Steps
Call GET /api/v1/query with from and to as Unix epoch seconds and a query string in Datadog's metric query syntax.
Authenticate with the DD-API-KEY header.
Use the regional API host that matches your Datadog site (e.g. api.datadoghq.com, api.datadoghq.eu, api.us3.datadoghq.com), since metric data doesn't cross site boundaries.
Read the returned series' pointlist for the timestamp/value pairs Datadog computed for the requested window.
Combine with GET /api/v1/metrics/{metric_name} to check a metric's metadata (unit, type, description) alongside its queried values.
Known gotchas
This is a legacy, metrics-only endpoint — it doesn't span other Datadog products the way the newer v2 query endpoints (query/timeseries, query/scalar) do.
As the query window widens, a graph can only contain a set number of points, so Datadog aggregates points together to stay under that ceiling and raw resolution degrades for long time ranges.
