The AI brand-monitoring MCP + API: track prompts daily, get pinged when they move. No monitoring product to pay for.
One-off rank checks are easy. Catching the moment a competitor takes your slot in ChatGPT takes daily monitoring, and that loop is just a scheduled call plus a diff. Cron /v1/rankings (or /v1/compare for a whole field) and compare runs, or tell your MCP agent to "watch these 20 prompts daily and ping me when my mention rate drops." Same pay-per-call price, no separate monitoring tier.

1. You ask your AI, in plain English Watch penflow across my 20 prompts every morning. 2. Cite42 re-runs the set on every model, daily → ChatGPT · Claude · Perplexity · Gemini 3. You get pinged only when something moves mention_rate 0.71 → 0.58 — competitor took 3 slots.
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.
{ "mention_rate": 0.58, "change": -0.13, "alert": true }{ "by_model": { "chatgpt": -0.18, "claude": 0.00 } }{ "overtaken_by": ["northcrm"], "prompts": 3 }Monitoring AI brand mentions is a cron job and a diff, not a product.
A one-off rank check tells you where you stand today. Catching the morning a competitor takes your slot in ChatGPT takes the same prompts run on a schedule and compared against yesterday. That loop is the entire job, and it is two primitives you already have: a scheduled call and a diff.
So Cite42 doesn't sell a monitoring tier. /v1/rankings re-runs your prompt set across ChatGPT, Claude, Perplexity, and Gemini for $0.07 per model per call, and /v1/compare does the same against a whole competitor field. Cron it, diff the runs, alert on a delta that crosses your threshold, wire the alert into wherever you already work. Or hand the loop to your MCP agent and tell it to watch 20 prompts daily and ping you when your mention rate drops.
- A 20-prompt daily sweep across all four models is $5.60/day; narrow to ChatGPT alone and it is $1.40/day.
- Diff mention_rate run-over-run to catch a competitor_overtake the morning it happens.
- Identical prompts replay from the cross-customer cache at $0, so a quiet day costs nothing.
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.

Pay per sweep you actually run, not a flat monthly floor.
GEO monitoring platforms bundle scheduling, alerts, and a dashboard into a monthly seat you renew whether you swept once or every hour. The underlying work, re-run prompts and diff the results, is a few lines of cron against a data API. Same daily answer, no subscription floor.
| Cite42 | Monthly monitoring subscription | |
|---|---|---|
| Integration | One endpoint, one key; cron /v1/rankings and diff the runs | A dashboard and a seat; their schedule, their UI |
| Coverage | ChatGPT, Claude, Perplexity, and Gemini in one sweep | Whatever models the tier includes, often gated by plan |
| Alerts | You own the trigger, fire to Slack, your DB, or PagerDuty | Built-in alerts, but only where the vendor lets them go |
| Billing | $0.07 per model per call, pay only for sweeps you run | Flat monthly floor whether you swept once or never |
| Repeat queries | Quiet day? Identical prompts replay from cache at $0 | Flat fee regardless of how little moved |
| Cost, daily 20-prompt sweep | $5.60/day across four models, or $1.40/day on ChatGPT alone | Monthly seat priced for the platform, not your usage |
Pay per call. $25 minimum deposit. Credits never expire.
