What is xPay?
xPay lets you turn any existing HTTP endpoint into a paid microservice with no code changes. It wraps your API with a trust-minimized x402 paywall on Solana (USDC by default), gives you a shareable proxy URL, and auto-publishes your endpoint as an MCP tool discoverable by AI agents.
Why it matters
Own your distribution with cryptographic, per-request payments
Instant settlement to your wallet, near-zero fees, no custody risk
AI-native: your endpoints become MCP tools agents can call directly
No-code onboarding: point to an existing URL, set price/token, share the new link
