When you pass the app_id of a high-speed custom extraction application, the high-speed auto-configuration service returns a configuration preview such as common_rule, field_rule, and table_rule. This endpoint does not save a configuration version or automatically populate the Web application. High-speed applications must provide file_url or file_base64. prompt is only used as an auxiliary instruction. ## OpenAPI ````yaml /en/api-reference/adp-api.yaml post /open/agentic_doc_processor/{tenant_name}/v1/app-manage/ai-recommend openapi: 3.1.0 info: title: ADP API version: 1.0.0 description: >- Laiye ADP OpenAPI reference for document extraction, document recognition, application management, credit usage, workflow runs, and workflow 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: Application management description: >- Create, update, delete, and query extraction applications and configurations. - name: Account description: Query credit usage. - name: Workflow description: Run workflow applications and query run results. - name: Workflow files description: Upload and manage files used by workflow applications. paths: /open/agentic_doc_processor/{tenant_name}/v1/app-manage/ai-recommend: post: tags: - Application management summary: Generate extraction field prompts description: >- Generate field names, field types, field prompts, and other configuration references from a sample document or prompt.
