# Get Uptime Monitor Series

`GET /v1/uptime/monitors/{monitor_id}/series`

Uptime % series (UP / (UP+DOWN)) for the 'Uptime over time' chart, over the last `days`.

Aggregated in SQL so long windows don't pull every check row: daily buckets by default, or
hourly (`bucket=hour`) for the sub-day (24h) window.

## Path parameters

- `monitor_id` string, required

## Query parameters

- `days` integer — Lookback window in days.
- `bucket` string — Aggregation granularity.

## Headers

- `X-API-Key` string, required

## Response `200`

Successful Response

- unknown

## Other responses

## Changes

- **2026-09-03** `aa501502e1fc` — 1 info
  - added the new optional `header` request parameter `X-Organization-Id`
