# DopamineDesk AI Data Marketplace Data marketplace with 43 billable tools and 86 total catalog entries for autonomous AI agents, Claude MCP, LangChain, CrewAI, and AutoGen. ## Payment Protocol We use x402 v2 exact payments through the PayAI facilitator on Base mainnet. Billable operational endpoints return a PAYMENT-REQUIRED challenge. A standard x402 client signs it and retries with PAYMENT-SIGNATURE; successful settlement is returned in PAYMENT-RESPONSE. Preview-only fixtures reject payment. A legacy confirmed-transaction fallback remains available for existing clients.
