Getting started
Get a key, connect your agent over MCP or call the REST API, and ask five AI engines whether they cite your site.
Geondex asks Perplexity, ChatGPT, Claude, Gemini and Grok the question a buyer would ask, each with web search on, and tells you whether your site is cited, at what position, and who is cited instead. Each engine runs the model its own consumer app uses by default, or a fast model from the same provider where that one is too slow; for some engines you can pick a stronger model. It stores each answer, so the next identical check comes back with what changed.
You use it from your agent through the MCP server, or from any script through the REST API. Both expose the same seven calls and return the same JSON.
Quickstart
- Sign in with Google and create a key on your account page. Keys start with
gx_. - Install the MCP server in Claude Code, Cursor, VS Code, Windsurf, Codex or Claude Desktop, or use the REST API.
- Ask: "Check mysite.com for 'best X for Y' on all five engines."
- Ask again next week. The delta comes back with the answer.

Your first call over HTTP
Replace gx_YOUR_KEY with your key. GET /me is free and shows your balance:
curl -s https://geondex.com/api/v1/me -H "Authorization: Bearer gx_YOUR_KEY"Then run a check. It costs each engine's model credits, only for engines that answer — all five defaults together are 57:
curl -s https://geondex.com/api/v1/check -H "Authorization: Bearer gx_YOUR_KEY" -H "content-type: application/json" -d '{"domain":"ttsensei.com","prompt":"best table tennis blade for beginners"}'Where to go next
- How a check works: what "cited", "position" and the delta mean, and what every response looks like.
- Authentication: keys, headers and the free
GET /me. - Credits & pricing rules: what each call costs and when credits reset.
- Errors & rate limits: every
error.codeand what to do about it. - API reference: one page per endpoint, with a full request and response.
- MCP server and agent skills: let your agent make the calls.
