Retrieve a small preview of an audience so you can validate it before exporting. This is a capped, redacted teaser, not a data feed: it returns up to 25 rows carrying firmographics, role, intent, first name, and the HEM match key, plus has_* flags indicating which contact fields exist. Raw contact data (emails, phones, LinkedIn, personal address, full name) is NOT returned here; download/unload the audience to get (and be billed for) the full contact records. total_count reports the audience's true size regardless of the sample size.
