Quick Start

// Check current balance
const balance = await mcp__flow-nexus__check_balance();
console.log(`Credits: ${balance.credits}, Auto-refill: ${balance.auto_refill}`);

  amount: 50  // USD minimum $10
});

// Configure auto-refill
await mcp__flow-nexus__configure_auto_refill({
  enabled: true,
  threshold: 100,
  amount: 50
});

// View transaction history
const history = await mcp__flow-nexus__ruv_history({
  user_id: "user_id",
  limit: 20
});

})

Usage Statistics

Usage Examples

Example 1: Balance Management

// Check current balance
const balance = await mcp__flow-nexus__check_balance();

console.log(`
Current Balance: ${balance.credits} credits
Tier: ${balance.tier}
Auto-refill: ${balance.auto_refill ? 'Enabled' : 'Disabled'}
`);

// If balance is low, show warning
if (balance.credits < 100) {
  console.log("Warning: Low balance! Consider adding credits.");

  // Create payment link
  const payment = await mcp__flow-nexus__create_payment_link({
    amount: 50
  });

  console.log(`Purchase credits: ${payment.payment_url}`);
  console.log(`This will add ${payment.credits_amount} credits`);
}

Example 2: Setting Up Auto-Refill

// Check current auto-refill status
const balance = await mcp__flow-nexus__check_balance();

if (!balance.auto_refill) {
  // Configure auto-refill to prevent service interruption
  await mcp__flow-nexus__configure_auto_refill({
    enabled: true,
    threshold: 100,          // Refill when below 100 credits
    amount: 50               // Add $50 worth of credits
  });

  console.log("Auto-refill configured:");
  console.log("- Trigger: When balance falls below 100 credits");
  console.log("- Amount: $50 (~500 credits)");
}

// To disable auto-refill
// await mcp__flow-nexus__configure_auto_refill({ enabled: false });

Example 3: Tracking Usage and Spending

// Get user statistics
const stats = await mcp__flow-nexus__user_stats({
  user_id: "your_user_id"
});

console.log(`
=== Usage Summary ===
Credits Earned: ${stats.credits_earned}
Credits Spent: ${stats.credits_spent}
Net Balance Change: ${stats.credits_earned - stats.credits_spent}
`);

// Get detailed transaction history
const history = await mcp__flow-nexus__ruv_history({
  user_id: "your_user_id",
  limit: 20
});

console.log("\nRecent Transactions:");
for (const tx of history.transactions) {
  const sign = tx.amount > 0 ? '+' : '';
  console.log(`${tx.date}: ${sign}${tx.amount} - ${tx.description}`);
}

// Get payment history
const payments = await mcp__flow-nexus__get_payment_history({
  limit: 10
});

console.log("\nRecent Payments:");
for (const payment of payments.payments) {
  console.log(`${payment.date}: $${payment.amount} - ${payment.status}`);
}

Example 4: Tier Upgrade

// Check current tier and credits
const balance = await mcp__flow-nexus__check_balance();

console.log(`Current tier: ${balance.tier}`);

// Compare tiers
const tierComparison = {
  free: { credits: 100, price: 0 },
  pro: { credits: 1000, price: 29 },
  enterprise: { credits: "Unlimited", price: "Custom" }
};

if (balance.tier === "free") {
  console.log("\nUpgrade Benefits:");
  console.log("- Pro: 10x more credits (1000/month) for $29/month");
  console.log("- Priority access to new features");
  console.log("- Email support");

  // Upgrade to Pro
  const upgrade = await mcp__flow-nexus__user_upgrade({
    user_id: "your_user_id",
    tier: "pro"
  });

  console.log(`\nUpgraded to ${upgrade.new_tier}!`);
  console.log(`Monthly credits: ${upgrade.monthly_credits}`);
}

Example 5: Cost Optimization Analysis

// Analyze spending patterns
const history = await mcp__flow-nexus__ruv_history({
  user_id: "your_user_id",
  limit: 100
});

// Group by category
const spending = {};
for (const tx of history.transactions) {
  if (tx.amount < 0) {
    const category = tx.type || 'other';
    spending[category] = (spending[category] || 0) + Math.abs(tx.amount);
  }
}

console.log("Spending by Category:");
for (const [category, amount] of Object.entries(spending)) {
  console.log(`- ${category}: ${amount} credits`);
}

// Optimization recommendations
console.log("\nOptimization Tips:");
console.log("1. Use appropriate sandbox sizes (don't over-provision)");
console.log("2. Batch operations to reduce overhead");
console.log("3. Leverage templates instead of rebuilding");
console.log("4. Schedule non-urgent tasks for off-peak times");
console.log("5. Clean up unused sandboxes promptly");

Execution Checklist

• Check current balance before operations
• Set up auto-refill to prevent interruptions
• Review spending patterns regularly
• Consider tier upgrade if usage is high
• Track earnings from published content
• Optimize resource usage for cost efficiency

Best Practices

1. Monitor Balance: Check balance before heavy operations
2. Auto-Refill: Enable to prevent service interruption
3. Right-Size Resources: Don't over-provision sandboxes
4. Batch Operations: Group related tasks to minimize overhead
5. Template Reuse: Leverage existing templates
6. Resource Cleanup: Delete unused sandboxes promptly

Cost Optimization Strategies

Error Handling

Metrics & Success Criteria

• Credit Utilization: Track credits used vs available
• Cost per Operation: Monitor average cost by type
• Auto-Refill Success: >99% successful refills
• Revenue (publishers): Track earnings from apps/templates

  source: "challenge"
});

With App Store

// Revenue from published apps
const stats = await mcp__flow-nexus__user_stats({
  user_id: "publisher_id"
});
console.log(`Earned from apps: ${stats.app_revenue} credits`);
