To get information on a specific tag, the only option is to do a keyword search. This causes issues when they keywords used are used across numerous tags, causing multiple results to be returned.
Being able to search by tag-slug would allow us to be specific about the tag we're looking for.
This is now possible in the Tags V2 API:

Adding an example for context. With the queries in the screenshot, we're trying to grab the info on the toxic-city and the philly tags. As you can see, we have several tags that include those words. And the order in which results are sorted do not seem to be by relevance.
