# List immutable homology semantic and ranking contracts

> Returns one cursor page of the semantic profiles releases can select. A profile fixes the scientific meaning of a search — the embedding contract results are comparable within, the ranked unit, the ordered comparators, and the tie-breaker — and deliberately exposes no retrieval or execution settings.
