​
Icon System

Each provider has a distinct icon for visual recognition:

  • Gemini CLI: Google Gemini sparkle
  • Kiro: CodeWhisperer icon
  • Copilot: GitHub Copilot logo (auto-inverts in dark mode)
  • Claude: Anthropic Claude logo
Icons automatically adapt to light/dark themes for optimal visibility.

​
Quota Aggregation

​
Model Grouping

ZeroLimit intelligently groups models by family: 
Antigravity Account
├── Claude/GPT (avg 45%)
│   ├── claude-sonnet-4-5-thinking
│   ├── claude-opus-4-5-thinking
│   └── claude-sonnet-4-5
├── Gemini 3 Pro (avg 67%)
│   ├── gemini-3-pro-high
│   └── gemini-3-pro-low
└── Gemini 2.5 Flash (avg 82%)
    ├── gemini-2.5-flash
    └── gemini-2.5-flash-thinking

​
Average Calculation

For each group:
  • Individual model percentages are summed
  • Divided by number of models in group
  • Rounded to nearest integer
  • Displayed with group icon and color coding

​
Best Practices

Connect multiple providers to avoid single points of failure. If one service is down or quota is exhausted, switch to another.
Use consistent email naming for personal vs. work accounts (e.g., [email protected] vs. [email protected]).
If using Standard CLI Proxy, note which providers require Plus and plan your upgrade accordingly.
For Gemini CLI, use project IDs to separate dev, staging, and production quotas.

​
Adding New Provider Support

ZeroLimit’s architecture supports easy addition of new providers. The CLI Proxy API handles:
  • OAuth endpoints and callback routing
  • Token refresh logic
  • Quota API integration
  • Provider-specific metadata
Future provider additions are planned based on user demand.

​
Provider-Specific Quota APIs

Each provider uses a different quota API:
  • Antigravity: Custom management API with model buckets
  • Codex: OpenAI backend API with account credits
  • Gemini CLI: Google Cloud quota buckets by project
  • Kiro: AWS usage metrics endpoint
  • Copilot: GitHub internal usage API
  • Claude: Anthropic account dashboard API
ZeroLimit normalizes these into a unified percentage-based display.

​
Troubleshooting

​
Provider Won’t Connect

  1. Verify CLI Proxy is running
  2. Check if provider service is operational
  3. Clear browser cache and retry OAuth
  4. Ensure correct version (Standard vs. Plus)
  5. Check firewall allows localhost:8317

​
Quota Not Updating

  1. Click refresh button on individual provider card
  2. Verify internet connection
  3. Check if account is suspended on provider website
  4. Try deleting and re-adding the account
  5. Review CLI Proxy logs for API errors

​
Plus-Only Provider Shows Lock

Switch to CLI Proxy Plus version:
  1. Go to Settings → CLI Proxy
  2. Click Switch to Plus
  3. Wait for download and restart
  4. Return to Providers page and connect
