You can download the source document to follow along: Insurance Policy PDF The screenshot below shows the first page of the document. First page of a homeowner's insurance policy {section} analyzed the full document and returned a hierarchical table of contents. The **Declarations And Policy Overview** section on the first page appears as section `2` (level 1) in the response. **Insured Property** and **Policy Period And Renewal** are its level 2 subsections, each with their own level 3 sub-subsections. Each entry's `start_reference` points to the chunk where that section begins in the parsed document. ```json [expandable] theme={null} { "table_of_contents": [ { "title": "Policy Header", "level": 1, "section_number": "1", "start_reference": "1c4b7184-346d-490f-a7bf-bf2442bcbd7c" }, { "title": "Declarations And Policy Overview", "level": 1, "section_number": "2", "start_reference": "494d766e-5cf1-48c4-a580-73061b722b90" }, { "title": "Insured Property", "level": 2, "section_number": "2.1", "start_reference": "1e6c9100-f461-4bb8-8dcd-8ae0311a97c0" }, { "title": "Mortgage And Lienholder", "level": 3, "section_number": "2.1.1", "start_reference": "95e79ad7-72b5-4c9f-9717-8488996c6795" }, { "title": "Detached Structures", "level": 3, "section_number": "2.1.2", "start_reference": "4c1e087b-aee9-4494-9789-735388a7579c" }, { "title": "Policy Period And Renewal", "level": 2, "section_number": "2.2", "start_reference": "de55b7d5-df5c-480e-8b91-0f9f10f5b059" }, { "title": "Cancellation", "level": 3, "section_number": "2.2.1", "start_reference": "7cc48544-b2ec-4e34-b2a1-ae1b3b7d17a6" }, { "title": "Annual Premium", "level": 3, "section_number": "2.2.2", "start_reference": "b8c0ba71-d786-4f89-a07f-3fcfc0edd734" }, { "title": "Schedule Of Coverages And Limits", "level": 1, "section_number": "3", "start_reference": "3700c26c-dd67-4dda-a712-081becb9ab63" }, { "title": "Coverage A Dwelling", "level": 2, "section_number": "3.1", "start_reference": "de789af4-1585-4b3f-9193-4253a9e58f6b" }, { "title": "Ordinance Or Law", "level": 3, "section_number": "3.1.1", "start_reference": "c7eaad71-19ca-4ab4-90cb-e8e9581ededc" }, { "title": "Named Storm Deductible", "level": 3, "section_number": "3.1.2", "start_reference": "d1300436-0131-49d1-a98a-1f46ece31c23" }, { "title": "Coverage C Personal Property", "level": 2, "section_number": "3.2", "start_reference": "80ed234f-1824-4def-b7fb-6883c3fa2b52" }, { "title": "Sub Limits", "level": 3, "section_number": "3.2.1", "start_reference": "0c3e0c5a-80ee-49f6-9ca5-52941547d4bd" }, { "title": "Business Property", "level": 3, "section_number": "3.2.2", "start_reference": "60aba72b-ca56-4806-97b0-bdf580669943" }, { "title": "Exclusions", "level": 1, "section_number": "4", "start_reference": "29529f14-e489-4f2a-bea8-0eef68f431b0" }, { "title": "Earth Movement And Flood", "level": 2, "section_number": "4.1", "start_reference": "51c3a6b7-7b78-404e-a1f3-b39be8498294" }, { "title": "Ensuing Loss", "level": 3, "section_number": "4.1.1", "start_reference": "908cf899-f5af-40c8-9829-4e09da9083c9" }, { "title": "Concurrent Causation", "level": 3, "section_number": "4.1.2", "start_reference": "f48d2861-3d9a-4db6-b2d1-78d22013c3fb" }, { "title": "Other Exclusions", "level": 2, "section_number": "4.2", "start_reference": "3336ee6d-9723-4fe1-914f-75109187cc0a" }, { "title": "Wear And Tear", "level": 3, "section_number": "4.2.1", "start_reference": "f66ab1c5-d5fe-42ac-bf71-56a3c769a0a6" }, { "title": "Vacancy", "level": 3, "section_number": "4.2.2", "start_reference": "75eff73f-3166-45dd-9140-a9182f858e47" }, { "title": "Claims And Conditions", "level": 1, "section_number": "5", "start_reference": "35ccfa20-00fb-462e-b375-aaa1b84a1d8f" }, { "title": "Duties After A Loss", "level": 2, "section_number": "5.1", "start_reference": "a08d6602-32b0-41e0-ad85-5d951dfc93c0" }, { "title": "Notice Deadline", "level": 3, "section_number": "5.1.1", "start_reference": "a68996f1-acd7-403e-bb68-58a7fbe336f0" }, { "title": "Emergency Repairs", "level": 3, "section_number": "5.1.2", "start_reference": "edd78fe8-08d6-4f55-a19b-d15a2a05464b" }, { "title": "Dispute Resolution", "level": 2, "section_number": "5.2", "start_reference": "bdf63da4-4f34-48f0-82a2-cece1ef666d0" }, { "title": "Suit Limitation", "level": 3, "section_number": "5.2.1", "start_reference": "db860fc2-e02e-4efa-8205-553b392b63ca" }, { "title": "Loss Payment", "level": 3, "section_number": "5.2.2", "start_reference": "0f7081fd-75c2-4e0f-8355-b4d66a13c20f" }, { "title": "Policyholder Acknowledgment", "level": 1, "section_number": "6", "start_reference": "065d0342-0c5b-4fbc-9888-b78ac5e0fefc" }, { "title": "Signature Lines", "level": 1, "section_number": "7", "start_reference": "f47e4117-eda0-477d-9a76-482bff511444" } ], "table_of_contents_md": "- [Policy Header](#1c4b7184-346d-490f-a7bf-bf2442bcbd7c)\n- [Declarations And Policy Overview](#494d766e-5cf1-48c4-a580-73061b722b90)\n -

The flat list structure is optimized for retrieval use cases. You can iterate the list directly without recursion. Each entry includes: | Field | Description | | ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `title` | The generated text for the section heading. | | `level` | The hierarchy depth. Top-level sections are `1`, subsections are `2`, sub-subsections are `3`, and so on. | | `section_number` | The hierarchical number for this section (for example, `"1"`, `"1.2"`, `"1.2.3"`). Use this field to reconstruct parent-child relationships: entry `"2.1"` is a child of entry `"2"`. | | `start_reference` | The ID of the chunk where this section begins. This corresponds to a `chunks[].id` value from the [{parse} API](https://docs.landing.ai/api-reference/tools/ade-parse) response. | ## Markdown Table of Contents (`table_of_contents_md`) The `table_of_contents_md` field provides a ready-to-use Markdown-formatted TOC. Each entry is an anchor link pointing to the corresponding [reference anchor](./ade-markdown-response#anchor-tags) in the document Markdown. Indentation represents the hierarchy level. You can prepend this string to the document's full Markdown to enable in-document navigation: ```text theme={null} - [Introduction](#uuid_a1) - [Methods](#uuid_b2) - [Data Collection](#uuid_c3) - [Survey Design](#uuid_d4) ``` ## Processing Metadata (`metadata`) The `metadata` field provides information about the sectioning process: | Field | Description | | -------------- | -------------------------------------------------------------------------------------------------------------- | | `filename` | The name of the input Markdown file. | | `org_id` | Organization identifier. | | `duration_ms` | Processing time in milliseconds. | | `credit_usage` | Number of credits consumed. | | `job_id` | Unique job identifier. | | `version` | Model version used for sectioning. For more information, go to [Section Model Versions](./ade-section-models). |
