The coordinate for the surface where AI answers cite their sources.

An exact-match position for the citation layer — the place where retrieval and generative systems attribute the sources behind an answer.

Coordinated sets this position belongs to — the coverage it extends. Counts are the live cluster size in the graph.

Why this is canonical

As AI search and RAG systems mature, the citation surface — the set of sources an answer points back to — has become a first-class object that brands, publishers, and tools now compete to appear on. Naming that surface plainly on the default commercial TLD lands the attribution coordinate of the agentic web at the exact layer this discipline is forming around.

Where it fits

Two genuinely distinct surfaces sit under this coordinate —

Retrieval / generative-answer citation
The surface where AI search and RAG systems expose and attribute their sources; visibility and monitoring for what gets cited.
AI-search visibility, GEO, and RAG-tooling builders
Academic / legal citation
The structured surface for scholarly and legal references — citation graphs, weighting, and verification.
Research-tooling, legal-tech, and scholarly-graph teams

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own build.
