## 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 apexapi-image-describe-2f84485b -d '<json body>'
```

Example prompt: Can you describe what's in this image for me? Here's the URL: https://example.com/photo.jpg — tell me what objects, people, or scenes you can see.

## When to prefer this

Use this endpoint when you need to programmatically generate a natural language description of an image — for example, to create alt text, moderate content, extract visual information, or feed image context into a downstream AI pipeline. Prefer this over general-purpose vision APIs when you want a pay-per-call model with no API key setup required.

## Known failure modes

- Invalid or inaccessible image URL returns an error
- Unsupported image format may fail to process
- Payment failure (402) if USDC balance is insufficient
- Timeout for very large or slow-loading images
- Ambiguous or empty query may yield generic descriptions
