# citation-tracker

> Checks whether current AI search assistants (Perplexity, ChatGPT, Claude, Gemini) cite your target domains for a prompt, and whether ChatGPT's first search names your brand. A GEO/AEO visibility check, not a rank tracker.

## Tools

- **citation_tracker_check** ($0.75/call): Sends one prompt to 1 to 4 search assistants (Perplexity, OpenAI, Anthropic, Gemini) and reports whether each cites your target domains: cited status, citation count, cited domains, model, and a structured error per engine. Started concurrently; a failed engine returns `cited: null` and does not block the others (PD7). Paid, $0.75/call; read-only and safe to retry.
- **citation_tracker_check_perplexity** ($0/call): Sends one prompt to Perplexity (sonar) and reports whether it cites your target domains, with citation count and cited domains. Free: one call per caller and 100 calls total per UTC day; both limits fail closed. A real live evaluation before you pay for citation_tracker_check.
- **citation_tracker_shortlist_gate** ($0.2/call): Checks whether ChatGPT would search the web for one prompt and whether its first search query names any of your supplied brand or product terms (whole-word match). Use it to gate a prompt before spending on citation_tracker_check. Paid, $0.20/call; read-only and safe to retry.
