We sell link data by the call to people who report on it, not only to people who live in SEO tools.

Who this is for
Our reader owns a dashboard. Maybe you are a product manager asked about competitors' authority, or a growth analyst who needs one steady tile, or a founder who wants a single number for the monthly update.
That reader rarely needs a keyword suite. Just a score. A count, and a cost they can defend when a colleague pushes back in a review. So the whole product is built around those: a free lookup, a JSON API, and prepaid credit.
Our pages are written to answer the questions that come up in those jobs. Examples: how to explain a rating to a board with our runbook, or what a link source costs per metric in the Moz pricing breakdown.
What we run
01
Our own crawler and index
181,132,097 domains, 2,774,625,913 domain-to-domain links and about 798.5 billion backlinks, refreshed roughly once a month.
02
A public DR formula
Domain Rating is round(100 log(ref_domains + 1) / log(2 10^7)). It is our metric, not Ahrefs DR or Moz DA.
03
Per-call pricing
One credit costs $0.0001. A new account starts with $100 free credit, no card.
04
Plain access
Sign in with a Google account. Top-ups are USDT on TRC-20 from the account page.
What we are not
We are not a replacement for Ahrefs or Semrush if you need keyword research, rank tracking or a daily-fresh crawl. We do link data, at a low price, once a month.
How we write
Every guide here starts from a job a reader has to finish. Simple. We pick a format to fit it. A comparison becomes a table, a procedure becomes a runbook, and a judgement call becomes a decision tree.
We label hypothetical numbers as examples and we do not publish customer stories, because we have none to show. When we quote another vendor, we quote only what is public, such as Ahrefs selling API units inside subscriptions from $129/month for 200,000 units.
If you spot a claim that has gone stale, tell us from your account page. Link data moves fast, and vendors change prices without warning.
What a typical month looks like
A reader lands on a guide, checks one domain in the free box, and decides whether the number is useful. Many stop there, and that is fine. The lookup costs us nothing to serve and needs no key.
Others sign in, take the $100 starting credit and script a pull. A list of a few hundred domains costs one credit per call. After that the cron job runs quietly, and the only visit to the site is a top-up months later, in USDT, when the balance runs low.
We keep the product narrow on purpose. Backlinks, referring domains, anchors, top pages and a Domain Rating cover most reporting needs. The decision tree for common domain questions shows where that stops being enough.
How to reach us
We do not publish a general mailbox. Everything goes through the account page at /account.php, where you sign in with Google and write to us from inside your account. That keeps requests tied to a real account and a real key.
Questions about a number are welcome. Include the domain, the date you pulled it and the action you called, and we will check it against our index.
