- SDK-PRD.md: Product requirements with decorator-based API vision - SDK-PLAN.md: 3-phase implementation plan with detailed tasks - SDK-CLAUDE.md: Development context and guidelines for new Claude instance Defines scope for standalone developer SDK to simplify x402 payment integration.
- Clarify SDKs are client libraries, not server middleware - Define TypeScript and Python SDKs with language-native APIs - Update monorepo structure to sdks/typescript and sdks/python - Focus on x402 protocol clients and facilitator API wrappers - Remove decorator-based server middleware approach SDKs will provide: npm install @nanda/payments-sdk and pip install nanda-payments
- SDK-CLAUDE.md -> CLAUDE.md - SDK-PLAN.md -> PLAN.md - SDK-PRD.md -> PRD.md Clean SDK branch structure for new Claude instance.
Complete context and guidelines for new Claude instance to develop TypeScript and Python client SDKs for NANDA Points integration.
Update planning documents to reflect completed Phase 1 implementation: - PLAN.md: Mark Phase 1 as completed with all SDK tasks done - PRD.md: Refocus on server-side MCP tool monetization use cases - CLAUDE.md: Document complete implementation architecture and API patterns Phase 1 deliverables completed: - @nanda/payments-sdk package ready for npm publication - MCP utilities: requirePayment(), createPaidTool(), quickSetup() - Express middleware: paymentMiddleware() for route-level protection - Working MCP server examples demonstrating tool monetization - Zero TypeScript compilation errors with full type safety 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Code Quality Improvements: - Fix TypeScript best practices in SDK code - Remove orphaned sdks/typescript directory - Implement proper type safety in quickSetup() function - Complete requirePayment() implementation with actual payment verification - Fix type imports and compilation issues Documentation Enhancements: - Create comprehensive README.md for @nanda/payments-sdk (491 lines) - Update main README.md to prominently feature the new SDK - Add SDK quick start guide with working examples - Update all package READMEs to reference the new SDK - Modernize advanced-server README to reflect NANDA Points instead of blockchain - Ensure all documentation accurately reflects current implementation Quality Assurance: - Zero lint errors across all TypeScript files - Successful TypeScript compilation with full type safety - Comprehensive API documentation with examples - Clear migration guides and usage patterns - Complete error handling documentation The SDK now provides the definitive way to integrate NANDA Points payments into MCP servers and Express applications with developer-friendly APIs.
Create TypeScript adaptation of the Python NANDA Adapter with NANDA Points payment requirements on key endpoints. Based on https://github.com/projnanda/adapter Key Features: - Full TypeScript implementation with Express.js server - Payment integration using @nanda/payments-sdk - Mirrors Python adapter API endpoints and functionality - Adds payment requirements to /api/send (10 NP) and /api/receive_message (5 NP) - Maintains backward compatibility with free endpoints Implementation Details: - Agent bridge communication simulation - Server-Sent Events (SSE) for real-time message streaming - Conversation tracking and message history - Payment statistics and monitoring endpoints - Comprehensive error handling and logging - x402-compliant HTTP 402 responses Test Infrastructure: - Complete package.json with dependencies - TypeScript configuration and build setup - Environment configuration template - Test script for endpoint validation - Comprehensive README with usage examples The adapter demonstrates how to monetize existing API endpoints using NANDA Points while maintaining compatibility with existing clients.
