# New API: aggregated RUM metric data

You can now **query aggregated RUM metric data** via [API](https://support.speedcurve.com/reference/queries#/) — the same way your **Favorite charts** work in the SpeedCurve UI.

This new [Queries API](https://support.speedcurve.com/reference/queries#/) lets you:

* Retrieve **timeline or single-value chart data** for any RUM metric using an existing chart ID.
* Control **time granularity** with a `bucket_size` parameter — from **10 minutes to 31 days**.
* Receive up to **200 data points** per query.
* Track progress with a **two-step workflow**:
  1. `POST /accounts/{account_id}/queries/` — submit your query
  2. `GET /accounts/{account_id}/queries/{query_id}/` — poll for results

**Key details:**

* Works exclusively with **RUM data** (synthetic metrics are excluded).
* Requires charts created in the SpeedCurve UI (`timeseries`, `budget`, or `value` types).
* Supports both **default** and **custom bucket sizes**
* Returns aggregated values (e.g. 75th percentile) and number of page views per time bucket.

Ideal for teams looking to integrate RUM data into external tools or perform custom trend analysis.
