ZenithSearch is free. Full stop.
There's no paywall, no locked tier, no 'upgrade to unlock this endpoint.' Every feature on this site — search, the API, all of it — is free to use.
This is a passion project.
ZenithSearch started, and continues to run, on a budget of exactly $0. No investors, no revenue targets — just a small amount of free time spent on YuNet, SFace, and Faiss because the problem was interesting.
If you find it useful and want to leave something, that donation isn't payment for a feature — it's just a thank-you. Every dollar today is put toward covering VPS hosting costs.

A small, one-time thank-you. This is the suggested amount if you just want to say 'nice work.'
