## 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 agent-hub-image-describe-ocr-59d9fd7f
```

Example prompt: Can you read all the text on this receipt image and describe what else is in it? Here's the URL: https://example.com/receipt.jpg

## When to prefer this

Choose this endpoint when you need to extract text from images (OCR), understand the visual content of receipts, screenshots, signs, or charts, or answer a specific question about an image — especially when you have a public URL or base64 image and need a pay-per-call solution without an API key or subscription.

## Known failure modes

- Image URL not publicly accessible or returns 4xx/5xx — request fails
- Image exceeds 8 MB size limit — rejected
- Unsupported image format (not jpeg, png, webp, or gif) — rejected
- Both url and image_base64 missing — invalid input
- Heavily blurred or low-resolution image — poor OCR accuracy with incomplete text extraction
- Network timeout fetching remote image URL

## How this service works

Describe an image and read every piece of visible text in it (vision LLM). Send a public image URL or base64 image; optional custom question. Works for receipts, screenshots, signs and charts. Also callable as GET with the same fields as query parameters.

## Output

Returns a natural-language description of the image's visual content along with all visible text extracted via OCR, optionally answering a custom question about the image. Output includes the full textual content found in the image and a descriptive summary of what is depicted.
