## 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 prepared-image-ocr-four-languages-english-french-german-spanish-f7556ad0 -d '<json body>'
```

Example prompt: Can you extract the printed text from this PNG image? It's a scanned French document — please run OCR on it and tell me what it says along with how confident you are.

## When to prefer this

Choose this endpoint when you need lightweight, low-cost OCR ($0.01 per call) on a single PNG image containing printed text in English, French, German, or Spanish. It is ideal when you want both the extracted text and a preprocessed image returned together, and when local Tesseract accuracy is acceptable. Prefer it over heavier cloud OCR APIs when privacy, cost-efficiency, or simplicity matter and the document is clean printed text rather than handwriting.

## Known failure modes

- Image exceeds 600 KB or 4 million pixels — request rejected
- Non-PNG image format submitted — may fail or produce garbled output
- Handwritten text not reliably recognized — low confidence score returned
- Unsupported language code provided — defaults to English or returns error
- Heavily degraded or very low-resolution image — low confidence or empty text output
- Base64 encoding is malformed — request fails with parse error

## How this service works

Prepared Image OCR: Four Languages: Grayscale and contrast-normalise one PNG, then read printed English, French, German or Spanish text with local Tesseract. Up to 600 KB and four million pixels. Returns text, confidence and the prepared image; handwriting and accuracy are not guaranteed. 0.01 USDC includes one bounded document-data report.

## Output

Returns the OCR-extracted text from the printed content in the image, a confidence score indicating OCR reliability, and the preprocessed (grayscale, contrast-normalized) version of the input PNG. Handwriting recognition and pixel-perfect accuracy are not guaranteed.
