x402Lite submission for Learning & Community

[aipin-io]

Description

This PR adds x402Lite Payment Widget, a simple open-source starter project that demonstrates how developers can implement the x402 Protocol and register their endpoints on x402scan.

The repository includes:

• A working /api/x402 Express example (Node.js)
• Step-by-step setup instructions
• MIT license for reuse
• A social share section encouraging users to post their live demo on Twitter/X or Discord

This Learning Kit is designed to help new community members quickly understand x402’s payment-required schema and integrate it into real use cases like pay-per-API or AI-agent micropayments.
