Rate Limits

SilentAuth enforces per-project rate limits to ensure fair usage and platform stability. Limits are measured as requests per minute (RPM) and apply per API key.

Limits by Plan

Rate Limit Headers

Every API response includes rate limit headers:

X-RateLimit-Limit:     1000
X-RateLimit-Remaining: 847
X-RateLimit-Reset:     1705312260  # Unix timestamp when limit resets
