API, MCP and Looker Studio

Your data belongs to you. WebRank gives you a REST API, an MCP server for AI tools, CSV and JSON exports, and a Looker Studio connector. All of them live on the Developers page.

Your API key#

Open Developers to see the API key of the current workspace. It gives read access to that workspace's data, so keep it private. Choose Create a new API key if it leaks. Anything using the old key (MCP, Looker Studio, scripts, the crawler snippet) stops working until you update it.

REST API#

The base address is https://api.webrank.si. Send your key in the x-api-key header, or as a Bearer token.

curl "https://api.webrank.si/v1/visibility?days=30" \
  -H "x-api-key: YOUR_API_KEY"
Endpoint Returns
GET /v1/visibility?days=30 Overview, leaderboard and trend
GET /v1/prompts Prompt performance
GET /v1/answers?days=30&engine=&limit=100 Raw AI answers with mentions, position, sentiment and cited domains
GET /v1/sources Cited domains and URLs
GET /v1/brands Tracked brands (you and competitors)
GET /v1/crawlers?days=30 AI crawler activity
GET /v1/factcheck The latest FactCheck
GET /v1/rows?days=90 One flat row per answer, for BI tools
GET /v1/export Exports as CSV or JSON

A missing or wrong key returns HTTP 401.

MCP server#

The MCP server lets Claude, Cursor or any MCP client ask about your visibility in plain language. Add this to your client's MCP configuration (in Claude Desktop: Settings, Developer, Edit config). It needs Node.js installed.

{
  "mcpServers": {
    "webrank": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.webrank.si/mcp", "--header", "x-api-key:YOUR_API_KEY"]
    }
  }
}

Available tools: get_visibility, list_prompts, list_answers, get_sources, get_insights, get_crawlers, get_factcheck and get_brands. Then ask, for example: "How did my AI visibility change this month, and which competitor gained most?"

Looker Studio and spreadsheets#

For a quick start without code, download the CSV from the Developers page and import it into Looker Studio or Google Sheets. For a live connection, the Developers page contains a ready-made Google Apps Script community connector: paste it into a new Apps Script project, deploy it, and add the connector link in Looker Studio. Each row is one AI answer.

Warning: The connector script contains your API key. Do not post it publicly.
