SE Ranking
Connect SE Ranking to research keywords, domains and backlinks, track rankings, run site audits, and check your visibility in AI search.
You paste one SE Ranking API key, from API, Dashboard in your account. The same key opens keyword, domain and backlink data, your projects, Local Marketing and SE Visible, as far as your plan includes them.
- Setup time
- 2 min
- Auth
- API credentials
- API base URL
- https://api.seranking.com
- Rate limits
- Per key, over a rolling second: 10 requests a second on the Data API, and 5 on the Project API. Data API trial accounts get 1 a second. Over the limit, SE Ranking answers HTTP 429, and repeated overruns on the Project API lock the key for 10 minutes or longer. PopMCP spaces out its calls on each key.
Before you begin
- An SE Ranking account on a current plan: Essential, Pro, Business, Core, Growth or Enterprise. All of them include the API. Trial accounts work too, limited to 1 data request a second.
- The main account login. API access lives with the main account, so on a sub-account ask your account administrator for the key.
- API credits for data tools. Every plan includes a monthly allowance, from 10,000 on Essential to 100,000 on Business, Growth and Enterprise.

Copy a key, or create one for PopMCP
Copy a key from the API Keys table. To keep PopMCP on its own key, click + CREATE API KEY at the top right, enter a name like PopMCP under API key name, then click CREATE KEY. The new key appears in the table, ready to copy. There is no separate key per product, so one is enough.
API Dashboard
Paste the key into PopMCP
Paste it into SE Ranking API key. PopMCP checks it with three free calls, which spend no credits, and tells you what the key reaches and how many credits are left.
Connect in PopMCP
Open your workspace, choose SE Ranking in the marketplace, and fill in the connect dialog:
| Field | What to enter |
|---|---|
| SE Ranking API keysecret | From API > Dashboard in SE Ranking: copy a key from the API Keys table, or click Create API key. Stored encrypted, used server-side only.Encrypted with AES-256-GCM on save and never shown again. |
PopMCP verifies the credential against SE Ranking immediately. On success the connection flips to Verified and its MCP tools are provisioned.
Verify it worked
PopMCP shows SE Ranking as Verified, labelled with your name and email, and lists what the key reaches. Ask for your projects: seranking_list_projects answers with each project's id and name. Ask about any domain to try the data side: seranking_check_domain spends about 215 credits.
Troubleshooting
"SE Ranking didn't accept this key"
Why: The key was copied incompletely or has been deleted, or it belongs to a sub-account.
Fix: Copy it again from API, Dashboard, or create a new one there. On a sub-account, ask your account administrator for the key.
"SE Ranking knows this key, but the subscription behind it has ended"
Why: The plan has lapsed.
Fix: Check Profile & Preferences, Billing in SE Ranking, then connect again.
A tool answers Insufficient funds
Why: The account is out of API credits. Project, Local Marketing and SE Visible tools keep working.
Fix: Add credits on the Subscription page in SE Ranking, or wait for the monthly allowance.
A tool answers 429 Too Many Requests
Why: Something else is sharing this key, as limits count per key. PopMCP spaces out its own calls.
Fix: Wait a moment and try again. Repeated overruns can lock a key for 10 minutes or longer, so give busy scripts their own key.
A domain returns nothing
Why: SE Ranking has no data for it, or it is one of the very large sites the API doesn't serve, such as google.com.
Fix: Try a smaller domain, or a different country with source.
A tool answers that this key can't use that
Why: Your plan may not include that product, or the project belongs to another account.
Fix: seranking_connection_profile shows what the key reaches. Check the plan under Billing in SE Ranking.
