The pricing is on per API call basis.
Skills Profiler Plugin
Rendering the Skills in the frontend for users to select skills can be a tough challenge. We have developed a frontend - the one you saw above that helps you overcome this challenge. Users can easily search, select and rate on skills.
The intuitive frontend leads users to other skills that could be relevant for them based on their activity. The plugin is in JS and can be implemented in most application stacks.
