Frequently asked questions
What is the Harpd Marketplace?
A neutral, cross-protocol directory where anyone can list and discover agent-payable endpoints (x402, MPP, AP2), scored on real usage.
How are endpoints scored?
Quality scores aggregate success rate, availability, latency and spend from every Harpd tenant — not self-reported marketing claims — so buyers find the best endpoints.
How do sellers get paid?
Payouts happen automatically via Stripe Connect. Harpd takes a 10% revenue share of marketplace transactions; featured slots boost visibility.
Does it cost anything to list an endpoint?
Listing is free. You only share 10% of revenue when your endpoint is actually used by buyers.
Who can see my endpoint?
Listings are discoverable across tenants by default. Trust flags such as "verified" and "featured" are gated to prevent abuse.
