Ahrefs API Alternatives: Cost and Data Trade-offs

Choose an Ahrefs API alternative by the output you need to preserve. A domain score, a 1,000-row backlink sample, a historic link profile and a competitor keyword report are four different jobs. A cheaper authority endpoint will not replace the other three, and a periodic snapshot will not answer whether a link appeared yesterday.

This comparison covers seven alternatives, including RankParse, which publishes this article. Pricing reference: 17 October 2026. Vendor prices, access terms and usage rates below are previously recorded reference values, not freshly verified current offers. Confirm current terms through the linked official pricing pages before purchasing. Prices are USD with the billing cadence shown. The workload calculations are illustrative; they do not establish equal coverage or identical returned links.

For Ahrefs subscriptions, unit mechanics and 100-domain examples, start with Ahrefs API pricing. This page focuses on choosing a provider and what a migration changes.

Start with the taskCopy Anchor Link

“Consider first” means a candidate for a sample test. It is not a ranking based on observed coverage or latency; we did not run those comparisons for this revision.

Access and billing comparisonCopy Anchor Link

Official pricing links are included so you can verify the figures before purchase. A minimum deposit, a subscription charge and consumed usage are different costs.

Do not compare index-size headlines as if they measure the same thing. Historical backlinks, current links, discovered URLs and unique referring domains are different units. For coverage, evaluate the domains and fields your product actually uses.

1. RankParse for bounded backlink research and enrichmentCopy Anchor Link

RankParse charges prepaid credits with no subscription. The base rate is $0.01/credit; purchases of 10,000 credits use $0.008 and purchases of 100,000 use $0.006. $10 for 1,000 credits is an example purchase, not a minimum-purchase claim. Credits never expire. The credit schedule documents endpoint charges and refund rules.

A backlinks call costs 2 credits with scoring off, or 3 with score=true. Either can request up to 1,000 rows. A domain-authority lookup costs 1 credit and returns RankParse's own score, not Ahrefs DR or Moz DA.

Use sort=recent when you need URL-level rows. The default importance sort can return aggregated referring-domain rows, which are useful for some research but do not constitute 1,000 individual backlink URLs. There is no offset pagination; total is the number of rows in the response, not the domain's complete link count.

Choose it for: a bounded snapshot sample, prospect enrichment or an authority signal whose definition you can adopt and validate.

Check the data age: the core graph is a periodic snapshot built from quarterly public-web releases. Check the active dataset date in the response-format documentation, rather than assuming the current quarter is deployed. Recent-sort requests and MCP tool calls read that snapshot; they do not initiate a live crawl. RankParse also lacks a market-wide competitor keyword database and Ahrefs' historical continuity. See data provenance and freshness and RankParse vs Ahrefs.

2. DataForSEO for usage-based backlink and broader API dataCopy Anchor Link

The DataForSEO pricing reference lists $0.024 per backlink task plus $0.000036 per returned row. If those rates apply without other usage charges, a full 1,000-row result consumes $0.024 + 1000 × $0.000036 = $0.06. The recorded minimum top-up is $50. Confirm any recurring backlink-product fee, product-specific funding requirement and complete access cost; a wallet deposit alone does not establish full product access.

Choose it for: a provider with backlink data and separate keyword, SERP and other API products when you want usage billing instead of a suite subscription.

Check before migrating: freshness for your target set, supported result depth, any other applicable product requirements, Basic Auth, task request bodies and nested responses. It supplies its own index and metrics, so it does not reproduce an Ahrefs report by changing the hostname. See RankParse vs DataForSEO.

3. Moz API when Moz DA is the requirementCopy Anchor Link

The Moz pricing reference lists 50 free rows/month and a paid ladder starting at $20/month for 3,000 rows. Larger listed monthly allowances include 15,000 rows for $75, 50,000 for $125, 120,000 for $250 and 500,000 for $500. Custom pricing applies above the published range.

Choose it for: a deliverable that explicitly requires Moz Domain Authority or other Moz metrics. Those names identify a particular provider's calculation.

Check before migrating: which returned objects count as rows, operation availability, rate limits and overage terms. A 500,000-row plan is not automatically proof that a specific complete-profile export is supported. See RankParse vs Moz and authority API options.

4. Majestic for Trust Flow and historic linksCopy Anchor Link

Majestic's pricing reference places full API access on the $399.99/month API plan, with monthly billing and 100 million analysis units. Lower dashboard subscriptions do not establish the same full API entitlement.

Choose it for: Trust Flow, Citation Flow, historic link research or a workflow already built around Majestic's indexes.

Check before migrating: whether to use the Fresh or Historic index, the relevant command's unit cost and the exact API entitlement. Neither its metrics nor its notion of freshness is an interchangeable Ahrefs DR feed. It is link-focused rather than a broad keyword suite. See RankParse vs Majestic.

5. SE Ranking Data API for broader SEO dataCopy Anchor Link

SE Ranking's API pricing reference describes a pay-as-you-go wallet from $50, with non-expiring purchased credits, and a separate annual plan. Its API offering covers backlinks, keyword and SERP data, with additional capabilities depending on the product.

Choose it for: evaluating several SEO data categories without assuming a backlink-only provider supplies them all.

