What we do

We know businesses want to integrate to their communications. We see them leave the providers that don't give them an answer. Don't lose your customers. Let Zilkr help.

Zilkr turns any communication company's platform into external Integration APIs while managing the Developer Program. Zilkr also seeds the ecosystem with products and partnerships.

Free for Developers


Think of Zilkr like Twilio, but instead of buying numbers and then using APIs, you use APIs first and let us do the work of finding numbers that want your app. Zilkr works directly with phone companies so their customers see, choose and use the apps and integrations you build here.

Zilkr's API is super simple. It is is a collection of HTTPS-only, REST-based methods that take structured JSON content. And we guarantee a network-neutral definition regardless of the phone companies we connect with.
