AI Chat Interface
The heart of Mika402 is its intelligent chat interface, powered by Google Gemini AI, designed to understand your service requests and autonomously process payments via the x402 protocol.
Overview
The AI chat interface enables natural, conversational interaction with autonomous payment capabilities. You don't need to learn payment protocols or blockchain commands—just describe what service you need in plain English, and Mika402 handles the rest: discovering x402 services, processing payments, and delivering results.

How the AI Works
Natural Language Understanding
The AI processes your requests through advanced natural language processing:
Intent Recognition
Understands what service you need (weather data, AI generation, storage, etc.)
Identifies service preferences ("use the cheapest option", "fastest service")
Recognizes urgency and priority levels
Interprets follow-up requests in context
Service Mapping
Translates natural requests to x402 service categories
Maps informal descriptions to specific API capabilities
Understands service synonyms (e.g., "store file" → IPFS pinning)
Recognizes blockchain and payment preferences
Context Awareness
Remembers previous service requests in conversation
Understands references to earlier transactions
Maintains awareness of your spending limits
Adapts to your usage patterns
x402 Service Discovery
The AI automatically discovers compatible services:
Registry Queries
Searches x402 service registry in real-time
Filters by your requirements (price, speed, features)
Checks service availability and uptime
Validates service compatibility with your wallet
Service Comparison
Compares multiple providers for the same service type
Evaluates pricing, reliability, and performance
Suggests optimal service based on your criteria
Explains trade-offs between options
Autonomous Payment Processing
The AI handles payments automatically:
Pre-Payment Checks

Service History
Spending Awareness
Service Preferences
Request Types
Direct Service Requests
Ask for specific services:
"Get me weather data for New York"
"Generate an AI image of [description]"
"Pin my file to IPFS"
"Fetch Bitcoin price from CoinGecko"
AI Response: Finds service, processes payment, delivers data
Service Discovery
Explore available options:
"What x402 services can you access?"
"Show me available weather APIs"
"Which image generation services do you support?"
"List all data APIs under 0.001 ETH per request"
AI Response: Searches registry, provides list with pricing
Price Comparison
Compare service costs:
"What's the cheapest weather API?"
"Compare IPFS pinning services"
"Show me price differences for image generation"
"Find the most cost-effective data API"
AI Response: Compares options, recommends based on criteria
Spending Management
Check and manage spending:
"How much have I spent today?"
"Show my transaction history"
"Update my daily limit to 0.02 ETH"
"What's my remaining weekly budget?"
AI Response: Provides spending reports and updates limits
Service Configuration
Manage preferences:
"Prefer Solana over Ethereum for lower gas fees"
"Always ask before payments over 0.005 ETH"
"Use the fastest service regardless of cost"
"Optimize for price over speed"
AI Response: Saves preferences, applies to future requests
Best Practices
Asking Effective Questions
Be Specific About Requirements
❌ "Get me some data" ✅ "Get me 7-day weather forecast for San Francisco with hourly breakdown"
Specify Budget Constraints
❌ "Generate an image" ✅ "Generate an image but only if it costs less than 0.002 ETH"
Indicate Preferences
❌ "Pin my file" ✅ "Pin my file using the fastest IPFS service available"
Optimizing Costs
Batch Requests
Set Price Limits
Choose Appropriate Chains
Managing Spending
Monitor Regularly
Check daily spending: "How much have I spent today?"
Review transactions: "Show my last 10 payments"
Track by service: "How much have I spent on weather APIs?"
Set Conservative Limits
Start small: Daily limit of 0.01 ETH while learning
Increase gradually: Adjust based on actual usage
Use separate limits: Different limits for different service types (coming soon)
Get Estimates First
Understanding Limitations
Payment Constraints
Spending Limits
AI will refuse requests that exceed limits
Cannot bypass limits even if you ask
Limits protect you from accidental overspending
Balance Requirements
Need sufficient crypto for service + gas fees
AI estimates but gas can vary with network conditions
Keep buffer in wallet for unexpected gas spikes
Transaction Finality
Blockchain transactions are irreversible
AI cannot cancel after submission
Failed transactions refund automatically
Service Availability
Dependency on x402 Ecosystem
Only accesses x402-compatible services
Service availability depends on providers
Some traditional APIs may not be available yet
Network Conditions
Blockchain congestion affects confirmation times
High gas prices during network stress
Service providers may experience downtime
AI Capabilities
Not Financial Advice
AI processes payments, doesn't give investment advice
Focuses on service access, not speculation
Transparent about costs, not price predictions
Service Selection
Chooses based on explicit criteria (price, speed, etc.)
Cannot predict service quality without trying
Relies on registry data for service information
Rate Limiting
Purpose
Rate limiting ensures:
Fair Access: Equal opportunity for all users
System Stability: Prevents overload
Cost Control: Prevents accidental rapid spending
Abuse Prevention: Stops automated exploitation
How It Works
Per-Message Cooldown
50-second wait between messages (currently)
Persistent across page refreshes
Tracked in browser local storage
Cannot be bypassed
Working Within Limits
Batch multiple requests in one message
Plan requests during cooldown period
Use waiting time to review responses
Ask comprehensive questions to reduce round-trips
Privacy & Security
Data Handling
Conversations
Not stored on servers
Not logged or tracked
Exist only during session
Refresh page to clear
Transactions
Public on blockchain (nature of blockchain)
Transaction hashes are permanent records
Wallet addresses visible on-chain
Service data privacy depends on provider
Wallet Security
Non-Custodial
You control your private keys
Mika402 never accesses your seed phrase
Can revoke wallet connection anytime
Spending limits enforce maximum amounts
Best Practices
Use dedicated wallet for autonomous payments
Start with small amounts while learning
Monitor transaction history regularly
Verify all transaction details on block explorer

Troubleshooting
AI Not Processing Payment
Check:
Wallet is connected
Sufficient balance (service + gas + buffer)
Within spending limits
Service is available
Try:
Reconnect wallet
Add funds if balance low
Increase spending limits if needed
Request alternative service
Service Not Delivering
If payment processed but no data:
Wait 30 seconds (some services slower)
Check transaction on block explorer
Save transaction hash as proof
Contact service provider
Report to Mika402 support
Unexpected Costs
If charged different amount:
Check gas fees separately
Network congestion increases gas
Service may have dynamic pricing
Verify on block explorer
Contact support if genuinely incorrect
Payment Failed
Common reasons:
Insufficient gas
Network congestion
Limit exceeded
Service unavailable
Your funds are safe:
Failed transactions refund automatically
Check block explorer for status
Retry with adjusted parameters
Tips for Power Users
