Reach for it to populate a tax-code picker or to resolve the rate a product's `taxCode` points at. Each `rateBps` is the rate in BASIS POINTS of a percentage (20% → 2000, 5.5% → 550), so divide by 100 to render a percentage. Filter with `active` (`"true"`/`"false"`) and/or `country` (ISO alpha-2); sort by `code`, `label` or `rateBps`; page with `page`/`pageSize` (max 100) until `page` reaches `pageCount`. ## OpenAPI ````yaml /openapi.json get /v1/tax-codes openapi: 3.0.3 info: title: Solya POS API version: 1.0.0 description: >- The Solya POS backend HTTP surface.
