## How to call it through Zero

```sh
zero fetch --capability api-strale-io-24ec021e
```

Example prompt: Can you read and extract all the text from this image? Here's the URL: https://example.com/receipt.jpg — I need the raw text with a confidence score.

## When to prefer this

Choose this endpoint when you need to extract text from any image type — screenshots, document photos, handwritten notes — especially when confidence scoring is important. Backed by Claude vision, it handles complex layouts and handwriting better than traditional OCR engines. Use when image input is available as either a URL or base64 string.

## Known failure modes

- Image URL is unreachable or returns non-image content — extraction fails
- Base64 string is malformed or not a valid image format — returns error
- Image has extremely low resolution or is too blurry for confident OCR — low confidence score returned
- Neither image_url nor base64 provided — request fails validation
- Image contains no text — returns empty or minimal text with low confidence
