External Contextual Data Provider: Mixpeek Server-Side RTD Reference

[esteininger]

Hey everyone 👋

We've open-sourced a reference implementation for server-side contextual enrichment that works alongside Prebid Server.

What It Is

This is an external data provider (not a native Go module) that enriches OpenRTB bid requests with contextual signals before they hit your PBS auction.

Type	Description
Reference Implementation	OpenRTB enrichment logic
Test Harness	Validate bid request enrichment locally
Node Gateway Utility	For teams with Node proxies in front of PBS

Why We Built It

• Cookie deprecation is here
• • SSPs need contextual signals that work server-side
• • Wanted something that doesn't require modifying PBS core

What It Provides

• IAB v3.0 taxonomy classification
• • Brand safety scoring
• • Keyword extraction
• • Sub-100ms latency with caching
• • Graceful degradation (never blocks auctions)

OpenRTB 2.6 Output

Enriches standard fields:

• ortb2.site.content.cat - IAB categories
• • ortb2.site.content.keywords - Keywords
• • ortb2Imp.ext.data.hb_mixpeek_* - Targeting keys
