Twinword Category Recommendation API

Twinword creates tools to collect data describing the ways in which people associate concepts. The tools include word association tests, the word graph dictionary, e-commerce recommendations, document detection, and more. Twinword provides a series of APIs that expose some of these tools.
The Twinword Category Recommendation API is a web service for e-commerce sites. Developers use a simple GET call to pass a product category, and the API responds with a weighted list of related categories. The API can also be mapped to partner product categories.
