Runs a WHOIS lookup for a domain, IP, or ASN and returns normalised info into canonical fields.
api.dazrik.net
A small collection of public and free to use HTTP APIs including WHOIS, port checks, DNS resolution, and HTTP probes.
Base URL
Section titled “Base URL”Every endpoint is under https://api.dazrik.net and is a plain GET request with URL query parameters.
Responses
Section titled “Responses”Every response is JSON with an ok boolean. When ok is true, the returned response includes the endpoint’s specific fields, when it is false, msg explains what went wrong. Targets that resolve to a private or reserved address are refused. Cross-origin requests are allowed, so these endpoints can be called directly from the browser.
Authentication and limits
Section titled “Authentication and limits”The API is public and free to use, so no API key is needed. It is rate limited to 60 requests per minute per client IP. Every response includes the standard RateLimit/RateLimit-* headers reporting your remaining budget, and exceeding the limit returns a 429 with a Retry-After header.
Do note that you can get banned from using the API if at any point I don’t like the requests that you’re sending.
Resolves a target to a single public IP and tests whether a TCP port is open.
Looks up a hostname’s A/AAAA addresses, or a specific record type (MX, SOA, TXT, etc) as structured values.
Probes an http(s) target and reports its status, headers, and final URL after redirects.