Check before migrating: endpoint credit rates, result limits, coverage and which methods belong to your purchased product. The wallet entry amount is not an estimate for the 500-domain job below. A unit quote is still needed. See RankParse vs SE Ranking Data API.

6. Serpstat when you also want the suiteCopy Anchor Link

The Serpstat pricing reference lists API access from Team at $100/month, monthly billing.

Choose it for: a team that wants the platform and can use the associated keyword and domain-data API methods.

Check before migrating: the current method catalog, backlink access and included API allowance. A subscription entry price alone does not establish that a large backlink job fits. We have not assigned the 500-domain workload a cost based only on that headline price.

7. OpenPageRank for a single free metricCopy Anchor Link

The OpenPageRank reference describes a free plan covering 30,000 domains/month, with up to 100 domains per call. It provides an authority-style score derived from an open web graph.

Choose it for: bulk scoring where that specific signal is sufficient and you can validate its meaning for your application.

Check before migrating: score distribution and missing-domain behavior. It does not return backlinks, referring-domain profiles or anchors. It cannot run the backlink-row workload below, even if it can score every domain for free.

A consistent worksheet: 500 domains, up to 1,000 rows eachCopy Anchor Link

The existing use case is a one-off prospect list of 500 domains with up to 1,000 URL-level backlink rows per domain. That is a maximum target of 500,000 rows. Assume successful calls, no retries and enough matching data. These are conditional modeled costs using the recorded reference rates, not executed tests, current quotes or equal-coverage claims.

For Ahrefs, assume a total of five 1-unit billable fields per row, including any charged filter or sort fields. Its multi-request totals assume the chosen endpoint supports non-overlapping retrieval slices. Row caps alone do not establish such a mechanism.

For RankParse, scoring every linking domain with score=true changes consumption to 1,500 credits, a $15 base-rate value. The requested row limit does not guarantee 1,000 results per target; empty responses are still charged normally. For DataForSEO and other row-metered providers, returned-row counts change the calculation.

The 100-domain worksheet in Ahrefs API pricing uses the same assumptions: 200 ordinary RankParse credits and 500,000 modeled Ahrefs units for the backlink job. This 500-domain scenario multiplies those totals by five. A separate authority lookup adds another task and must be priced separately.

When to keep AhrefsCopy Anchor Link

Keep Ahrefs when you need its proprietary DR in an established report, recent-link discovery from its continuous crawl, historical continuity or suite data your alternative does not supply. Index updates do not guarantee a discovery deadline for each link.

If your team already pays for an eligible plan, compare the incremental unit purchase with an alternative's incremental cost. Charging the entire subscription to a small API experiment can make a migration look more attractive than it is. Conversely, if you are buying a subscription solely for an occasional script, include that new fixed cost.

For keyword-heavy workflows, compare the suites directly in Ahrefs API vs Semrush API. A lower-priced link graph is not a replacement for the entire suite.

Migration: preserve meaning as well as field namesCopy Anchor Link

Start with a small representative set: well-linked domains, niche domains, new sites and a domain where a missing result matters. Record requested fields, returned row shapes, data age and consumed usage. We have not run that evaluation for you.

An Ahrefs-style url_from field maps conceptually to RankParse's from_url, and url_to to to_url. That does not preserve the index, ranking, filters, historical data or score. Recalibrate any thresholds based on DR, and ensure downstream code can tolerate null anchors, empty results and aggregate rows where applicable.

A supported RankParse SDK request looks like this; it is a usage example, not an observed response:

import os
from rankparse import RankParseClient

with RankParseClient(api_key=os.environ["RANKPARSE_API_KEY"]) as client:
    result = client.backlinks("stripe.com", limit=1000, sort="recent")

links = result["data"]
print(result["total"])  # number of rows returned in this response

There is no offset pagination for this endpoint. If your requirement is all backlinks beyond the result ceiling, do not call the migration complete after the first sample. Review the backlinks contract and identify a provider or export route that supports the required depth.

FAQCopy Anchor Link

Which alternative is cheapest?Copy Anchor Link

For this defined 500-domain sample, RankParse has a $10 base-rate consumption value and DataForSEO $30 if the recorded task and row rates apply without other usage charges. DataForSEO product access or recurring fees must be checked separately. The outputs and freshness differ. This is not a universal cheapest-provider claim for every backlink, keyword or historical job.

Can I get backlink data without a subscription?Copy Anchor Link

RankParse uses prepaid credits, DataForSEO uses a funded balance, and SE Ranking offers a pay-as-you-go wallet as well as an annual plan. Check the relevant endpoint and purchase terms. Avoid substituting the minimum deposit for the job's consumption cost.

Can an authority score replace Ahrefs DR?Copy Anchor Link

Only if you are willing to adopt and validate a different metric. Moz DA, OpenPageRank and RankParse's score are not interchangeable DR values. If a client contract requires DR, retain an authorized source for it.

What can 100 free RankParse credits do?Copy Anchor Link

They cover 100 successful authority lookups, 50 ordinary backlink calls, or 33 scored calls with 1 credit remaining. Combining endpoints changes that allocation.

What to build nextCopy Anchor Link

Use the Ahrefs cost guide to estimate the incumbent workload, then test the chosen alternative on a representative sample. For RankParse, begin with backlinks and domain authority, review pricing, and use the 100 free credits to check output fit before funding a larger run.
