Context

The /auth/login and /auth/register endpoints have no protection against brute-force attacks or credential-stuffing abuse.

Roadmap reference: ROADMAP.md > P1 > Error handling and resilience

What to do

  1. Add a rate-limiting middleware or per-route limiter (e.g. slowapi for FastAPI).
  2. Apply a sensible default (e.g. 10 requests/minute per IP) to both endpoints.
  3. Return HTTP 429 with a Retry-After header when the limit is exceeded.
  4. Make the rate limit configurable via environment variable (AUTH_RATE_LIMIT_PER_MIN).

Acceptance criteria

  • Sending more than the configured number of requests per minute to /auth/login from the same IP returns HTTP 429.
  • The limit is documented in .env.example.
  • A test verifies the 429 response is returned when the limit is breached.
