Ask HN: How to market my API SaaS?

Hello HN!

I’m a developer and I’ve spent the last 5 years building an open source library for WebAuthn (the tech behind Passkeys) called fido2-net-lib [0].

To make adoption even easier (and the workload sustainable) we built an API [1] that really makes the technology easy to adopt and accessible within minutes.

I’ve managed to get both some free and paid customers but I’m struggling with finding an efficient marketing channel/strategy.

I’m here asking for your help. I need all the advice I can get. What can I do to onboard more users and customers?
