Kardinal Information

Kardinal is the route optimization API for developers and their agents. For ten years, we've solved the hardest logistics optimization problems, the ones generic tools quietly fail on: real-world constraints, complex operations, results that actually hold in the field. That depth is now available as an API, self-serve, with transparent pricing among the most competitive on the market, and a free tier. We built it to be read and called by machines as much as by people. Software is now built with AI agents that read the docs, pick tools and call them, so the building blocks have to be consumable by those agents. And on hard combinatorial problems, reasoning is not enough: agents need a deterministic answer they can act on, not a plausible one. Two ways to work with us: our API, for teams that integrate on their own, in full autonomy; our experts, for those who'd rather build it with us. Either way, the same engine, ten years of hard cases proven in production. Trusted by carriers, shippers and delivery networks. Recognized as a Representative Vendor in the 2026 Gartner Market Guide for Vehicle Routing and Scheduling. Give your agents facts to reason on.
