Zurri Development Log

Project Overview

Zurri is an AI Agents Marketplace platform with a chat protocol, wallet point system, and Paystack payment integration.

Completed Features

✅ Core Platform Refactoring

• Refactored from models + agents to agents-only marketplace
• Implemented chat protocol for agent communication
• Removed all model-related code
• Updated entities to focus on fully packaged agents

✅ Agent Management

• Agent CRUD operations
• Agent entity with fields: avatar, category, reputation, capabilities, pointsPerTask
• IPFS integration for agent avatars (Pinata)
• Agent listing with filters (category, search)
• Agent status management (pending, approved, rejected)

✅ Chat Protocol

• Standardized chat interface for agent communication
• Message exchange with role-based system (user, assistant, system)
• File and image upload support in chat
• Support for document files and programming language extensions
• IPFS storage for chat files
• Chat history with filters (agentId, role, date range, search)

✅ Wallet Point System

• Wallet entity with balance tracking
• Transaction entity with types: credit, debit, charge, purchase, refund, free
• Point system: 1 point = $0.05
• Free tasks system: First 2 tasks per user are free
• Wallet funding via Paystack
• Transaction history with pagination
• Balance conversion (points ↔ USD)

✅ Payment Integration (Paystack)

• Paystack SDK integration (paystack-node)
• Payment initialization endpoint
• Webhook handler with HMAC signature verification
• Payment callback handler (redirect flow)
• Manual transaction verification endpoint
• Idempotent payment processing (no double-crediting)
• Complete Swagger documentation for all payment endpoints
• Payment flow documentation

✅ Exchange Rate Management

• Dynamic exchange rate service
• Multiple API sources (ExchangeRate-API, CurrencyAPI, Fixer.io)
• Intelligent caching (1-hour cache)
• Fallback to fixed rate if APIs fail
• Automatic adaptation to NGN/USD fluctuations

✅ User Management

• User registration and authentication (JWT)
• User profiles with wallet summary
• User dashboard endpoints (chat history, wallet balance)
• User history with filters

✅ Creator System

• Creator registration with detailed profile
• Creator authentication
• CreatorProfile entity with comprehensive fields:
  • Basic info (fullName, username, bio, profileImage)
  • Professional info (organization, role, website, social links)
  • Technical stack (languages, frameworks, specialties)
  • Payout info (bank account, wallet address, currency)
  • Verification status
• Creator dashboard endpoints (overview, earnings)
• Earnings tracking with time-series data
• Total points earned tracking (gross earnings)

✅ Admin Dashboard

• Admin authentication middleware
• Admin overview endpoint with platform statistics
• Platform metrics (users, agents, messages, points volume)
• Date range filters
• Admin payment exemption for testing unapproved agents
• Admin can test pending/rejected agents without payment
• Admin test transactions tracked separately (ADMIN_TEST type)

✅ IPFS Integration (Pinata)

• Pinata SDK integration

• File upload for avatars
• File upload for chat attachments
• Gateway URL configuration

✅ API Documentation

• Swagger UI integration
• Complete API documentation for all endpoints
• Request/response schemas

• Example values

✅ Security & Best Practices

• JWT authentication with enhanced validation
• Password hashing (bcrypt, 12 rounds)
• Password strength validation (8+ chars, uppercase, lowercase, number, special char)
• Forgot password functionality with secure reset tokens
• Password reset with token expiration (1 hour)
• Change password endpoint for authenticated users
• Account lockout after 5 failed login attempts (30-minute lockout)
• Failed login attempt tracking
• CORS configuration with origin validation
• Helmet security headers (CSP, HSTS, XSS protection, frame guard)
• Rate limiting (general API, auth endpoints, password reset)
• Input sanitization (XSS prevention)
• Request size validation
• Request logging
• Error handling with secure messages
• Environment variable management
• Trust proxy configuration for rate limiting

✅ Deployment

• Dockerfile for Hugging Face Spaces
• Multi-stage build optimization
• Health check endpoint
• Non-root user in Docker
• .dockerignore configuration
• Production-ready configuration

Current Status

✅ Completed

• All core backend features implemented
• Payment system fully functional
• Exchange rate management operational
• Complete API documentation
• Docker deployment ready
• Security enhancements (password reset, account lockout, rate limiting)
• Admin testing capabilities (no payment for unapproved agents)

🔄 In Progress

• None

📋 Pending: Business Model Implementation

Payout System & Commission Model

The following features need to be implemented to complete the business model:

1. Platform Commission System

   • Configure platform commission percentage (e.g., 20-30%)
   • Store commission rate in environment variables or database
   • Calculate creator earnings after platform cut
   • Track platform revenue separately

2. Creator Earnings Calculation

   • Update earnings endpoints to show net earnings (after platform cut)
   • Track gross vs net earnings per transaction
   • Calculate platform revenue from each transaction
   • Display earnings breakdown (gross, platform fee, net)

3. Payout System

   • Create Payout entity (pending, processing, completed, failed)
   • Payout request endpoint for creators
   • Minimum payout threshold (e.g., $10 or 200 points)
   • Payout approval workflow (admin approval)
   • Payout processing (manual or automated via Paystack transfers)
   • Payout history for creators
   • Payout management for admins

4. Financial Tracking

   • Track platform revenue (total commission earned)
   • Track creator payouts (total paid out)
   • Track pending payouts
   • Financial reporting for admins

5. Integration Requirements

   • Paystack transfer API integration for automated payouts
   • Bank account verification for creators
   • Tax document handling (if required)
   • Payout notifications (email/webhook)

📋 Next Milestone: Frontend Development

The frontend will be built in a separate milestone. The backend is ready to serve API requests.
