Preview Sample Data

Before applying policies or creating reports, it’s useful to see a slice of the data itself. This API retrieves up to the first 100 rows of an asset. For example, a data engineer can validate that the “orders” table contains recent transactions before applying a freshness check.

⚠️ All endpoints require authentication. See Authentication & Headers.
