## Query parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `startDate` | string | yes | The first day of the range (UTC), for example `2026-10-01`. The day counts. |
| `endDate` | string | yes | The last day of the range (UTC). The day counts, so `startDate` = `endDate` is one day. The range may hold at most 366 days, or 31 days for an `hourly` series. |
| `granularity` | hourly \\| daily \\| weekly \\| monthly | no | The length of one `period`. A week starts on Sunday. Default: `daily`. |
| `integrationType` | spotify \\| appleMusic \\| youtube \\| tidal \\| resso \\| boomplay \\| amazonMusic \\| deezer \\| pandora \\| soundCloud \\| youtubeMusic \\| napster \\| qobuz \\| qqMusic \\| yandexMusic \\| vkMusic \\| anghami \\| zvuk \\| gaana \\| jiosaavn \\| audiomack | no | Count only the requests for this music service. Leave it out for every service. |

## Response 200

One row for each period with requests, oldest first.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `data` | object[] | yes |  |
| `data[].period` | string | yes | The start of the period in UTC, `YYYY-MM-DD hh:mm:ss`. |
| `data[].unique_users` | string | yes | Connected users that made at least one request in the period. A decimal string, so a large count stays exact. |

```json

  "data": [

      "period": "2026-10-01 00:00:00",
      "unique_users": "string"

  ]
}
```

## Errors

- 400: A date is missing or not valid, `endDate` is before `startDate`, or the range is too long.
- 401: The request has no credentials.
- 403: The request does not use Client Secret authentication.
- 429: Your account sent more calls this minute than its rate limit allows.
