How this service works
Reads an image's text and word boxes (Tesseract txt, TSV, hOCR and ALTO).
Output
Returns OCR results for the submitted image in the requested format: plain text string (text), tab-separated values with confidence and bounding box columns (tsv), hOCR HTML with spatial metadata (hocr), ALTO XML (alto), or a structured list of word objects with coordinates (words).
Example use cases
Digitize scanned document text
“I have a scanned page from a contract as a PNG — can you extract all the readable text from it and give me the plain text output?”
Extract word boxes for document layout analysis
“Take this PNG screenshot of a form and give me the word-level bounding boxes in hOCR format so I can figure out where each field label appears on the page.”
Parse receipt or invoice image
“Here's a photo of a receipt encoded in base64 — run OCR on it and return the results as TSV so I can pull out the line items and prices programmatically.”

Endpoint
POSThttps://lensaocr.saastemly.com/v1/ocr?utm_source=zero.xyzWhen to prefer
Choose LensaOCR when you need Tesseract-backed OCR with multiple structured output formats (especially TSV or hOCR with bounding boxes) and want a pay-per-call API without managing Tesseract infrastructure. Ideal for document processing pipelines, form digitization, and layout-aware text extraction where word-level spatial data matters.
Side effects
- Image exceeds 5 MB limit — request rejected
- Image not valid PNG or improperly base64-encoded — decode error
- Low-quality or blurry image — Tesseract returns empty or garbled text with low confidence
- Unsupported format enum value — validation error
- Non-Latin or unsupported script — Tesseract may return poor results depending on language model
