Majestic API review
Best link quality metrics
Majestic has been indexing links longer than anyone else here, and its metrics reflect a different philosophy from Domain Authority. Citation Flow measures link quantity, Trust Flow measures link quality by distance from a trusted seed set, and Topical Trust Flow breaks that quality down by subject.
That last metric is the reason practitioners still pay for it. Knowing a domain has Trust Flow 40 is useful. Knowing that trust is concentrated in Health rather than Gambling is what tells you whether a link is worth having.
Who Majestic API is for
Link builders and agencies that qualify prospects at volume, and anyone whose work turns on the topical relevance of a link rather than a single blended score. It is a specialist tool bought for a specific judgment.
Strengths and limits
What it does well
- Topical Trust Flow has no real equivalent elsewhere. Quality broken down by subject is a genuinely different signal from a single authority number.
- The Historic index goes back further than any competitor, which matters for domain history and expired-domain work.
- Trust Flow is conceptually closer to how link-based ranking actually works than a blended authority score.
- Analysis Units are shared across all endpoints, so one balance covers whatever mix of calls you make.
Where it falls short
- API access is $399.99 a month, a steep jump from the $99.99 Pro plan.
- Links only. No keyword data, no SERPs, no rank tracking.
- The interface and developer experience feel dated next to newer providers.
Majestic API pricing
Three plans. Lite at $49.99 a month includes 5 million Analysis Units and limited Site Explorer. Pro at $99.99 adds the Historic index, full Site Explorer, Clique Hunter and 20 million units. The API plan at $399.99 a month is the tier with real API quota and 100 million units.
Analysis Units are consumed by both interface exports and API calls from one shared balance, so heavy manual use eats into your programmatic allowance.
Verdict
A specialist buy, and a good one if link quality assessment is core to your work. Topical Trust Flow justifies the price for serious link builders and nothing else replaces it. If you need a general backlink dataset rather than this specific judgment, Ahrefs is deeper and DataForSEO is far cheaper.
Majestic API FAQ
How much does the Majestic API cost?
The API plan is $399.99 a month with 100 million Analysis Units. Lite at $49.99 and Pro at $99.99 include units but only limited API access, so real programmatic use means the top tier.What is Topical Trust Flow?
Trust Flow broken down by subject category, showing not just how trusted a domain's links are but what topics that trust sits in. It is Majestic's most distinctive metric and has no close equivalent elsewhere.Trust Flow or Domain Authority?
Trust Flow measures link quality by distance from a trusted seed set, while Domain Authority is a blended ranking prediction. Trust Flow is closer to how link-based ranking actually works, but Domain Authority is what more people recognise.What are Analysis Units?
Majestic's credit system, consumed by both interface exports and API calls from one shared balance. Heavy manual use in Site Explorer reduces what is left for programmatic queries.Is Majestic still worth using?
For link quality assessment, yes. Topical Trust Flow and the depth of the Historic index remain genuinely differentiated. For general backlink research most teams are better served by Ahrefs or DataForSEO.
