The current response has no separate task-status field. While processing is still in progress, the service may return `code=success` with an empty `img_detail_list` and zero `total_num`. Poll with backoff and stop only after page results or a spreadsheet structure is available. An empty result cannot reliably distinguish "still processing" from "no visual pages." Set a total client timeout and a maximum poll count. ## OpenAPI ````yaml en/api-reference/adp-api.yaml GET /open/agentic_doc_processor/{tenant_name}/v1/doc/convert/query/task/{task_id} openapi: 3.1.0 info: title: ADP API version: 1.0.0 description: >- Laiye ADP OpenAPI reference for document extraction, recognition, and conversion; extraction application management; webhooks; human collaboration; credit usage; workflow discovery, runs, exports, and file management. license: name: MIT identifier: MIT servers: - url: https://adp-global.laiye.com description: ADP global production endpoint security: [] tags: - name: Document extraction description: Extract structured fields from uploaded documents. - name: Document recognition description: Recognize text, layout blocks, and positions from uploaded documents. - name: Document conversion description: >- Convert PDFs, Office documents, OFD files, and images into page images or native spreadsheet structures. - name: Application management description: >- Create, update, delete, and query extraction applications and configurations. - name: Webhook description: List system events and manage event callbacks. - name: Account description: Query credit usage. - name: Workflow description: >- List business workflow templates, run workflow applications, and query run results. - name: Workflow files description: Upload and manage files used by workflow applications. - name: Human collaboration description: >- Configure review triggers, query collaboration tasks, and submit human corrections. paths: /open/agentic_doc_processor/{tenant_name}/v1/doc/convert/query/task/{task_id}: get: tags: - Document conversion summary: Query asynchronous document conversion task description: > Query a conversion result by `task_id`.
