Use a focused free tool to prepare your first report, then carry the request into a FlexQueries workspace when you are ready.
One platform for classic SEO and AI-search
Connect the sources you already use — FlexQueries unifies organic and AI-search data behind the scenes.
Every project and metric — organic and AI — on one screen, no silos.
See exactly which sources AI engines cite for the queries that matter.
Know exactly what every run costs. No subscription, no seat pricing, and no automatic usage overages.
Your spend should follow the work you run.
Every paid data request is metered and shown against your dollar balance. When the balance runs out, the action stops instead of creating a surprise bill. Add funds only when the work calls for them; the unused balance never expires.
Search intelligence, reinvented
Pay for runs, not seats
There is no plan or monthly fee. Add funds when you need them, then spend your balance only on the actions you run. Unused funds never expire, with no per-seat fees or annual contract.
20 backlink checks
Core SEO and AI visibility without a monthly plan

Questions
What can I do in FlexQueries?
Research keywords and SERPs, analyze domains and backlinks, run site audits, track rankings, investigate AI-search visibility, review web mentions, and connect the same research tools to an AI agent through MCP.
How does pay-as-you-go billing work?
Your account has a dollar balance. The app estimates paid actions before they run and settles the final cost against your balance. There is no subscription or seat fee, and you can add funds whenever your balance needs a boost.
What happens when ongoing tracking runs out of funds?
Scheduled tracking only continues while the account has enough balance. You can enable automatic top-ups to keep it running, or add funds manually when you are ready to resume.
Can my AI agent use FlexQueries?
Yes. FlexQueries MCP gives supported AI clients authenticated tools for keyword, SERP, domain, backlink, rank-tracking, audit, local, and Search Console workflows.
Is there a free trial or subscription?
There is no subscription or monthly plan. Eligible new accounts receive $1.00 in balance without a card, so you can try a few workflows before adding funds.
