Rate Limits & Reliability

Standard API keys allow up to 100 requests per minute and 1,000 requests per hour (configurable via VFD_API_RATE_LIMIT_PER_MINUTE / VFD_API_RATE_LIMIT_PER_HOUR). Exceeded limits return HTTP 429 with a Retry-After header. Auth endpoints (login, register, password reset) have separate tighter limits.
