Current AI-visibility score (0–100) + per-engine breakdown (ChatGPT, Perplexity, Claude, Gemini) + the top competitor appearing in your place. Pro subscribers also get `trend`: 7- and 30-day score movement from stored snapshot history for the question this audit asked, ending at its snapshot and co…
run_audit
Full one-time audit → category scores (AI visibility, SEO, security, performance) + top issues + a shareable report URL.
get_changes
What changed in the AI-visibility score — the change in the overall score and the per-engine score changes, for engines measured both times, the overall only when the same engines answered both snapshots (else it is null with an `overall_note` naming which answered each, and the per-engine changes…
compare_competitors
Head-to-head AI-visibility ranking against named competitor domains + where each appears that you don't. Quota-aware: caps the audit fan-out to your remaining daily quota, reuses recent cached audits, and reports any competitors it had to skip rather than dropping them silently.
track_site
Start (or stop) weekly monitoring of a site's AI visibility. Its weekly re-audits join the history `get_changes` reads from, which audits accrue tracked or not — monitoring watches a site, it does not enable `get_changes`.
untrack_site
Stop monitoring a site and free up a monitoring slot. Idempotent.
list_tracked_sites
List the sites you're monitoring, with cadence, active state, and slots used/remaining.
get_monitoring_status
A glanceable dashboard across all tracked sites — latest score of each site's series (the series `get_changes` reads), the date of each one's last scheduled run and when the next runs, and the most recent like-for-like change (or a note, or the summary, saying why there is none), shown as its per-e…
check_upgrade_status
Your own subscription standing — tier, status, period end, and what upgrading unlocks (starting Pro requires a payment method and accepting the Terms). Consumes no audit quota.
