Ensure Claude development notes stay local only and don't get committed to origin or upstream repositories.
- Replace legacy x402-NP implementation with proper x402 protocol compliance - Create monorepo structure with facilitator, shared packages, and Express server - Implement nanda-points payment scheme to replace blockchain/USDC settlement - Add MongoDB-based transaction handling instead of blockchain verification - Fork and adapt Coinbase x402 Express server for NANDA Points integration - Update PLAN.md with completed Phase 2 tasks and missing documentation requirements - Configure comprehensive .gitignore for clean repository management
- Update PRD.md success criteria to reflect completed implementation - Update PLAN.md Phase 2 deliverables as complete - Create comprehensive README files for shared and facilitator packages - Update Express server README to reflect NANDA Points integration - Remove empty examples folder structure - All package documentation now matches actual implementation
- Document complete x402 payment flow from Requesting Agent perspective - Include detailed 6-step process with actual JSON payloads - Show MongoDB settlement process and balance updates - Document error scenarios and failure cases - Illustrate X-PAYMENT and X-PAYMENT-RESPONSE header usage - Demonstrate NANDA Points integration with x402 protocol compliance
- Full x402 HTTP 402 response compliance working - X-PAYMENT and X-PAYMENT-RESPONSE header processing functional - Express server successfully handles payment middleware - Facilitator service validates payments and generates receipts - Comprehensive testing confirms protocol compliance - Payment flow works end-to-end but uses simulated DB transactions - Ready for Claude Web testing with payment simulation mode
- Remove all legacy x402-NP implementation files - Replace with clean x402-compliant server infrastructure - Add comprehensive documentation and sequence diagrams - Note: Currently using simulated transactions pending real DB integration
- Mark real MongoDB transaction processing as completed in PRD.md - Document integration with working payment code from main branch - Update PLAN.md to reflect successful replacement of simulated transactions - Facilitator now executes actual balance updates, transactions, and receipts
## TypeScript & Linting Improvements - Added proper ESLint configuration with typescript-eslint - Created .prettierrc.json for consistent code formatting - Fixed all TypeScript strict mode issues and linting errors - Added proper type annotations (Db, removed any types) - Structured tsconfig.json with project references ## Documentation Enhancements - Added comprehensive testing prompts to README.md - Included sample prompts for free and paid resources - Added database verification and error scenario prompts - Provided clear examples for x402 protocol testing ## Comprehensive Testing - Created detailed test.log with full HTTP conversations - Tested all endpoints: free (/health, /weather) and paid (/premium/*) - Verified x402 protocol compliance with proper headers - Tested error scenarios: insufficient balance, invalid agent, malformed payment - Confirmed database transactions and balance updates - Validated X-PAYMENT and X-PAYMENT-RESPONSE headers ## Bug Fixes - Made /weather endpoint truly free (removed from payment middleware) - Fixed facilitator type annotations and unused parameter warnings - Ensured proper MongoDB transaction processing ## Test Results Summary ✅ Zero TypeScript/linting errors ✅ Complete x402 protocol compliance ✅ Real database transaction processing ✅ Proper error handling for all scenarios ✅ Free/paid endpoint differentiation working ✅ Payment verification and settlement functional
- Change Express server from port 4021 to 3000 - Change facilitator from port 4022 to 3001 - Update all documentation and configuration files - Complete PLAN.md with all phase completion status - Add comprehensive API documentation in docs/ directory
- CLAUDE.md -> X402-CLAUDE.md - PLAN.md -> X402-PLAN.md - PRD.md -> X402-PRD.md Clear distinction from SDK planning documents.
