Semrush API Pricing: Access, Units and Alternatives

The dated Semrush Standard API reference describes an eligible paid subscription plus separately purchased API units. Confirm current access and purchase terms before budgeting. There is no reliable single “Semrush API price” to multiply by your request count. First establish which subscription unlocks the API, then price the units for the reports and rows you need. A general SEO subscription price is not proof of API entitlement.

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 plan eligibility and unit prices with Semrush's API access documentation and pricing page before purchasing. The workload calculations below are illustrative.

This guide covers direct Standard API budgeting first, then explains the different rules for Trends and MCP. For API design and feature assessment, read the Semrush API review. For the narrower backlink comparison, use RankParse vs Semrush.

Which access route are you buying?Copy Anchor Link

“Semrush API” can mean several different products. Keep the entitlement and usage balance attached to the route you actually intend to use.

The recorded Standard API access reference uses Business subscription wording. The pricing reference describes a newer lineup, with API integration on custom-priced Advanced/Enterprise offerings. A one-to-one mapping between those labels is not established.

That mismatch is a reason to ask Semrush which current SKU grants direct Standard API access. It is not a reason to attach the cheapest SEO plan's price to an API comparison. Before checkout, obtain confirmation that names the product, direct API entitlement, separate unit package and billing cadence.

Known versus quote-required budget worksheetCopy Anchor Link

A budget can be complete in units while still incomplete in dollars. Leave the dollar cell open until the unit quote is known. Also ask whether a package is shared with other integrations, so the balance you budget is actually available to this job.

Report type and API version change the meterCopy Anchor Link

The Semrush developer documentation is the source for endpoint-specific pricing and limits. Do not apply a backlink rate to a keyword report or a historical-data rate to a live report.

Set a result limit explicitly. A query that returns 100 rows and one that returns 1,000 rows do not have the same bill merely because each is one HTTP request. Check the chosen endpoint for maximum limits, filters, continuation support and error charging; row caps vary by report.

Worked backlink calculationsCopy Anchor Link

Assume 100 valid domains, successful responses, no retries and enough data for every requested row. The job asks for URL-level backlinks, not an authority score, traffic estimate or keyword report. These are conditional billing calculations using the reference rates, not measured outputs or evidence that vendors return identical links.

A bounded first sample: 100 rows per domainCopy Anchor Link

100 domains × 100 returned rows = 10,000 rows
v3: 10,000 × 40 = 400,000 API units
v4: 10,000 × 45 = 450,000 API units

This small sample is a useful integration budget before requesting larger outputs. It still consumes units from a separate package for direct Standard API access.

A larger target: up to 1,000 rows per domainCopy Anchor Link

100 domains × 1,000 returned rows = 100,000 rows
v3: 100,000 × 40 = 4,000,000 API units
v4: 100,000 × 45 = 4,500,000 API units

These totals assume the chosen endpoint and account support retrieving the target rows. If multiple requests are needed, use only documented continuation or non-overlapping query slices. We have not verified a complete-export procedure for every report version. If fewer rows are returned, recalculate the per-line charge from that output; add any other charge documented for the chosen report.

Do not multiply 4.5 million units by a price found in an undated third-party guide. The complete cash model is:

new access cost = eligible subscription + required unit-package purchase
job usage value = returned rows × applicable unit rate × quoted price per unit

Package sizes can make the purchase larger than the usage value. If you already hold an eligible subscription and enough uncommitted units, incremental cash outlay may be zero for this run, even though it consumes a paid balance.

The same requested row target on RankParseCopy Anchor Link

For RankParse backlinks, assume one limit=1000, sort=recent call per domain with scoring disabled:

The $10 purchase is an example, not a claim about the minimum checkout. Other purchase sizes and larger-volume credit rates are described in credits and pricing. With score=true, each call costs 3 credits and this job consumes 300 credits.

The requested maximum is comparable; the datasets and resulting links are not identical. RankParse uses a periodic link-graph snapshot built from quarterly public-web releases. Check the active dataset date in the response-format documentation; do not assume a current-quarter release. sort=recent returns URL-level rows within that snapshot, not live discovery. Default importance-sorted output can contain aggregated referring-domain rows. The endpoint has a 1,000-row ceiling and no offset pagination, so it is unsuitable for an unrestricted complete-profile export.

MCP entitlements are a separate budgetCopy Anchor Link

Confirm current MCP eligibility, included usage, renewal and additional-unit terms through Semrush's developer documentation. Check which tools can spend each balance and whether Trends tools require separate data access. An MCP allowance does not establish direct Standard API access on the same terms.

A client or model subscription is another potential bill. Compare tool access, data usage and model costs separately. The SEO MCP pricing guide explains the full workflow budget.

Alternatives by the data you actually needCopy Anchor Link

The cheapest provider for a backlink sample may not supply your traffic-intelligence or competitor-keyword workflow. The options below use the pricing reference above, with USD and billing cadence indicated. Check the linked official source before purchase.

Keep Semrush when its competitive keyword coverage, Trends data, historical reports or existing suite investment is the reason for the purchase. Compare alternatives when the actual requirement is a limited link or domain-data task. The Ahrefs API vs Semrush API comparison helps when the decision is between the two suites.

Before approving a budgetCopy Anchor Link

Record the current eligible subscription SKU, API product/version, reports, domains, rows and date ranges. Ask for a unit-package quote with its validity and renewal terms. Estimate retries and other consumers of the same balance. Then run a bounded sample and compare actual billed units and returned data with the worksheet before expanding.

If an example compares costs, require the same requested output size and distinguish an existing balance from a new purchase. If it compares capabilities, require the same question: a first-party Search Console report and a competitor-ranking report answer different questions even when both contain keywords.

FAQCopy Anchor Link

How much does Semrush API access cost?Copy Anchor Link

The dated Standard API reference describes an eligible paid subscription plus separately purchased API units. A complete dollar price requires a current quote. Request the eligible SKU and package quote from Semrush rather than treating a general SEO plan price as the API price.

Does Business include units automatically?Copy Anchor Link

The recorded Standard API access reference describes units as separately purchased. Confirm current direct API and MCP terms independently, including which route and balance your account has.

Is there a free Semrush API tier?Copy Anchor Link

The referenced access options do not identify a general free Standard API tier. If your plan includes MCP units, that allowance does not establish free arbitrary API access.

Can I use RankParse instead of Semrush?Copy Anchor Link

For supported backlink and domain-data tasks, evaluate it on a representative sample. RankParse does not reproduce Semrush's competitor keyword rankings, proprietary scores, traffic analytics or historical coverage.

What to build nextCopy Anchor Link

Choose one report and calculate its units before buying broad access. For a supported link-data sample, read the backlinks reference, review RankParse vs Semrush, and use the pricing page to distinguish consumed credits from a purchase. New accounts receive 100 free credits, enough for 50 ordinary backlink calls with scoring off.
