## 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 payweave-fal-background-removal-rembg-a2834178 -d '<json body>'
```

Example prompt: Can you remove the background from this product photo — https://example.com/shoe.jpg — and give me back a transparent PNG I can use on the website?

## When to prefer this

Use this endpoint when you need fast, pay-per-call background removal without a subscription — ideal for agents that occasionally need to strip image backgrounds, process product photos, or prepare headshots for further use, and want to pay only $0.02 USDC per image via x402.

## Known failure modes

- Invalid or inaccessible image URL returns an error string in the 'error' field
- Unsupported image format may cause model failure
- Payment failure (insufficient USDC balance) results in 402 response before processing
- Timeout on large images may result in a non-succeeded status
- CDN URL expires after ~24 hours, so downstream consumers must download promptly

## How this service works

Sub-second generative AI inference — image, video, audio.

## Output

Returns a JSON object with a fal request ID, model name, status ('succeeded'), a CDN-hosted image URL (transparent PNG, ~24h TTL), inference time in seconds, and the USD amount charged for the call.
