> LensaOCR is a paid API for AI agents from lensaocr.saastemly.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-16).

Extracts text and word bounding boxes from a PNG image using Tesseract, returning results in text, TSV, hOCR, ALTO, or words format.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability lensaocr-35d70fe8 -d '<json body>'
```

Example prompt: Can you read all the text out of this image for me and give me back the word positions too — return it in TSV format so I can work with the coordinates?

## When to prefer this

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.

## Known failure modes

- 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

## 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).
