Ahrefs API review
Best backlink data
Ahrefs runs one of the largest independent web crawlers in existence, and the API is how you get at what it finds without opening the interface. Version 3 exposes Site Explorer and Keywords Explorer data as JSON, billed per row of data returned rather than per request.
The pricing is the story. A standalone API subscription starts at $500 a month, which is a hard floor rather than a starting point, and it buys 500,000 rows. Every Ahrefs plan from Lite upward also carries a smaller monthly unit allowance with a per-request row cap, which is enough to test with but not to build on.
Who Ahrefs API is for
Teams that already pay for Ahrefs and need its link data inside their own reporting. If backlink depth is the thing your work turns on, this is the reference dataset and the cost is the price of admission. If you need SERPs or keyword volume more than links, you will get the same job done for a fraction of the money elsewhere.
Strengths and limits
What it does well
- Backlink coverage and freshness that practitioners consistently rate as the best available.
- Row-based billing with published overage rates, which makes cost forecasting straightforward once you know your query shape.
- Clean, well-documented v3 endpoints that developers describe as more consistent than the main alternative.
- Every paid plan carries some API allowance, so you can prototype before committing to the $500 tier.
Where it falls short
- The $500 monthly minimum for a real API subscription prices out solo operators and small agencies entirely.
- The terms prohibit reselling or repackaging the data in a third-party product, and accounts have been suspended for it. Read them before building anything commercial.
- Long-term users report that related data is sometimes split across endpoints, so a single question can cost two calls instead of one.
Ahrefs API pricing
Three standalone tiers: API Standard at $500 a month for 500,000 rows, API Plus at $2,000 for 5,000,000 rows, and API Premium at $10,000 for 30,000,000 rows. Overage runs $1.00 per 1,000 rows on Standard, $0.40 on Plus and $0.35 on Premium.
Separately, every Ahrefs subscription from Lite upward includes a monthly API unit allowance: 100,000 units on Lite with a 100-row cap per request, 400,000 on Standard, 1,000,000 on Advanced and 2,000,000 on Enterprise with no row cap. Those allowances are sized for testing and light internal use, not for powering a product.
Rate limits and quotas
- Every billable request costs a minimum of 50 units.
- Base plans cap rows per request: 100 on Lite, 250 on Standard, 500 on Advanced, uncapped on Enterprise.
- Unit cost scales with field expense, from 1 unit for cheap fields up to 10 for traffic estimates.
Verdict
The best link data here, sold at a price that assumes you already made the decision. If backlinks are central to your work and the budget exists, nothing else is a straight swap. If they are one input among several, DataForSEO or SE Ranking will cover the same ground for a fraction of the spend, and you can keep an Ahrefs seat for the deep dives.
Ahrefs API FAQ
How much does the Ahrefs API cost?
A standalone API subscription starts at $500 a month for 500,000 rows. API Plus is $2,000 for 5 million rows and API Premium is $10,000 for 30 million. Overage is $1.00 per 1,000 rows on Standard, falling to $0.35 on Premium.Is there a cheaper way to access Ahrefs data?
Not legitimately. Every Ahrefs plan includes a small monthly unit allowance you can use for testing, and the MCP server exposes the same data for conversational use, but there is no supported route to production volumes below the $500 tier.Can I resell Ahrefs API data in my own tool?
No. The terms prohibit reselling or repackaging the data in a third-party product, and Ahrefs has suspended accounts for it. Buying API access licenses you to use the data, not to redistribute it. If you are building a commercial product, use a provider whose terms permit it.How is the Ahrefs API billed?
Per row of data returned, not per request. Every billable request costs at least 50 units, and beyond that the cost is rows multiplied by the expense of the fields you asked for, from 1 unit for cheap fields to 10 for traffic estimates. Requesting only the columns you need is the single biggest lever on your bill.Ahrefs API or DataForSEO?
Ahrefs for backlink depth and freshness, DataForSEO for everything else on a per-request budget. The two are not really competing: one is a premium subscription to a proprietary crawl, the other is metered access to a broad data catalogue. Teams with the budget often run both.
