"Ray" matching MCP connectors:

Monetization gateway for MCP servers. Agents call a tool, receive an x402 v2 payment challenge, sign a USDC transfer on Base, and get the result. Payment is verified before the tool runs and settled only after it returns, so failed calls are never charged. Discovery and tool listing are free.

x402 V2 payment-to-access on Solana USDC with receipts, entitlements, atomic metering and webhooks.

Wallet-approved SOL and Solana USDC payments to verified X handles, with zero custody.
