Query your data through AI assistants
Pull live SEO and GEO data directly inside your AI tools. Included in every plan.
MCP
Connect SE Ranking to Claude, Cursor, Gemini, or any AI assistant. Ask questions in plain language and get answers powered by live SEO and GEO data.


Pre-built Claude Skills for structured workflows
Use open-source Claude Skills built by SE Ranking to get a finished deliverable without writing long prompts from scratch.
Content brief generator
Takes a domain and topic, runs keyword research, SERP analysis, competitor analysis, and returns a writer-ready brief with an AI Search angle included.
AI Search share of voice
Pulls visibility data across ChatGPT, Perplexity, Gemini, AI Overviews, and AI Mode and returns a share-of-voice heatmap with topic-cluster ownership per competing brand.
Technical SEO audit
Runs a one-shot audit across crawlability, indexability, mobile, security, structured data, and JS rendering, then returns a top-10 fix list ranked by impact and effort.
Fit SE Ranking data into your stack and power your workflows
Use ready-made integrations or build your own setup. No-code and AI-native workflows are both supported out of the box.
Run one-off SEO and GEO research
Analyze backlink profiles, research competitors, track AI search visibility, and more through direct API access or in AI agents via MCP. Fewer manual exports, and more answers faster.
Automate internal workflows
Feed live SEO and GEO data into your existing systems and automate content pipelines, backlink monitoring, client reporting, etc. Run your workflows automatically, at any scale.
Embed data into your platform
Integrate SEO and AI search data directly into your product UI as native features without building your own backend. Improve product engagement and get new monetization opportunities.
Is the API pay-per-use or prepaid?
Both, depending on the plan. Pay as you go is a one-time top-up: buy any credit pack, use it whenever you need it, and the credits never expire. Annual plans are billed upfront for the year, which is what makes the discounted rate possible, up to 57% lower than pay-as-you-go.
Can I test the API on a free trial?
Yes. The 14-day free trial gives you 100K API credits across all six API endpoints, as well as MCP server access. You also get access to the complete SEO and GEO suite by SE Ranking. No credit card required.
Do unused credits roll over?
It depends on the plan:
- Pay-as-you-go credits never expire. Buy a 250K pack today and use it two years from now.
- On annual plans (standalone and add-on), credits are provided upfront and expire at the end of the billing cycle. Unused credits don’t carry over. Any additional top-ups purchased on top of a subscription never expire.
- Free trial credits expire at the end of your 14-day window.
What is a "credit" and how much does each call cost?
Credits are the unit that SE Ranking uses to measure API usage. Every successful call consumes credits from your balance. Failed requests are not charged. Costs vary by endpoint and are applied in one of two ways: a fixed number of credits per successful request, or a variable number of credits per record returned. See the full breakdown here.
What's the difference between the Data API and the Project API?
The Data API gives you raw SEO data on demand, including keyword volumes, backlink profiles, AI Search results, site audit data, and more. It’s charged in credits. The Project API manages your SE Ranking workspace: create projects, add keywords to tracking, schedule audits, pull reports. It draws on your subscription project limits, not credits.
As a rule of thumb: use the Data API for ad-hoc queries and AI agents; use the Project API for ongoing tracking of a fixed list of keywords or sites.
How quickly can I get an API key after purchase?
Instantly. Your API key is issued immediately after payment. If you are on a free trial, you’ll get an API key once you confirm your email. Find your keys within the API dashboard.
Do credits reset each month, or is the balance cumulative?
On annual plans, credits are provided upfront for the billing cycle and expire at the end of it. Unused credits don’t carry over to the next cycle. On Pay as you go, the balance is fully cumulative. Every top-up adds to your total with no expiry.
