Publisher Integration FAQ

Common questions from publishers integrating with Scope3’s agentic advertising platform.

​
AXE Integration

​
How are segments defined and activated?

Each segment maps to a campaign set up by an agentic buyer in the Scope3 platform. When we set up an order for a campaign, we map it to the appropriate segment. Segment Glossary:
  • axei - Inclusion segment (1P audience matching)
  • axex - Exclusion segments (brand safety blocks)
  • axem - Creative macros passed into the creative

​
How are segments used in the ad server?

Segments are passed as key-value pairs to your ad server (typically via Prebid). You set up line items targeting these segments, and the ad server uses them for inventory matching and delivery.

​
What is the expected impact on the ads ecosystem?

Publishers integrating with Scope3 typically see:
  • More demand - Access to AI-powered buyer agents
  • Higher CPMs - Premium pricing from direct buyer connections
  • Better ad quality - More control through brand standards and safety rules
  • Direct buyer relationships - Reduced intermediary fees

​
Is AXE required to integrate with Scope3?

Yes, AXE (Agentic eXchange Engine) is required to integrate with Scope3 through a sales agent. Other buyers may not require it or may have their own integration methods.

​
How do we get a data flow diagram for AXE?

See the AXE Integration Data Flow section for a complete diagram showing how segments flow from buyer agents through AXE to your ad server.

​
Sales Agent Integration

​
Do we need to integrate with a sales agent?

Yes, a sales agent is required to connect your inventory to the Scope3 agentic ecosystem. The sales agent acts as the bridge between your ad server and AI buyer agents.

​
How do we get integrated with a sales agent?

Several options are available:
  1. Commercial Solutions:
  2. Open Source:
  3. Build Your Own:

​
Is the buyer’s agent the same as the seller agent?

No:
  • Buyer’s agent - Like a DSP, represents the advertiser
  • Seller agent - Like an SSP/Prebid, represents the publisher

​
Does Scope3 provide both the seller agent and AXE?

Scope3 is the buyer platform and provides AXE for real-time data. We host an open-source sales agent to help publishers get on board, but you can use any compatible sales agent.

​
Signal Agent Integration

​
What other integrations are needed besides Prebid and GAM?

Beyond the basic AXE integration, you may want to:
  1. Map your data - Audience segments and contextual data (weather, etc.)
  2. Define products - Create a media product catalog
  3. Set pricing - Configure your pricing model
  4. Build custom agents (optional) - Custom targeting or pricing logic

​
Do publishers need a seller agent to get value from signal agents?

Yes, the sales agent sets up campaigns as line items in your ad server. The flow is: Offline (Campaign Setup): 
Signal Agents → Scope3 Data Attachment API → Scope3 Platform
→ AXE Sync + Sales Agent → Ad Server (line items created)
Real-time (Ad Serving): 
Ad Server → Prebid → AXE (matches with pre-synced data) → Returns segments
→ Ad Server matches line items → Delivers creative with macros

​
What enhancements does Scope3 provide to sales agents?

On the sales agent side, Scope3 provides:
  • Hosted open-source version for easy onboarding
  • Technical support during integration
  • Connection to the Scope3 buyer ecosystem
The sales agent itself is open source or provided by third-party vendors.

​
Does Scope3 provide signal agents to advertisers?

No, Scope3’s platform connects to signal agents but doesn’t provide them. Publishers build signal agents to expose their unique data and capabilities.

​
Can we add custom targeting adapters (like Weather)?

Yes! If you have proprietary data (weather triggers, custom audiences, etc.), you can build a signal agent that exposes this data to buyer agents. See Signals Agents Integration.

​
How does the signal agent handle dynamic updates?

Signal agents attach data to Scope3 via the Data Attachment API (offline integration). You manage your data through:
  1. Scope3 Data Attachment API - Standard integration for attaching contextual data
  2. Your signal agent - Prepares and sends data to Scope3
  3. Your own systems - Direct database/API updates that feed the signal agent
Scope3 syncs this data to AXE periodically. During real-time bidding, AXE uses the pre-synced data for fast campaign matching.

​
Do we need direct DSP/SSP integrations outside the signal agent?

No! That’s what AXE does. The signal agent exposes your data through a standard interface, and AXE handles the activation into your ad server. No separate DSP/SSP integrations required.

​
Technical Integration

​
What integrations do we need at minimum?

Minimum viable integration:
  1. AXE integration (via Prebid or server-side)
  2. Sales agent connection
  3. GAM/ad server configuration
Recommended additions: 4. Signal agent for your unique data 5. Creative agent for dynamic creative 6. Webhook integration for reporting

​
Do we have to integrate Prebid to use Scope3?

No, but Prebid is the easiest path. Options include:
  • Prebid.js - Client-side integration (easiest)
  • Prebid Server - Server-side prebid
  • Server-to-server - Direct API integration (requires development)

​
What’s required to integrate with ad servers besides GAM?

Scope3 works with any ad server that supports:
  • Key-value targeting (for segments)
  • Macro substitution (for creative personalization)
  • OpenRTB or similar protocols
Supported ad servers include GAM, Springserve, Freewheel, and custom solutions.
