Open Page Rank Pricing: API Costs and Tiers (2026)

Pricing overview

Open Page Rank provides access to its PageRank, Domain Rating, and Traffic APIs through a tiered subscription model, designed to accommodate varying usage levels from individual developers to larger SEO platforms. The pricing structure is primarily based on the number of API requests allowed per month. A free tier is available for initial exploration and low-volume usage, while paid plans scale up in request capacity and corresponding monthly fees. This model is common among API providers, allowing users to select a plan that aligns with their operational scale and budget constraints, as observed in other API platforms like Cloudflare's API operations or Stripe's API documentation.

The service aims to offer a cost-effective solution for obtaining SEO metrics, particularly for backlink analysis, domain authority checking, and competitive research. The official Open Page Rank pricing page details the specific inclusions and limits for each subscription level.

Plans and tiers

Open Page Rank organizes its paid offerings into several subscription tiers, each providing a specific number of API requests per month. All paid plans include access to the core APIs: PageRank, Domain Rating, and Traffic data. The primary differentiator between tiers is the volume of requests.

Each plan is designed to scale with user demand, offering a progressive increase in request capacity. Users can upgrade or downgrade their plans as their needs evolve. Overages beyond the monthly request limit typically result in additional charges or require an upgrade to a higher tier.

Free tier and limits

Open Page Rank provides a free tier that allows users to test the API and integrate it into their applications without an initial financial commitment. This free plan includes 1,000 API requests per month.

• Request Limit: 1,000 requests per month.
• Included APIs: Access to PageRank, Domain Rating, and Traffic APIs.
• Purpose: Suitable for evaluation, small personal projects, and understanding API functionality.

The free tier serves as an entry point, enabling developers to build and test integrations before committing to a paid subscription. Once the 1,000-request limit is reached within a month, further requests will be denied until the next billing cycle begins or the user upgrades to a paid plan. Details on how to access and utilize the API are available in the Open Page Rank API documentation.

Real-world cost examples

Understanding the practical application of Open Page Rank's pricing model can help developers and businesses estimate their monthly expenses. The cost is directly tied to the number of API requests made. A single request typically retrieves data for one domain or URL.

1. Scenario A: Individual Developer Testing
   An individual developer is building a personal SEO tool and needs to check the PageRank for approximately 50 unique domains per day. Over a month (30 days), this would amount to 50 domains/day * 30 days/month = 1,500 requests/month. The Free Tier (1,000 requests/month) would be exceeded. The developer would need to subscribe to the Basic Plan at $29/month, which provides 25,000 requests, comfortably covering their usage.
2. Scenario B: Small SEO Agency
   A small SEO agency manages 20 client websites and performs weekly backlink analysis, checking 100 competitor domains for each client. This involves 20 clients * 100 domains/client * 4 weeks/month = 8,000 requests/month. Additionally, the agency runs ad-hoc reports, adding another 2,000 requests. Total monthly requests: 10,000. The Basic Plan ($29/month for 25,000 requests) would be sufficient.
3. Scenario C: Mid-sized Content Platform
   A content platform with 5,000 articles regularly monitors the PageRank and Domain Rating of internal and external links. If they check 1,000 links daily, this totals 1,000 links/day * 30 days/month = 30,000 requests/month. This usage exceeds the Basic Plan. The platform would opt for the Standard Plan at $49/month, which provides 50,000 requests, accommodating their needs with headroom.
4. Scenario D: Large SEO Software Provider
   A large SEO software provider integrates Open Page Rank data into their platform, serving thousands of users. They anticipate needing to process 10,000 requests per day for various domain and traffic metrics. This equates to 10,000 requests/day * 30 days/month = 300,000 requests/month. This volume would require the Business Plan at $199/month, offering 500,000 requests, providing ample capacity for their operations. For even higher volumes, the Enterprise plan with custom pricing would be considered.

These examples illustrate how usage patterns directly influence the most suitable pricing tier, emphasizing the importance of estimating monthly request volumes when selecting a plan.

How the pricing compares

Open Page Rank operates within a competitive market for SEO data APIs. Key alternatives often include established players such as Ahrefs, Moz, and SEMrush, which also offer API access to their extensive datasets. While direct feature-for-feature and price-per-request comparisons can be complex due to varying data points, granularity, and API design, some general observations can be made.

• Ahrefs API: Known for extensive backlink data and its proprietary Domain Rating (DR) and URL Rating (UR) metrics. Ahrefs' API access is typically available to subscribers of their higher-tier plans, which can start at significantly higher price points than Open Page Rank's entry-level plans. For instance, Ahrefs' pricing for advanced features often begins in the hundreds of dollars per month, with API access potentially adding to that cost or being bundled into premium subscriptions. Its comprehensive dataset may justify a higher price for users requiring very deep and extensive backlink profiles. More details are available on the Ahrefs API documentation.
• Moz API: Offers access to its Domain Authority (DA) and Page Authority (PA) metrics, along with link data. Moz's API pricing is usually structured around tiers based on query volume, similar to Open Page Rank, but often with higher starting points. Moz's data is highly regarded in the SEO community, and its API is suitable for those specifically targeting DA/PA metrics and Moz's proprietary link index. Pricing details can be found on the Moz API page.
• SEMrush API: Provides a broad range of SEO data, including keyword research, competitor analysis, traffic analytics, and backlink data. SEMrush typically offers API access as part of its business or enterprise-level subscriptions, which are generally more expensive than Open Page Rank's mid-tier plans. SEMrush's strength lies in its all-in-one SEO suite, making its API valuable for users needing diverse data points from a single source. Pricing information is available on the SEMrush API overview.

Open Page Rank generally positions itself as a more focused and potentially more cost-effective solution for users primarily interested in PageRank, Domain Rating, and Traffic metrics, especially for those who do not require the full suite of tools offered by larger platforms. Its free tier and lower starting prices for paid plans can make it an attractive option for individual developers, startups, or projects with specific, narrower data requirements, or those looking to augment existing SEO toolkits without significant overhead.
