Exoa Data Extraction API Development

Extract, chunk, and structure content from PDFs, Office docs, images, audio, and 60+ formats — ready for RAG, fine-tuning, or any LLM workflow.

[01] How it works

Upload any file, Exoa extracts and chunks the content, and you get clean JSON or Markdown back.

Send any file via our REST API or drag-and-drop in the dashboard. Exoa handles 60+ formats including PDFs, Office documents, images with OCR, audio transcription, and more.

Exoa extracts text, tables, and images, then chunks content using semantic or fixed-size strategies with accurate GPT-4 token counts for each chunk.

Receive clean JSON or Markdown with every chunk, token count, page reference, and element type — ready to feed directly into your RAG pipeline or LLM context window.

[02] Platform

Everything you need to turn raw files into structured, LLM-ready data with a single API call.

One API handles PDFs, Office docs, images, audio, email, ebooks, markup, and legacy formats. No more juggling different libraries for each file type.

Split documents by structure with semantic chunking or by size with fixed chunking. Each chunk includes accurate GPT-4 token counts and page references.

Use the REST API for automation or the web dashboard for drag-and-drop uploads. Both return the same structured output in JSON or Markdown.

Tables are preserved as structured data with HTML representation. Images get AI-generated descriptions via BLIP, with optional base64 inclusion.

[03] Security

Your files are processed locally on our infrastructure — no data is sent to third-party APIs. Secure authentication and encrypted transport keep your content safe.

Your files never leave our infrastructure. OCR, transcription, and extraction all happen locally — no data is sent to external services.

API keys with per-minute and per-day rate limits for programmatic access. Session-based auth with httponly cookies for the dashboard.

All API traffic is served over HTTPS. API call logging tracks usage, response times, and errors for monitoring.

[Why It Matters]

The knowledge your AI needs is trapped inside files — PDFs, spreadsheets, scanned documents, audio recordings. Getting it out means writing custom parsers for every format.

Exoa handles the extraction so you can focus on building.

Replace brittle extraction scripts with a single API call that handles OCR, table parsing, and chunking automatically.

Exoa replaces your file parsing stack with a single API so you can ship AI features, not maintain extraction pipelines.

[04] Use cases

Common workflows where Exoa saves you from writing custom extraction code.

Get pre-chunked, tokenized content with page references and element types — ready to load directly into your vector store for retrieval-augmented generation.

Convert contracts, reports, manuals, and filings into structured JSON that fits cleanly into LLM context windows with accurate token counts.

Extract tables, text, and metadata from PDFs, scanned documents, and Office files. Get structured data without writing format-specific parsers.

Transcribe audio files via Whisper and extract text from images via OCR — all through the same API, with the same structured output format.

[05] Supported formats

One API endpoint handles all of these. Upload any supported file and get structured output back.
