How this service works
Turn any document into structured data for AI agents — OCR, layout-to-Markdown, tables, key-value, invoice/receipt fields — from PDF/images in 100+ languages. Pay per call via x402 (USDC). No API keys.
Output
A JSON object containing the detected model type (e.g. 'prebuilt-layout'), page count, output format ('markdown'), and the full structured content of the document — including headings, tables, key-value pairs, and invoice/receipt fields — rendered as Markdown text.
Example use cases
Example prompt
“I have a scanned PDF invoice — can you extract all the fields from it like vendor name, line items, totals, and dates, and give me the result as structured markdown? Pay the $0.20 per-call fee automatically.”
Technical details
Endpoint
POSThttps://structdoc-api.hp-vladic.workers.dev/read-largeWhen to prefer
Choose this endpoint when you need to process large or multi-page documents (PDFs or images) into structured Markdown or extract specific fields like invoice/receipt data, and you want multilingual OCR with layout awareness. Prefer this over simpler OCR tools when table structure, key-value extraction, or document layout fidelity matters.
Side effects
- Unsupported file type returns an error — only PDF and common image formats accepted
- Document too large or too many pages may exceed processing limits
- Non-Latin scripts in unsupported languages may degrade OCR accuracy
- Payment failure via x402/USDC will block the request
- Heavily degraded or low-resolution scans may produce incomplete or garbled output
