Moz Links API review
Best for Domain Authority
Moz invented Domain Authority, and that is still the main reason to use this API. DA and PA are the metrics clients, prospects and link sellers all recognise, which makes them useful as a shared vocabulary even where a technically better metric exists.
The Links API returns those scores plus linking domains, anchor text and spam score, billed by rows of data per month. Pricing is unusually legible for this category: a plain ladder from a free 50 rows a month up to enterprise volumes, with no unit multipliers to model.
Who Moz Links API is for
Anyone who needs an authority score in a product, a prospecting sheet or a client report. It is the standard pick for link-building tools and outreach qualification, where DA is what the other side of the conversation understands.
Strengths and limits
What it does well
- Domain Authority is the most widely recognised third-party authority metric, which makes it valuable for client-facing work regardless of its technical merits.
- The clearest pricing here. Flat row volumes with no multipliers, so forecasting is arithmetic rather than modelling.
- A real free tier at 50 rows a month, enough to test an integration end to end.
- Spam Score is genuinely useful for filtering link prospects at scale.
Where it falls short
- Index size and freshness trail Ahrefs and Semrush, so it is weaker as a research tool than as a scoring one.
- Narrow scope: links and authority only. No SERP data, no keyword volumes, no rank tracking.
- The free tier is rate limited to one request per ten seconds, which makes it useful for testing but not for anything batched.
Moz Links API pricing
A simple ladder. Free covers 50 rows a month at one request per ten seconds. Paid starts at $20 a month for 3,000 rows and $75 for 15,000, then $125 for 50,000, $250 for 120,000 and $500 for 500,000. Advanced is $2,000 a month for 4 million rows and Enterprise $10,000 for 40 million.
Because billing is purely row-volume with no field multipliers, the estimate you do on a napkin is the bill you get. That is rarer in this category than it should be.
Verdict
Buy it for Domain Authority, not for research. If your product or process needs an authority score that other people recognise, this is the canonical source and the pricing is the most predictable here. For actual link analysis, Ahrefs has the deeper index and DataForSEO the better economics.
