## 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 productclank-product-listing-957a839f -d '<json body>'
```

Example prompt: List my product on ProductClank — the website is https://acme.com, the name is Acme, and the tagline is 'The fastest way to manage invoices'. Add it under the 'productivity' and 'finance' categories and use my Twitter @acmehq.

## When to prefer this

Use this endpoint when a builder or founder wants to get their product discovered by real users through the ProductClank directory, especially when they want distribution without upfront ad spend. It is ideal for launching new products, indie tools, or SaaS apps. Prefer this over generic Product Hunt-style submissions when the user wants an automated, API-driven listing with x402 micropayment-based access and auto-metadata extraction from a product URL.

## Known failure modes

- Product URL is unreachable or returns errors — listing cannot be auto-filled
- Name is missing and no URL is provided to auto-resolve it — validation error
- Payment fails or is underfunded — listing not created
- Product already listed — returns already_listed: true with existing listing details
- Invalid logo URL or inaccessible image — logo auto-resolution fallback may be used
- Category tags are unrecognized or malformed — may be ignored or cause an error

## How this service works

Real people start taking action for your product. Up in minutes, and your first campaign is free. ProductClank gives builders distribution instead of asking for capital.

## Output

Returns a JSON object confirming the payment settlement on Base (EIP-155), the new product listing ID, the public listing URL on productclank.com, the product's website, whether it was featured, and whether it was already listed. Also includes the directory index URL.
