Rate Limiting

Per-IP, per-user, per-API-key rate limits using Laravel's RateLimiter or a custom Redis-backed sliding window. Different limits for read vs write endpoints, with 429 + RFC 7807 problem responses including Retry-After headers. Throttled login routes block credential stuffing at the application layer.

3 projects and 20 packages carry this capability.
