# Stack Overflow Tag API

One tag with its description, synonyms, related tags and best answerers.

`GET /v1/stack-overflow/tags/{tag}` returns one tag. `include` picks which parts come back, each of which adds to the response time: `wiki` for `excerpt`, `bodyHtml`, `excerptEditedAt` and `bodyEditedAt`, `synonyms` for `fromTag`, `toTag`, `appliedCount`, `createdAt` and `lastAppliedAt`, `related` for the tags used together with it, and `topAnswerers` for the best answerers of all time with `user`, `postCount` and `score`. All four are on by default.

A synonym resolves to its canonical tag, so `python3` comes back as `python` and `py` as `python`. A tag that nobody uses is `not_found` with `tag` null. Encode `#` and `+` in the path as `c%23` and `c%2B%2B`. `synonymsComplete` is false when the tag has more synonyms than one response holds.

## FAQ

### How do I get only the tag counts?

Set include= to a part list without the extras. The tag itself comes back with its name, questionCount, synonyms, moderator-only and required flags and last activity, and the other parts are null.

### How many credits does a tag lookup 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.

### What happens when I ask for a synonym?

The lookup follows it to the canonical tag. python3 resolves to python and py resolves to python, so the tag name in the response can differ from the one you sent.

### Why is synonymsComplete false?

The tag has more than 100 synonyms and the list stops at the ceiling. The synonyms that came back are still in synonyms.
