# Compare Profiles Head-to-Head

`POST /api/v1/profiles/compare`

## Request

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

Compares 2–5 tracked profiles (by profile id or platform+handle) and returns each one's stats (follower count, average views/likes across time windows, engagement rate) plus a computed ranking flagging the top performer by followers and by engagement. Pure lookup, fast. Unresolved profiles come back in a notFound list rather than failing the call.

Cost: 2 credits per call.

## Request body

- object
  - `profileIds` string[]: Profile ids to compare (from search).
  - `handles` string: Handle pairs to resolve, e.g. [{"platform":"tiktok","handle":"x"}]. 2–5 profiles total across both fields.

## 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
