✓ Within weekly limit (0.015/0.05 SOL used)
✓ Within monthly limit (0.08/0.2 SOL used)
✓ Sufficient balance available

Step 3: Autonomous Processing

⏳ Processing payment automatically...

Example Requests

Data Access

"Get me the latest Bitcoin price from CoinGecko"
"Fetch weather forecast for New York for the next 7 days"
"Pull financial market data for TSLA stock"

AI Services

"Generate an image of a sunset over mountains"

"Process this text and summarize it"

Storage Services

"Pin this file to IPFS"
"Store my data on decentralized storage"

Web3 Services

Conversation Techniques

Building Context

Yuki402 remembers your conversation throughout the session:

You: "Get me weather data for London"
Yuki402: [Provides London weather]

You: "Now compare it to Paris weather"
Yuki402: [Fetches Paris data and compares with London]

You: "Which city is warmer?"
Yuki402: [Analyzes both results and answers]

Context Scope

• Remembers entire session history

• References previous services accessed

• Maintains awareness of prior payments

• Resets when you refresh the page

Follow-Up Questions

Build on previous interactions:

You: "Generate an AI image of a cat"
Yuki402: [Processes payment, generates image]

You: "Make it more colorful"
Yuki402: [Understands context, generates variation]

You: "How much did that cost in total?"
Yuki402: [References transaction history, provides sum]

Multiple Requests

Sequential Approach

Get me weather data
[Wait for response]
Now get Bitcoin price
[Wait for response]

Batch Approach (Recommended!)

I need three things:
1. Weather data for NYC
2. Current Bitcoin price
3. IPFS pinning for my file

Please process all of these.

The batch approach is more efficient and may save on gas fees through optimized transaction batching.

Comparative Queries

Request multiple services and compare:

Get weather data from WeatherAPI and OpenWeather,
then tell me which is more accurate and cost-effective.

Yuki402 will access both services and provide analysis.

Request Types

Service Discovery

Learn about available services:

• "What x402 services can you access?"

• "Show me available AI image generation services"

• "Which weather APIs are supported?"

Direct Service Requests

Access specific services with payment:

• "Use Heurist Mesh to generate [image description]"

• "Get data from WeatherAPI for [location]"

Payment Queries

Check spending and transaction status:

• "How much have I spent today?"

   Required: 0.01 SOL (service + gas)
   Balance: 0.005 SOL

   Please add at least 0.005 SOL to your wallet
   to complete this request.

   2. Increase your daily limit
   3. Use a different connected wallet

Solution: Choose one of the suggested options.

Service Unavailable

❌ Service temporarily unavailable
   Service: WeatherAPI
   Status: 503 Service Unavailable

   ⟳ Retry in 30 seconds? [Yes] [No]
   Or try alternative service? [Show alternatives]

Solution: Wait and retry, or use an alternative service.

Transaction Failed

❌ Transaction failed
   Hash: 0x1234...
   Reason: Gas price too low

   Your funds were NOT deducted.

   ⟳ Retry with higher gas? [Yes] [No]

Solution: Retry with adjusted gas settings, or contact support if issue persists.

Payment Pending

⏳ Payment is taking longer than usual
   Hash: 0x1234...
   Status: Pending (2 minutes)

   This is likely due to network congestion.
   Your payment will process automatically.

   [View on Block Explorer]

Solution: Be patient. Blockchain confirmations can take time during high network activity.

Advanced Techniques

Conditional Requests

If WeatherAPI costs more than 0.002 SOL,
use OpenWeather instead. Get me data for Seattle.

Yuki402 evaluates conditions and makes smart decisions.

Service Preferences

For all future weather requests, prefer WeatherAPI
unless it's more than 50% more expensive than alternatives.

Set preferences for recurring request patterns.

Batch Processing

I need to pin 10 files to IPFS. Here are the CIDs:
[list of CIDs]

Process them all and give me a total cost estimate first.

Efficient bulk operations with cost transparency.

Cross-Chain Requests

Get this data using the cheapest available blockchain,
whether that's Ethereum, Polygon, or Solana.

Let Yuki402 optimize for cost across chains.

Best Practices

Troubleshooting

AI Not Responding

• Wait 30 seconds (may be processing complex request)

• Check internet connection

• Refresh page if stuck >1 minute

• Try simpler query to test connectivity

Service Not Found

• Verify service name or check available services

• Ask "What services are available for [use case]?"

• Service may not support x402 protocol yet

• Try alternative service providers

Payment Not Processing

• Check wallet connection status

• Verify sufficient balance for payment + gas

• Ensure spending limits allow transaction

• Check blockchain network status

Unexpected Costs

• Ask for cost breakdown: "Why did that cost [amount]?"

• Remember to account for gas fees

• Network congestion can increase gas costs

• Some services have dynamic pricing

Tips for Power Users

1. Set Service Preferences: Tell Yuki402 your preferred providers

2. Batch Requests: Combine multiple requests to save on gas

3. Monitor Gas Prices: Ask about current gas costs before transacting

4. Use Aliases: "Do the same thing as last time" works!

5. Request Estimates: "How much would it cost to..." before committing

6. Export History: "Export my transaction history as CSV"

7. Set Up Alerts: "Notify me when I reach 80% of daily limit"

8. Multi-Chain Optimization: "Always use the cheapest chain available"

Common Scenarios

Scenario 1: Regular Data Access

You: "I need weather data for London every morning"

Yuki402: "I can help with that! Each request will cost
         approximately 0.001 SOL. Would you like me to:

         1. Process each request as you ask
         2. Set up automated daily requests (coming soon)

         For now, just ask each morning and I'll handle
         the payment automatically."

Scenario 2: Cost Comparison

You: "What's the cheapest way to get AI-generated images?"

Yuki402: "Here are the available x402 AI image services:

         1. Heurist Mesh: 0.002 SOL per image
         2. Alternative AI: 0.0015 SOL per image

         Alternative AI is currently 25% cheaper.
         Which would you like to use?"

Scenario 3: Budget Management

You: "I want to use $50 worth of services this month"

Yuki402: "At current SOL prices (~$2,500), that's
         approximately 0.02 SOL.

         Recommended limits:
         - Daily: 0.001 SOL (~$2.50)
         - Weekly: 0.005 SOL (~$12.50)
         - Monthly: 0.02 SOL (~$50)

         Shall I set these limits for you?"
