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.
Example use cases
Solo founder launching new SaaS
“Submit my new tool to ProductClank so real people can find it — the site is https://myscheduler.app, name is MyScheduler, tagline is 'Effortless calendar blocking for makers', and my Twitter is @myschedulerapp.”
No-code builder seeking early users
“Get my no-code product listed on ProductClank to start getting users — the URL is https://bubbletool.io, the product is called BubbleTool, and the category should be 'no-code' and 'productivity'.”
Agency launching client product
“Create a ProductClank listing for my client's product — the website is https://clientapp.com, name is ClientApp, tagline is 'CRM built for freelancers', and categories are 'crm' and 'freelance'.”
Technical details
Endpoint
POSThttps://www.productclank.com/api/x402/product-listingWhen to prefer
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.
Side effects
- 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
