## 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 the-stall-vision-analyze-ai-image-analysis-via-x402-3588e132
```

Example prompt: Look at this product screenshot for me — https://example.com/screenshot.png — and tell me what UI elements are on the page; use high detail mode.

## When to prefer this

Use this endpoint when you need to understand, extract, or answer questions about the content of a publicly accessible image — especially when you want zero-setup API-key-free access paid per-call in USDC. Choose mode=ocr for text extraction, mode=chart for data/graph images, mode=ui for interface screenshots, mode=qa for targeted factual questions, and mode=describe for general scene understanding.

## Known failure modes

- Image URL is not publicly accessible or returns a non-image content-type — returns an error indicating invalid or inaccessible image
- Image exceeds 20MB file size limit — returns file-too-large error
- mode=qa used without a 'question' parameter — returns parameter validation error
- Image content violates content policy — returns moderation refusal
- Network timeout fetching the remote image URL — returns fetch error

## How this service works

Analyze any image URL using GPT-4o-mini vision. Returns structured analysis based on the mode: describe (full description), ocr (text extraction), chart (data/trend extraction), ui (interface analysis), identify (object/subject ID), or qa (answer a specific question about the image). Input must be a publicly accessible image URL (JPEG, PNG, GIF, WebP). $0.050/call.

## Output

Returns an AI-generated analysis of the image in the requested mode: a full scene description, extracted text (OCR), structured chart data, UI element breakdown, object/subject identification, or a direct answer to a specific question about the image.
