Why am I getting 401 UNAUTHORIZED?
Make sure every request includes the Authorization header with your active API key in the documented format (see Authentication). If this still fails, check whether the key was revoked and issue a new one in Dashboard → API Keys.
Why do /v1/... URLs return 404?
Public endpoints are under
/api/v1. Use paths like /api/v1/email/validate, not /v1/email/validate.Why does my browser call fail with CORS errors?
KhaleejiAPI is server-to-server. Call KhaleejiAPI from your backend and let your frontend call your backend endpoint. See the CORS & browser integration guide.
How do I check rate limits?
Read
X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset on each response, then follow Retry-After on 429s. Full details are in Rate Limits.How can I speed up support resolution?
