A line item is the exchange-level serving object under a campaign: bid, daily and lifetime budgets, pacing, targeting attachment, and creative associations. Traders edit line items all day. Adprime Zero buyers create a campaign. The product compiles the line item.
You should not invent a numeric line-item ID in a prompt. The API returns Adprime Zero campaign IDs. If a tool asks for a Beeswax line item, something has left the public path.
Details that live on the line item still leak into product behavior. Daily budget cannot exceed lifetime on the exchange. Plain CPM will not accept pacing. CPM_PACED plus pacing: daily will. Lifetime pacing wants an end date, which an uncapped prepaid campaign may not have. Those facts are in the pacing entry and the exchange pacing changelog.
Activation order on the exchange is picky: inactive campaign and line item, targeting attached, creative associated, then active. The product owns that sequence so an agent does not have to.
