## 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 ocr-text-extraction-api-klymax402-53d9ef0d
```

Example prompt: Can you extract all the text from this image — https://example.com/menu-photo.jpg — using English as the language hint?

## When to prefer this

Use this endpoint when you need to extract text from an image file or URL, especially when you have a language hint to improve accuracy. Suitable for receipts, screenshots, scanned documents, signs, and labels. Prefer over general vision APIs when cost-per-call predictability and x402 micropayment compatibility are required.

## Known failure modes

- Image URL is unreachable or returns a non-image response — OCR fails or returns empty result
- Base64 data is malformed or corrupt — decoding error returned
- Unsupported image format — extraction may fail or return garbage text
- Language hint is invalid or unsupported — may fall back to default English or return an error
- Image contains no readable text — returns empty or near-empty result
- Payment not included or insufficient — 402 Payment Required response
