About Zinc

Zinc is building the programmable commerce layer for the internet. Our API already enables tens of thousands of transactions each month, and our goal is much bigger: a world where any purchase online can be automated and integrated through a simple API.

As commerce shifts to automation, AI, and agents, the purchasing layer of the internet will become essential infrastructure. You will have a direct hand in building it.
