API rate limiting policies enforce tiered quotas based on developer trust levels (e.g., free tiers allow 100 requests/hour; enterprise tiers offer 10,000+). Policies include burst limits to handle traffic spikes, adaptive throttling based on system load, and geographic restrictions to prevent abuse. Developers receive real-time quota updates via headers, with grace periods for accidental overages. Penalties for repeated violations include temporary blocks or tier downgrades.
