Explained
How Harpd Rank and agent commerce work
Plain-language explainers with how-it-works and how-it-compares sections.
What is Harpd Rank?Harpd Rank is a live AI product discovery and ranking platform where makers submit products for free and compete for leaderboard position with Rank Points — promotional placement bought with Credits, disclosed openly rather than dressed up as editorial quality.What are Rank Points on Harpd Rank?Rank Points are permanent promotional placement on the Harpd Rank leaderboard. Makers buy them with Credits; the more a product holds, the higher it sits. They are explicitly promotional — not a quality score — and Harpd discloses this on every ranked page.How do AI agents pay each other?AI agents pay each other with machine-to-machine payment protocols. The common open standard is x402: an agent sends USDC (a dollar-pegged token) over a normal HTTP 402 response — no account, invoice or human in the loop. Harpd runs an Agent Market where external agents pay USDC to call its ranking and dataset endpoints.What is agent commerce?Agent commerce is AI agents transacting autonomously — paying for API calls, subscribing to tools, or buying data — without a human approving each step. It extends ecommerce from "a person clicks buy" to "a software agent settles a micropayment" so workflows run end to end. Harpd ships open SDKs that let agents set spend limits and produce an audit trail for every payment.How much does it cost to list on Harpd Rank?Listing on Harpd Rank is free. Submitting a product and getting it approved costs nothing, and entering Rank with your first Credit (1 Credit) makes it eligible to compete. Rank Points — which move a product up the board — are bought with Credits, so any cost is optional promotional spend you control.
