# Stack Overflow User Tags API

How much one user asks and answers under each tag, with counts and total scores.

`GET /v1/stack-overflow/users/{memberId}/tags` returns the tags a user posts under, most active first. Each row has `tag`, `questionCount` and `questionScore` for questions the user asked with the tag, and `answerCount` and `answerScore` for answers the user gave on questions with it.

The route is useful for a skills profile or for matching a user to a topic. Page with `page.nextCursor` while `page.hasMore` is true. A user with no tag activity is `found` with an empty list; a user id that does not exist is `not_found`.

## FAQ

### What do the four counts mean?

questionCount and questionScore cover questions the user asked with the tag. answerCount and answerScore cover answers the user gave on questions that carry it.

### How many credits does a page cost?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth. Each paginated page is a separate billed request.

### Is the list sorted?

Yes, most active first. Use the counts to see whether the activity is mostly questions or answers.

### How is an empty list different from not_found?

A real user with no tag activity is lookupStatus found with data.tags empty. A user id that does not exist is lookupStatus not_found.
