Supply one element per underwriting **agency** line (one for the main Agency line; an additional one for the Mosaic Asta Europe agency line when the risk has an EEA component). **Front end supplies agency-line data only.** Trident retrieves all XFI-created lines (agency + syndicate) via *Get All Lines*, identifies each by Division ID (Agency = front-end `division.id`; MAE = 7; 1609 = 3; 2610 = 12; 5399 = 6; 5431 = 13), and propagates most agency-line values to the syndicate lines ("Same as Agency Line"). Derived-only fields (`originatingDivision`, `originatingOffice`, global-risk cross-reference, inclusive-line) are computed by Trident and are **not** part of this payload. Fields are grouped by stage: Submission → Quote → FON → Bind. ## OpenAPI definition ```yaml openapi: 3.0.1 info: title: Trident APIs version: uat servers: - url: https://apinonprod.mosaicinsurance.com description: Generated server url components: schemas: IdReference: type: object description: Reference to a lookup-backed entity identified by `id` (the XFI lookup id, environment-specific). required: - id additionalProperties: false properties: id: type: string description: XFI lookup id — the canonical identifier (environment-specific). example: "260" Line: type: object description: >- A single **agency** policy line within a quote submission.
