# Document Extraction APIs — buyer checklist (RFP) Derived from ProductArena's evidence-graded user-story taxonomy for Document Extraction APIs: 53 judged requirements. Priorities mirror story weights (3 = must-have, 2 = should-have, 1 = nice-to-have). ## Agenticness - [ ] **[must-have]** Plug MCP servers into this product so it can use their tools - [ ] **[must-have]** Connect an agent via an official MCP server - [ ] **[must-have]** Drive the product through a documented public API - [ ] **[must-have]** Delegate tasks to a built-in AI assistant inside the product - [ ] **[should-have]** Point an agent at llms.txt or agent-oriented docs - [ ] **[should-have]** Run the product headlessly / in CI for automation - [ ] **[should-have]** Use an official CLI - [ ] **[should-have]** Issue scoped/least-privilege API credentials for an agent - [ ] **[should-have]** Build against official SDKs - [ ] **[should-have]** Subscribe to events via webhooks - [ ] **[should-have]** Get AI-generated insights and suggestions from my data inside the product - [ ] **[should-have]** Set up automations that run autonomously in the background - [ ] **[should-have]** Operate the product with natural-language commands - [ ] **[should-have]** Explore an interactive API reference with runnable examples - [ ] **[should-have]** Download a machine-readable API spec (OpenAPI or equivalent) - [ ] **[should-have]** Rely on versioned APIs with a documented deprecation policy - [ ] **[nice-to-have]** Test against a sandbox environment without touching production data ## Automation depth - [ ] **[must-have]** Define rules that trigger actions automatically on events - [ ] **[should-have]** Perform bulk operations across many items at once - [ ] **[should-have]** Schedule recurring jobs or workflows - [ ] **[nice-to-have]** Version, review, and roll back my automations ## Deployment compliance - [ ] **[must-have]** Uploaded documents get zero-retention handling with SOC 2 and HIPAA options, so I can process contracts and medical records - [ ] **[should-have]** Run the extraction stack in my own VPC or fully self-hosted when documents can't leave my infrastructure ## Format coverage - [ ] **[should-have]** One API handles my whole document mix — PDF, DOCX, PPTX, XLSX, HTML, images, email — without per-format plumbing - [ ] **[should-have]** Thousand-page documents and multi-gigabyte files process reliably without timeouts or silent truncation ## Ocr multilingual - [ ] **[must-have]** Scanned and photographed documents OCR accurately — skewed pages, stamps, low quality scans included - [ ] **[should-have]** Non-English documents — including CJK and right-to-left scripts — parse with the same fidelity as English - [ ] **[nice-to-have]** Handwritten fields and annotations are recognized and extracted, flagged with confidence when uncertain ## Openness - [ ] **[must-have]** Export all of my data in open formats and leave - [ ] **[must-have]** Self-host the core product - [ ] **[should-have]** Do everything through the API that I can do in the UI - [ ] **[should-have]** Read the product's source under an open license ## Parse accuracy - [ ] **[must-have]** The API parses complex real-world PDFs — multi-column layouts, headers, footers, footnotes — into clean, correctly ordered content - [ ] **[should-have]** Figures and charts are extracted or described (VLM summaries, image crops) with positions traceable back to the source page - [ ] **[should-have]** Parsed output preserves document hierarchy — headings, sections, reading order — so downstream LLMs see structure, not soup - [ ] **[nice-to-have]** The vendor publishes reproducible accuracy benchmarks and I can run my own evals before committing ## Privacy posture - [ ] **[must-have]** Prevent my data from being used to train AI models - [ ] **[should-have]** Choose where my data is stored (region/residency) - [ ] **[should-have]** Control data retention and deletion - [ ] **[should-have]** Opt out of telemetry and usage tracking ## Rag chunking - [ ] **[must-have]** Output comes pre-chunked for RAG — semantic boundaries, metadata, embedding-ready segments — not a wall of text - [ ] **[should-have]** I get clean markdown/JSON designed for LLM consumption, with noise like repeated headers and page furniture stripped ## Scale async - [ ] **[must-have]** Long parses run as async jobs with status polling and completion webhooks, so my pipeline never blocks - [ ] **[should-have]** A fast synchronous mode returns results in seconds for interactive apps, with latency documented per mode - [ ] **[should-have]** I push high-volume batches — millions of pages — with documented rate limits and predictable throughput ## Sdk dx - [ ] **[must-have]** Official typed SDKs for Python and TypeScript cover the full API — parse, extract, jobs — with sensible defaults - [ ] **[nice-to-have]** I drag a document into a web playground and see parse/extract results before writing any code ## Structured extraction - [ ] **[must-have]** I supply a JSON schema and get back validated structured fields extracted from the document - [ ] **[should-have]** Every extracted field carries provenance — page number, bounding box, source snippet — so agents can cite and humans can verify - [ ] **[should-have]** Extractions carry calibrated confidence scores with a human-in-the-loop review path for low-confidence fields - [ ] **[should-have]** Multi-document packets are classified and split automatically — one upload, per-document results ## Table extraction - [ ] **[must-have]** Complex tables — merged cells, nested headers, multi-page spans — come out as faithful HTML/markdown structure - [ ] **[should-have]** I turn extracted tables into typed rows/JSON I can load into a database without manual cleanup --- Source: https://ultrametric.ai/productarena/arena/document-extraction (evidence-graded verdicts for 6 products) · methodology: https://ultrametric.ai/productarena/methodology
