## 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 agentpay-image-describe-e583d286 -d '<json body>'
```

Example prompt: Can you describe what's in this image for me — list all the objects you can see and give me a summary of what the photo shows? Here's the URL: https://example.com/photo.jpg

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call image description without account setup or API key management. Ideal for agents that process images infrequently or on-demand and want to avoid subscription costs. Particularly suited for crypto-native pipelines already using the x402 protocol and USDC on Base.

## Known failure modes

- Invalid or inaccessible image URL returns an error with no description
- Insufficient USDC balance or failed x402 payment results in 402 Payment Required with no analysis
- Unsupported image format may result in processing failure
- Network timeout if image host is slow to respond
- Ambiguous or very low-quality images may yield sparse object lists and vague descriptions

## How this service works

Pay-per-call AI services via the 402 Payment Required protocol. No accounts, no API keys — just USDC on Base.

## Output

Returns a JSON object with two fields: 'objects' (an array of strings naming detected items in the image) and 'description' (a natural-language string summarizing the image content). The response is delivered after a microtransaction of $0.03 USDC on Base is settled via the x402 protocol.
