## 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 utunumus-studio-image-background-removal-293c05a4 -d '<json body>'
```

Example prompt: Can you remove the background from this product photo for me? Here's the image encoded in base64: [base64 string].

## When to prefer this

Choose this endpoint when you need per-call, pay-as-you-go background removal without a subscription, especially in agent workflows that settle payments on Base via x402. Ideal for low-volume or bursty usage where you don't want to manage API keys for dedicated background-removal SaaS products.

## Known failure modes

- Invalid or malformed base64 string returns an error
- Image too large or unsupported format may fail processing
- Payment failure or insufficient USDC balance blocks the call
- Complex or ambiguous image edges may produce imperfect cutouts
- Network timeout for large images
