Docs: ZeroGPU Real Time Data Module (PBS-Go)

Documentation for a new Prebid Server Go module, zerogpu.rtd, which enriches an incoming OpenRTB request with IAB content categories derived from the publisher's domain.

Code PR: prebid/prebid-server#4906

Changes

• Adds prebid-server/pbs-modules/zerogpu-rtd.md
• Adds a row to prebid-server/pbs-modules/index.md with a check in the PBS-Go column only

What the module does

On each auction it resolves the domain from the bid request, classifies it with ZeroGPU's zlm-v1-iab-domain-classifier model, and appends the resulting categories to {site,app,dooh}.content.data as Seller-Defined contextual segments under ext.segtax: 6 (IAB Content Taxonomy 2.2). Segments therefore reach every bidder through standard First Party Data rather than any bidder-specific mechanism.

The page follows the structure used by the existing module pages: Overview, Prerequisites, Configuration (host and account-level, with the parameter table), how the request is enriched, Privacy, Analytics Tags, Troubleshooting, Support, and Further Reading.

Privacy section

The default configuration sends only a domain and writes only contextual data, so it has no user privacy implications. The page documents the opt-in enrich_user_audience flag prominently, including why it defaults to false: the segments are domain-inferred rather than user-observed, and PBS-Go does not currently expose the enrichUfpd Activity Control to modules, so the module cannot perform that check on the host's behalf.

Checks run

Per AGENTS.md:

• markdownlint --config .markdownlint.json on both changed files — clean, exit 0
• bundle exec jekyll build — builds successfully, no warnings
• Both changed pages render, and all five internal links resolve against the built _site, including the #segments-and-taxonomy anchor on /features/firstPartyData.html

Maintainer contact is the group address prebid@zerogpu.ai.
