# Get Catalog Valuations

Source: https://recoupable.dev/docs/api-reference/songs/catalog-valuations

Get the persisted valuation history for a catalog, latest first. A row is written each time a valuation band is computed for the whole catalog (valuation runs and measurement reads persist at most one row per catalog per day). Use limit=1 for the current value. History is what makes week-over-week deltas possible.
