Panel conveyancing API for quoting, instructing and managing conveyancing work through Landmark Optimus. Introducers create quotes, choose a conveyancer and instruct on a client's behalf; conveyancers accept or reject assigned cases and progress them against one shared case record. Twenty paths across Quotes and Cases including quote PDF generation, persons, instruct, accept/reject, status, handler, activities, tasks, notes and documents. Version 0.8.1, OpenAPI 3.0.3, with several endpoints explicitly marked Preview and not yet safe to build against. Uses OData-style $filter and $orderby query parameters, but is not an OData service and publishes no $metadata document.
