# Get Facebook Page demographics

`GET /v1/analytics/facebook/demographics`

## Request

- Base URL: `https://zernio.com/api`
- URL: `https://zernio.com/api/v1/analytics/facebook/demographics`
- Auth: HTTP bearer

Returns the follower breakdown of a connected Facebook Page by country and/or city, from Meta's latest daily snapshot.
Country keys are ISO 3166-1 alpha-2 codes; city keys are "City, Region, Country" strings as Meta returns them.
Meta removed age and gender demographics for Pages (page_fans_gender_age) on November 15 2025 with no replacement, so only country and city are available.
Meta reports small counts at a privacy floor, so the long tail can show identical low values. Requires the Analytics add-on.

## Query parameters

- `accountId` string, required
- `breakdown` string

## Response `200`
