9 Listing Types Explained
Every listing on Zetto has a card type that determines two things: its direction (offering or seeking) and which types it matches with. The matching engine uses type complementarity as its first filter — a selling listing will only match with buying, never with another selling.

How type matching works
Section titled “How type matching works”Type complementarity is the first layer of the 3-layer matching engine:
- Structural pre-filter — Only complementary types pass (e.g.,
sellingcan only matchbuying). This runs in under 10ms using a SQL RPC. - Embedding rerank — Cosine similarity scores from vector embeddings refine the results.
- AI refinement (optional) — An AI model reranks the top candidates for relevance.
