WHAT YOU CAN ASK

Ask in plain language. Get structured JSON.

Each is one call against the endpoint, ask in plain English through the MCP, or hit the API directly. Same key, same credit balance.

You ask“How often does AI recommend my brand?”

You get{ "mention_rate": 0.71, "avg_position": 2.3 }

You ask“Which model ranks me best, which worst?”

You get{ "by_model": { "chatgpt": 0.82, "gemini": 0.41 } }

You ask“What’s my share of voice vs the field?”

You get{ "share_of_voice": 0.28, "leader": 0.44 }

Why rank tracking broke

In AI search, you track brand mentions, not blue links.

A buyer no longer scrolls a page of ten links and clicks one. They ask ChatGPT or Gemini for the best tool in your category and read the names the model hands back. Your position 3 on Google is irrelevant if the answer above the fold never says your name. The metric that matters moved from which URL ranks to how often a model names you, where in the list, and how big your slice of the field is.

One call to /v1/rankings passes your brand plus a prompt set to ChatGPT, Claude, Perplexity, and Gemini at once and returns that exact shape: mention rate, average position, share of voice, and a per-model breakdown, as JSON.

Mention rate: of N prompts, how many named your brand at all.
Average position: when named, how high in the list you land.
Share of voice: your mentions as a fraction of the whole field.
by_model: the same three metrics, split per AI model.

Every model, one API key.

One call reaches all 4 AI models, ChatGPT, Claude, Perplexity, and Gemini, or pass “models” to narrow to the ones you need. Billed per model queried.

vs. a Google rank tracker

A rank tracker watches the search engine your buyers stopped using.

A classic SEO rank tracker reports where your URL sits in Google's ten blue links. But the answer your buyer reads now comes from an AI model that recommends brands by name and rarely shows a ranked list at all. Same goal, brand visibility, measured on the surface that matters.

	Cite42	Google rank tracker
What it measures	Brand mention rate, position, and share of voice	Which URL ranks where in ten blue links
Coverage	ChatGPT, Claude, Perplexity, and Gemini in one call	Google SERP only, the surface buyers are leaving
Per-model view	by_model breakdown, see where you rank well vs poorly	One engine, no model-level signal
Integration	MCP-native + REST, your agent calls it directly	Dashboard export or a scraping add-on you wire up
Billing	Pay per model per call, $25 minimum that never expires	Monthly seat subscription whether you check or not
Repeat checks	Identical prompt sets replay from cache at $0	Same fixed monthly bill regardless of usage

QUESTIONS

Questions about ai brand rankings.

A Google rank tracker tells you which URL ranks where. AI search visibility tells you which *brand* gets mentioned, and AI answers don't link to ranked URLs the same way. The right metric is mention rate × position × share-of-voice, not a top-10 list.

Close, not identical. Cite42 uses each model's official API with web search enabled. API-mode responses correlate strongly with consumer-mode for category prompts (which is what brand tracking cares about). Consumer mode adds personalization and memory that the API can't replicate.

Four: ChatGPT, Claude, Perplexity, and Gemini. Each call fans out to all four and returns a per-model breakdown, so you can see where a brand ranks well on one model but poorly on another, they pull from different ranking signals.

Each /v1/rankings call is $0.07 per model per call, $0.28 for a full sweep across all four, or $0.07 if you only care about ChatGPT. 20 prompts across all four models = $5.60 for one full sweep; a daily 10-prompt single-model check is just $0.70/day, vs the monthly subscription floors charged by incumbent platforms.

Yes. Install the Cite42 MCP server in Claude Code, Claude.ai, Cursor, or Codex. Then ask "Track 'mybrand' daily across these 20 prompts in ChatGPT and Claude." The agent picks the right tool and reports back.
