 - [Route API Reference](./turn-by-turn/api-reference.md) - The structure of API requests and responses to a Valhalla routing service is described here. This shows the JSON inputs and describes the JSON responses to form routes and directions.
 - [Matrix API Reference](./matrix/api-reference.md) - The structure of API requests and responses to a Valhalla time distance matrix service is described here. This shows the JSON inputs and describes the JSON responses to retrieve times and distances between locations.
-- [Optimized Route API Reference](./optimized_route/api-reference.md) - The structure of API requests and responses to a Valhalla optimized route service is described here. This shows the JSON inputs and describes the JSON responses to retrieve the route which optimizes the path through the input locations. This is essentially the Traveling Salesman Problem (TSP)
