You can now query aggregated RUM metric data via API — the same way your Favorite charts work in the SpeedCurve UI.

This new Queries API 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.
