Before you ask.
What counts as a query?
One call to /v1/search. Multi-probe internals are free —
we don't charge for the fact that we do more work to get better
recall. Batch endpoints count one query per input item.
What if I exceed the monthly cap?
We don't cut you off. Overages are billed at $0.25 / 1 000
queries on Starter and $0.10 / 1 000 on Pro.
We email you at 80% and 100% so nothing surprises you.
Can I self-host?
Yes — Enterprise tier. You get the Rust binary (Linux x86_64 / arm64, macOS arm64, Windows x86_64), a signed license file, and a support contract. The patent license is bundled.
Is there a free trial for Pro?
14 days, no card required. You'll see the full Pro dashboard, keys, and quotas. If you decide not to upgrade, your account quietly reverts to Free.
How is my data handled?
Indexes are stored hashed — the engine never holds your raw strings. Hashes are per-account and salted. Backups are encrypted at rest (AES-256). We're working on SOC-2 Type II for Pro and above.
Can I change plans later?
Yes, anytime. Upgrades are prorated to the day. Downgrades take effect at the end of your current billing period. You keep all your data, keys, and indexes through every transition.
Do you offer academic discounts?
Pro is free for verified academic use (.edu email or ORCID).
Just email info@mirrorfractal.com after signing up
and we'll flip the flag on your account.
