Rate Limiting

API requests are rate-limited using a sliding window algorithm to ensure fair usage and service stability. Limits are applied per API key.

Tier Limits

Tier	Scans / Month	Scans / Minute	API Keys
Free	100	5	1
Pro	5,000	50	5
Enterprise	Unlimited	200	20

Response Headers

X-RateLimit-Limit: 50
X-RateLimit-Remaining: 47
X-RateLimit-Reset: 1740600000

X-RateLimit-Limit -- Maximum requests allowed in the current window
X-RateLimit-Remaining -- Requests remaining in the current window
X-RateLimit-Reset -- Unix timestamp when the rate limit window resets

Rate Limited Response 429 Too Many Requests

{
  "error": {
    "code": "RATE_LIMIT_EXCEEDED",
    "message": "Rate limit exceeded. Please wait before making another request.",
