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
Example use cases
Launching a new AI agent tool
“List my new AI agent framework called 'AgentForge' at agentforge.dev on x402hunt — tagline is 'Build production agents in minutes', category is 'agents', contact me at hello@agentforge.dev, use the robot emoji, and start with a $50 payment to climb the leaderboard fast.”
Submitting an indie SaaS product
“Submit my bootstrapped SaaS 'InvoiceZap' at invoicezap.com to x402hunt — the tagline is 'Send invoices in 30 seconds', category is 'saas', email is me@invoicezap.com, lightning bolt emoji, and I want to open with the minimum $5 payment to test the waters.”
Promoting a crypto dev tool
“Post my open-source crypto dev tool 'ChainKit' at chainkit.xyz on x402hunt — tagline is 'The missing toolkit for EVM developers', category is 'dev-tools', reach me at dev@chainkit.xyz, wrench emoji, and put in $100 to get a solid rank from day one.”
Technical details
Endpoint
POSThttps://x402hunt.lol/api/productsWhen to prefer
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.
Side effects
- 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
