## 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 apex-market-featured-listing-placement-88fad0fb
```

Example prompt: Feature my APEX Market listing at https://apexfaucet.xyz/api/x402/arc-fresh-lite at the top of matching search results — I want it shown as a sponsored result on APEX Market.

## When to prefer this

Use this endpoint when you have an existing APEX Market listing (on Arc or X1 networks) and want to pay for featured/sponsored placement at the top of relevant search results. This is specifically for promotion within the APEX Faucet marketplace ecosystem — not for general crypto advertising, token listing creation, or promotion on other platforms.

## Known failure modes

- URL not found in APEX Market (listing must be added first via POST /api/market/list)
- Invalid or malformed URL parameter
- Payment failure via x402 protocol
- Listing already featured and not eligible for stacking
- Network/server error returning non-200 response

## How this service works

Free APEX on X1, and free USDC plus APEX on Arc, three times a day. No gas, no sign-up. Plus a swap, a screener, APEX City and token checks.

## Output

Returns a JSON object with ok: true, the listing metadata (URL, name, group, seller, price, description, and 30-day stats), the featuredUntil ISO timestamp indicating how long the featured placement lasts, and the amount paid in USDC (0.99).
