Rate Limiting per User/API Key Tiering

[grantfox-oss]

Priority: High
Category: Security & Rate Limiting

Description

Implement tiered rate limiting based on user roles and API key tiers. Free users get 100 req/min, paid users 1000 req/min, and enterprise users 10,000 req/min. Current global rate limits are too restrictive for power users.

Definition of Done

• Tiered rate limit configuration
• API key tier management system
• Dynamic rate limit adjustments
• Rate limit headers in all responses
• Billing integration for excess usage

Acceptance Criteria

• Different rate limits applied based on user role/API key tier
• X-RateLimit-Limit, X-RateLimit-Remaining headers returned
• Rate limits configurable via environment variables
• Alerts for users approaching their rate limits
• Billing system can charge for over-limit usage
• Distributed rate limiting works across multiple instances
• Documentation updated with tier specifications

I will implement a scalable tier-based rate limiting system that applies limits dynamically based on user roles and API key subscriptions. The solution will support distributed enforcement across multiple instances, expose standard rate limit headers, provide usage alerts, and integrate with billing for overage handling. This enables fair resource allocation for free users while supporting the higher throughput requirements of paid and enterprise customers.

Hi maintainer, I'd like to take this on. I can implement tiered rate limiting based on user roles and API key plans, add support for configurable limits and distributed enforcement across instances, and integrate usage alerts, billing hooks, and rate-limit headers so higher-tier users can scale their usage without affecting the overall platform.please assign
