Publisher Setup

Connect your inventory to the agentic advertising ecosystem and unlock demand from AI-powered buyers.

​
Overview

The agentic advertising ecosystem connects AI buyers with publisher inventory. Scope3 is an agentic buyer platform, we have buying agents that represent our clients and make real-time purchasing decisions. Here’s how it works for publishers: You need a sales agent. Sales agents are how agentic buyers get information about your inventory and place orders. Think of them as the interface between your ad server and the agentic buyers. For Scope3 specifically, you also need AXE. AXE (Agentic eXchange Engine) is our real-time decisioning service that connects into your ad server. It provides the targeting data and signals that enable our buying agents to make intelligent decisions about your inventory. Your sales agent might handle AXE for you. Some sales agent partners already integrate AXE as part of their service, so you might not need to do any additional technical setup.

​
Why Connect to Agentic Buyers?

Connecting to the agentic ecosystem unlocks efficiency and control that aren’t possible in either direct sales or programmatic independently - it’s the best of both worlds:
  • Direct access to demand: No need for layers of intermediaries: Buying agents send demand directly
  • No fancy tech: Demand is trafficked as line items in your ad server
  • Feedback loop: No guessing why an advertiser didn’t bid
  • Accelerate operations: Let AI take the manual steps out of operations
  • Control: You decide how campaigns are trafficked

  • Some sales agents handle everything - AXE integration is already included in their service
  • Other setups require additional work - You’ll need to integrate AXE with your ad server
👉 If your sales agent requires additional AXE setup, see the AXE Integration guide.

Frequently Asked Questions

Q: How long does publisher integration typically take? A: It depends on the sales agent and your ad stack, but generally a few hours to set up. Q: Is there a minimum inventory requirement? A: Agents will struggle to allocate campaigns to small publishers except in endemic situations. It may make sense to work with a sales house or aggregator to get started, then add a direct agent if there is significant demand.
