Circuit (operating publicly as Spoke; legal entity Circuit Routing Limited) builds last-mile delivery route-optimization software. Its products are Route Planner, a free driver app for uploading stops, optimizing multi-stop routes and navigating; Dispatch, a multi-driver delivery-management platform with route planning, live tracking and proof of delivery for courier operations; and Connect, a marketplace that lets retailers discover local couriers and track deliveries. The Spoke Public API (formerly the Circuit for Teams API) is an HTTP/JSON API that lets teams manage plans, stops, unassigned stops, drivers, depots, routes, members and long-running operations programmatically, optimize and distribute plans across drivers, run full-text stop search with a filtering DSL, and subscribe to webhook events for delivery workflows.
