Moz API review

Moz API is a hosted SEO data API: an application connects to Moz to retrieve data for its own tools, dashboards or integrations. It sits between your application and Moz’s SEO data, rather than running as a library or self-hosted server inside your stack. Moz presents it as access to link, keyword and site data built on its index.

The API can supply metrics including Domain Authority, Page Authority and Spam Score for link analysis. Keyword features include volume, difficulty, Organic CTR, Priority, search intent and related keyword suggestions. Other listed capabilities include Brand Authority and ranking keywords for pages in Google’s top 50 results. These data points can support research workflows, competitive analysis and SEO reporting inside a product. The homepage says Moz API starts at $20; its free plan is useful for a small integration check, but its 50 monthly rows make it a narrow option for ongoing or bulk workloads.

The integration surface is Moz API and its data endpoints, with the Moz API dashboard and documentation available from the product area. The homepage describes building custom SEO tools, dashboards and integrations, but does not name an API protocol, SDK, programming language, CLI, webhook or plugin. Confirm SDK support and the exact request and response formats in Moz’s documentation before choosing a language or estimating integration work.

Moz lists keyword metrics, search intent, related keywords, Brand Authority, ranking keywords and link metrics as API capabilities. The homepage also points developers to documentation and describes it as intuitive, but does not provide language-specific setup details in its feature copy. The pricing page lists MCP access as beta enabled on paid plans from Starter Medium onward and on Enterprise; check the documentation for its scope and setup. Plan engineering time for endpoint discovery, authentication, response handling and any required data normalization.

Moz lists a free plan at $0 per month with 50 rows per month and one request every 10 seconds. Starter Medium costs $20 monthly for 3,000 rows, with no overages available. Starter Large is $75 for 15,000 rows and charges $5 per 1,000 overage rows. Growth Small costs $125 for 50,000 rows, with overages at $25 per 10,000; Growth Medium is $250 for 120,000 rows, with overages at $20 per 10,000; Growth Large is $500 for 500,000 rows, with overages at $10 per 10,000.

Paid plans also list beta rows: 150 on Starter Medium, 750 on Starter Large, 3,500 on Growth Small, 8,400 on Growth Medium and 35,000 on Growth Large. MCP access is beta enabled on those plans. Enterprise covers over 4 million rows monthly with custom volume pricing. The pricing page lists monthly prices and does not show annual billing or a discount. Confirm how rows map to calls and how overages are counted before setting a production budget.

Moz API is presented as a hosted API, not as a package to run in your own environment. Moz does not publish a source-availability statement, an open-source licence or self-hosting instructions on the vendor's site. Treat it as a hosted dependency unless Moz confirms otherwise; ask about availability, permitted use and service terms before building a product that depends on its data.

The vendor also does not publish a data-export or migration path for API customers in the published product details. Your application can keep its own records and abstracts around Moz responses, but replacing the provider would still mean sourcing equivalent link and keyword data and adapting the integration. To reduce lock-in, keep provider-specific calls behind an internal interface and confirm whether stored API results can be retained or exported under your contract.

The published free-plan limits are 50 rows per month and one request every 10 seconds. Paid plans raise monthly row allowances, but the vendor's site does not publish a general request-rate limit, uptime target, latency commitment or retry guidance. Confirm how rows are counted, whether rate limits vary by plan, and how the API handles partial failures before using it in a customer-facing workflow.

Moz's website also does not publish security or compliance details for API integrations. Ask about authentication, data handling, retention and applicable compliance commitments before sending sensitive data or making the API part of a regulated workflow. One Reddit thread complained that the free plan changed from 2,500 rows to 50 and described the smaller allowance as inadequate for bulk checks. That is a user report, not a reliability measure, but it highlights the risk of building a bulk workflow around the free tier.
