## 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 fastapi-online-ocr-image-text-extraction-56bd6c17 -d '<json body>'
```

Example prompt: Can you extract all the text from this image of a receipt I just uploaded — it's a JPEG photo of a printed receipt and I need the text contents pulled out?

## When to prefer this

Choose this endpoint when you need a pay-per-call OCR service with no account signup, paying in USDC crypto via x402. It is well-suited for agents that process images on demand without committing to a subscription, and when you need structured line-level output alongside raw text. Prefer it over cloud OCR services when anonymity, crypto payment, or avoiding API key management is a priority.

## Known failure modes

- Unsupported file format (non-PNG/JPEG/WebP) results in error
- Low-quality or blurry images may yield incomplete or garbled text
- Handwritten text may have reduced accuracy depending on the OCR engine
- Payment failure or insufficient USDC balance returns 402 status
- Missing required 'file' field returns 422 validation error
- Very large image files may time out or be rejected
