confident set.

Is Domain Authority in the response?

Moz's DA comes from Moz, and only from Moz; Majestic returns Trust Flow and Citation Flow, Semrush its Authority Score, DataForSEO and SE Ranking their own rank. Each score is comparable only to itself, and no tool's number should be read as another's.

Which tool should my agent use?

The one whose columns match the question and whose rate fits the volume. 鹦鹉AI does not route or fail over for you.
