## 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 x402hunt-product-listing-submission-3f325341 -d '<json body>'
```

Example prompt: Submit my AI writing tool 'DraftMind' at draftmind.io to x402hunt — the tagline is 'Write 10x faster with AI', category is 'ai', here's my email: founder@draftmind.io, use the rocket emoji, and open with a $25 payment to get a strong starting rank.

## When to prefer this

Use this endpoint when you want to programmatically submit or launch a product on the x402hunt leaderboard and pay for placement via USDC on Base. It is the right choice when you need a transparent, payment-ranked product directory submission rather than a free or vote-based discovery platform. Prefer this over general product directories when your audience is crypto-native, AI-tool users, or indie hackers who discover via leaderboard, and when the submitter can make an x402 USDC payment on Base.

## Known failure modes

- Missing required fields (url, name, email, tagline, amountUsd) returns a validation error
- Payment below minimum $5 or above $999,999 is rejected
- Invalid or non-HTTPS product URL is rejected
- Malformed email address causes submission failure
- Invalid category string not matching allowed enum values may be rejected or defaulted
- Payment failure on Base network causes listing not to be created
- Duplicate submissions for the same URL may be rejected or treated as rank boosts

## How this service works

Launch any product, website or app: AI tools, SaaS, crypto, indie projects. Placement is a single x402 payment (USDC on Base) and every payment compounds into your rank. Your product does not need x402, only the payment does. Daily, weekly and all-time leaderboards with transparent, payment-based ranking.

## Output

Returns a success flag, a human-readable message, payment details (amount, network, transaction hash), the full created product listing object including its rank total, and a public URL where the listing can be viewed on x402hunt.lol
