Scope3 RTD Module
Scope3 implements the AdCP AXE (Agentic eXecution Engine) protocol to augment agentic decisions with real-time access to high-cardinality data. This guide covers technical integration with Scope3’s RTD module for various ad server combinations.Overview
Scope3’s AXE implementation expects an OpenRTB-compatible request and returns a list of segments for inclusion, exclusion, and macros. These segments should be passed into the ad server for targeting. This integration can happen client-side (via Prebid.js), server-side (via Prebid Server), or through a custom real-time data provider integration (typically for SSPs or ad networks). Custom integrations require development work - contact Scope3 to discuss technical requirements.Data Flow
How AXE Works
Component Roles
Campaign Setup (Offline): Buyer Agent (DSP-like):- Creates campaigns in Scope3
- Defines targeting criteria
- Sets budgets and goals
- Maps campaigns to segments (axei)
- Receives signal data via Data Attachment API
- Syncs campaign + signal data to AXE
- Pushes campaigns to sales agents
- Attach contextual data to Scope3 via Data Attachment API
- Weather, audience, inventory attributes
- Custom publisher capabilities
- Receives campaign from Scope3
- Creates line item in ad server
- Configures line item to target axei segment
- Uploads creative with axem macro
- Stores line items targeting axei segments
- Holds creatives with axem macros
Real-time Ad Serving: Ad Server:
- Initiates ad request to Prebid
- Sends OpenRTB bid request to AXE
- Receives segments from AXE
- Passes key-values back to ad server
- Receives OpenRTB requests from Prebid
- Uses pre-synced campaign and signal data
- Matches campaigns to impressions
- Returns segments (axei, axex, axem values)
- Matches line items targeting axei segment
- Selects winning creative
- If Scope3 creative wins: Substitutes axem macro
- Delivers ad to user
Segment Types
| Segment Key | Purpose | Example |
|---|---|---|
axei | Inclusion targeting | Audience match for campaign |
axex | Exclusion/safety | Brand safety blocks |
axem | Creative macros | Personalization values |
Decide on AXE Key Names
Scope3 will use these default key names:axei- Inclusion segments (1P audience matching)axex- Exclusion segments (brand safety blocks)axem- Creative macros
Prebid.js Implementation
Install Scope3 RTD Module in Prebid
Scope3’s RTD provider module was added to Prebid in version 10.9.0. The module was also added to a fork of Prebid 9.x. If building Prebid.js from source, include the Scope3 RTD module:Configuration
Add the Scope3 RTD provider to your Prebid configuration using this config snippet:Prebid Server Implementation
Add the Scope3 Prebid Server module to your Prebid Server setup and add the config snippet to your configuration file. (Scope3 todo: add a full example here)Server-to-server Implementation
See Scope3 RTD DocumentationTesting and Validation
For testing purposes, Scope3 will send a test segment until live segments are available (should betest-dnu or something similar)
Check that AXE Segments are flowing into Prebid
- Open your browser’s developer tools
- Navigate to a page with ads
- Look for Scope3 RTD activity in the console
- Verify segments are being passed through Prebid into the ad server
