# PayAI Ecosystem Projects building on PayAI and the x402 protocol: agents that pay, services that charge per request, and infrastructure that connects them. This page lists ecosystem projects, not a complete or continuously verified service inventory. GET https://facilitator.payai.network/discovery/resources returns the Bazaar catalog, including last-recorded payment terms and seller-declared schemas when available. Entries can persist without refresh; a listing is not proof of current availability, successful settlement or service quality. Inspect lastUpdated, then obtain current requirements from the provider before paying.
