## 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 relaystation-image-ocr-e6d08b15 -d '<json body>'
```

Example prompt: Can you extract all the text from this image of my receipt? It's in English — just give me the plain text.

## When to prefer this

Choose this endpoint when you need fast, low-cost OCR on a single image and plain text output is sufficient. It is ideal for agent pipelines that need to digitize receipts, screenshots, scanned documents, or image-embedded text without requiring structured data extraction. Prefer it over vision-LLM approaches when cost per call matters and Tesseract accuracy is adequate for the language and image quality.

## Known failure modes

- Image URL is inaccessible or returns a non-image response — endpoint returns an error
- Image format is unsupported — only common raster formats (JPEG, PNG, etc.) are handled
- Low image quality or resolution results in garbled or incomplete text extraction
- Language not in supported set of 10 — may produce poor results
- Payment insufficient — x402 minimum charge is 1¢ USDC

## How this service works

$0.003/call. Extract text from an image — Tesseract, 10 languages, plain text out. 1¢ x402 min; remainder auto-credits — relaystation.ai/penny

## Output

Plain text string containing all text recognized in the image, extracted via Tesseract OCR across up to 10 supported languages
