# Citiview Image Describe & OCR (Vision LLM)

> Citiview Image Describe & OCR (Vision LLM) is a paid API for AI agents from agents.citiviewgroup.com, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-14).

Analyzes a public image URL or base64-encoded image using a vision LLM to describe its contents and extract all visible text, with optional custom questions.

## 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 citiview-image-describe-ocr-vision-llm-7d965f79
```

Example prompt: Can you read all the text and describe everything you see in this receipt image? Here's the URL: https://example.com/receipt.jpg

## When to prefer this

Choose this endpoint when you need to extract text (OCR) from images, describe visual content, or answer specific questions about an image — especially for receipts, screenshots, signs, charts, or documents. It is ideal when the image is already hosted at a public URL or available as base64, and you need both visual description and text extraction in a single call. Prefer this over dedicated OCR tools when you also need semantic understanding of the image content, not just raw text.

## Known failure modes

- Image URL is not publicly accessible or returns 404 — no content can be fetched
- Image exceeds 8 MB size limit — request rejected
- Unsupported image format (not jpeg, png, webp, or gif) — processing fails
- Base64 string is malformed or corrupted — decoding error
- Image contains no readable text — description returned but OCR yields empty result
- Network timeout fetching remote image URL — transient failure
- Payment of 0.01 USDC not received — 402 response, endpoint not called

## 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

A natural language description of the image contents along with all visible text extracted from the image. If a custom prompt/question was provided, the response also includes a direct answer to that question based on what the vision LLM sees in the image.
