How this service works
PDF or picture in, structured JSON out, with a page and a position behind every field, plus every QR code and barcode decoded. Paid per page in USDC over x402. No signup, no API key.
Output
Returns a structured JSON object containing extracted text blocks, tables, layout metadata, and decoded QR/barcode values — each annotated with the page number and bounding-box position of the field within the original document. Output sections depend on the 'want' parameter (text, tables, codes, layout).
Example use cases
Invoice data extraction for accounting
“I have a scanned invoice PDF at https://example.com/invoices/march2024.pdf — can you pull out all the text and tables as structured JSON, including positions, and also decode any barcodes on it? Just pages 1 and 2.”
Form digitization from a photo
“I took a photo of a filled-out registration form — here it is as a base64 image, JPEG format. Can you OCR it and give me back all the fields as structured JSON with their positions on the page? It's in German and English.”
QR code and barcode decoding from document
“There's a product sheet PDF at https://example.com/product_sheet.pdf — can you scan it for all QR codes and barcodes and tell me what they decode to, along with where on each page they appear?”
Technical details
Endpoint
POSThttps://doc.netzhandwerker.de/ocr?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need structured JSON output from PDFs or images with precise page and position metadata per field, or when you need barcode/QR decoding alongside text and table extraction. It requires no API key or signup and charges per page in USDC via x402, making it ideal for serverless or agent workflows needing anonymous, pay-as-you-go document parsing. Choose alternatives if you need languages beyond German and English, more than 50 pages per call, or non-x402 payment methods.
Side effects
- MIME type mismatch between declared 'mime' and actual file bytes — request refused
- Both 'url' and 'image_base64' provided simultaneously — request rejected
- Page range exceeds 50-page limit — error returned
- Unsupported language outside installed models (deu, eng) — error returned
- Payment failure via x402 — request not processed
- URL unreachable or returns non-200 — extraction fails
- Corrupted or password-protected PDF — extraction fails or returns partial results

| Field | Type | Description |
|---|---|---|
| url | string | Public http or https URL of the picture or PDF. Use this or "image_base64", not both. |
| mime | string | Media type of the input. Checked against the actual bytes; a mismatch is refused rather than worked around. |
| want | array | Which parts of the answer to compute. The price does not change with it; asking for less is simply faster. |

| languages | array | Languages to read, default deu plus eng. Installed models: deu, eng. |
