Usage & Billing

City meters every model call and tracks usage across all connected Agents and products. This is the foundation for billing, quotas, and cost management.

Usage tracking

• Every model request is metered (tokens in, tokens out)
• Usage is aggregated per user, per project, and per model
• Real-time usage dashboards are available in the Console

Balance

• Users maintain a balance account in City
• Balance is consumed as usage accrues
• Low balance triggers alerts
• Auto-recharge can be configured

Billing

City integrates with Stripe for:

• One-time payments
• Subscription plans
• Usage-based billing
• Invoice generation

Quotas

• Soft quotas warn before limits are reached
• Hard quotas block requests when exceeded
• Quotas can be configured per user, per project, or per model
