# List Niche Categories

`GET /api/v1/categories`

## Request

- Base URL: `https://viraloutliers.com`
- URL: `https://viraloutliers.com/api/v1/categories`
- Auth: HTTP bearer

Returns the curated niche taxonomy (up to four levels, e.g. "Health > Exercise > Gym") with, for each category, its id, path, level, parent and how many active profiles are categorized under it including its sub-niches. Only categories with at least minProfiles profiles in their subtree are returned (default 5), so every id you get back yields a real result set. Pass a categoryId to search_outliers, search_profiles or niche_trends to scope them to the creators in that niche; the filter always covers the subtree. Free to call and cached, so call it at the start of a session and reuse the ids. Categories are assigned per creator by our categorizer (reviewed by hand for new niches), which makes this filter more precise than a keyword over captions: it catches creators whose captions are hashtag-only or not in English.

Cost: free.

## Query parameters

- `minProfiles` number
- `maxLevel` number

## Response `200`

Success

- object

## Other responses

- `401`: Invalid or revoked API key (or, on free skills, no key sent); code key_suspended means the key was suspended when its account was claimed by the email owner and can be reactivated in Settings
- `402`: Payment required. Without an API key (billable skills only) the code is payment_required and error.payment.checkoutUrl (or, when no link is configured, error.payment.pageUrl at https://viraloutliers.com/api-access) buys a key without an account; with a key it is insufficient_credits and error.payment points at create_topup_link.
- `429`: Rate limited
