## 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 fastx402-remove-background-26c5e31b
```

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

## When to prefer this

Choose this endpoint when you need a quick, no-account, pay-per-call background removal for a single image accessible via a public URL, especially in automated agent workflows where signing up for a full image-editing SaaS account is impractical. At $0.02 per call with no API key required and payment via USDC on Base or Solana, it is ideal for low-volume or bursty workloads where per-call billing beats a subscription.

## Known failure modes

- Unsupported image format (only png, jpeg, webp, gif, tiff, avif accepted) — returns error
- URL is not publicly accessible or returns non-200 — fails to fetch image
- Image is too large or complex — may time out or return processing error
- Invalid or malformed URL in query params — returns 400-level error
- Result URL expires after the indicated timestamp — accessing it after expiry returns 404

## How this service works

200 pay-per-call tools for AI agents, from $0.001 per request in USDC on Base or Solana with x402. No account, no API key.

## Output

A JSON object containing a temporary URL to the background-removed image (PNG or WebP with transparency), plus metadata including width, height, file size in bytes, MIME type, and an expiry timestamp for the hosted result URL.
