SEMrush API Pricing (2025): Plans, Units, Limits & How to Access It Affordably 2026: Plans, Features & Best Deals Compared

The SEMrush API is one of the most powerful programmatic SEO data interfaces available. It provides developers, agencies, and data analysts with machine-access to SEMrush’s enormous database of keyword data, backlink information, domain analytics, and competitive intelligence. If you’re building an SEO reporting tool, integrating competitive data into a client dashboard, or automating large-scale keyword research, the SEMrush API is an industry-leading option. In this guide, we’ll cover everything you need to know about SEMrush API pricing in 2025 — including how API units work, what’s included in each plan, and how to access the SEMrush API at a reduced cost.

What Is the SEMrush API?

The SEMrush API gives programmatic access to the same data you see in SEMrush’s interface, without needing to log in manually. Through RESTful API calls, you can retrieve:

• Domain analytics — organic traffic estimates, paid traffic, number of keywords, visibility trends
• Keyword data — search volume, CPC, keyword difficulty, intent, SERP features
• Backlink data — linking domains, backlink count, authority score, anchor text
• Competitive intelligence — top competitors, traffic gap analysis, keyword gap
• Position tracking — daily rank changes for tracked keywords
• SERP data — complete SERP snapshots for any keyword and location
• Site audit data — technical issues identified during crawls

The API is available across all paid SEMrush plans, with the amount of data you can pull scaling with your subscription tier.

How Does SEMrush API Pricing Work?

SEMrush API access is measured in API units. Each API request consumes a certain number of units depending on the report type and the amount of data returned. Here’s how the unit system works:

• Each API call returns a specific number of rows
• Every row costs 1 API unit
• The number of units consumed per request scales with the data returned
• For example: requesting 100 keyword rows from the Keyword Overview report costs 100 units

API unit allocations reset monthly on your billing date. Unused units do not roll over.

SEMrush API Units by Plan (2025)

Additional API units can be purchased as add-ons if you exhaust your monthly allocation. The add-on pricing varies but typically costs around $0.01 per unit when purchased in bulk blocks.

SEMrush API Unit Costs by Report Type

Different API endpoints consume different numbers of units per call. Here are approximate costs for common reports:

At 10 units per row, the Pro plan’s 3,000 monthly units translates to approximately 300 rows of data per month before purchasing add-ons. This makes the Pro API allocation quite limited for high-volume programmatic use — most serious API consumers will need the Business plan or higher.

SEMrush API Key Features and Endpoints

Domain Analytics API

The Domain Analytics endpoint is one of the most used. It allows you to:

• Retrieve estimated organic traffic for any domain
• See all keywords a domain ranks for, with positions and traffic estimates
• Identify a domain’s top organic competitors
• Access historical domain performance data (available on Guru and Business plans)

Keyword Research API

Programmatically research keywords without manual input. Pull keyword difficulty scores, search volumes, CPC data, and trend data for hundreds of keywords in a single batch call.

Keyword Magic API

Access SEMrush’s Keyword Magic Tool via API to generate thousands of long-tail keyword suggestions from a seed term, filtered by search volume, difficulty, and intent.

Backlink Analytics API

Retrieve backlink profiles for any domain or URL including authority scores, linking domains, anchor texts, and new/lost links. Essential for automated link auditing and prospecting workflows.

Position Tracking API

Pull daily rank tracking data for all tracked keywords — perfect for building custom ranking dashboards that display SERP performance for clients without requiring direct SEMrush interface access.

Site Audit API

Trigger and retrieve site audit results programmatically. Build automated technical SEO health checks into your workflows or generate scheduled reports for clients.

Who Uses the SEMrush API?

SEO Agencies

Agencies use the SEMrush API to power white-label client dashboards — pulling live SEMrush data (keyword rankings, traffic estimates, backlink counts) into branded reporting interfaces without requiring clients to have their own SEMrush login.

SaaS Companies

Marketing SaaS platforms integrate SEMrush API data to enrich their own features — for example, content brief tools that pull SEMrush keyword data to suggest target keywords for writers.

Data Analysts

Marketing data teams use the API to build custom analytics models — combining SEMrush data with first-party analytics data in BI tools like Looker, Tableau, or BigQuery.

Enterprise SEO Teams

Large in-house SEO teams automate reporting, rank monitoring, and competitive analysis using the SEMrush API to eliminate manual data export and import workflows.

SEMrush API vs. Ahrefs API vs. Moz API

Data Breadth

SEMrush’s API offers the broadest data types — covering keyword research, competitive intelligence, backlinks, site audit, and advertising data all within one API. Ahrefs focuses primarily on backlinks and keywords. Moz specialises in authority metrics and spam scores.

Pricing

Moz’s API is generally the most affordable for smaller usage volumes. SEMrush API access is more expensive at scale. Ahrefs API is primarily enterprise-only. For most agencies and smaller data teams, SEMrush’s Business plan provides the best balance of unit volume and data breadth.

Rate Limits

SEMrush’s unit system can feel limiting at the lower plan tiers. If you need high-volume programmatic access, the Business plan’s 10,000 units/month becomes a minimum viable allocation. Ahrefs and Moz API plans can be more predictable in cost for certain use cases.

The Most Cost-Effective Way to Access SEMrush API

For agencies and developers who need SEMrush access — including its API — without the $249–$499/month Business plan price, Toolsurf’s group buy model offers the most practical solution.

Toolsurf provides access to SEMrush through its SEMrush group buy platform, dramatically reducing the per-user cost of SEMrush access. While group buy access is primarily designed for interface-level use rather than high-volume API integration, it’s ideal for agencies and analysts who need the SEMrush interface with moderate API access at an affordable price.

Toolsurf also provides access to Ahrefs, Moz Pro, and dozens of other premium SEO and marketing tools — making it one of the best group buy SEO tools platforms for building an affordable, enterprise-quality SEO toolkit.

Tips for Making the Most of Your SEMrush API Units

Cache API Responses

Don’t make redundant API calls for the same data. Implement a caching layer in your application so that data fetched once is stored locally and reused until it’s stale. For most SEMrush metrics, a 24-hour cache is appropriate.

Use Batch Requests

Where the API supports batch queries (multiple domains or keywords in a single call), always use them. Batch requests are more unit-efficient than sequential single-URL queries.

Prioritise High-Value Reports

Not all API reports deliver equal ROI per unit. Domain overview data and keyword difficulty are typically the highest-value data points. If you’re constrained on units, focus your API calls on the data that drives the most actionable decisions.

Monitor Unit Consumption

SEMrush’s API management dashboard shows your unit consumption in real-time. Set up alerts when you reach 75% of your monthly allocation so you can adjust usage before hitting the limit.
