About this list

15 of our 23 AI rank tracking tools are listed with an API.

Paid plans run from $3 to $97, and 5 have a free or freemium plan.

Last checked 14 October 2026.

Every tool here technically "has an API" per this tag, but when you can actually USE it varies enormously: RankLens ships a documented API for free, forever, no card required; Mangools AI Search Watcher bundles API access into the cheapest standalone entry price in this category ($15.60/month); Morningscore includes its full API on every paid tier from $69/month; and LLMrefs' $0, 7-day trial includes full API access before you pay anything. By contrast, Otterly AI, RankScale and Nightwatch all gate API access to a mid-or-higher tier ($189, $385 and €159/month (about $178) respectively), with no API at all on their cheapest entry plans.
