Base URLhttps:
- GET/security
/vpn-proxy-detectorNo price listedChecks an IPv4 address against the public X4BNet list of commercial VPN provider address ranges (about 11,000 CIDR blocks, refreshed by the list's maintainer). Returns whether the address falls in a listed VPN range and which range. A miss does not prove a direct connection, and IPv6 is not covered. - GET/security
/openphish-feedNo price listedChecks a URL or host against the OpenPhish public phishing feed (about 300 currently active phishing URLs, updated continuously). Returns whether the exact URL or any URL on the same host is listed, the feed size and up to 5 example URLs. Not listed does not mean safe; the feed is short and changes fast. - GET/search
/wordpress-articlesNo price listedWordPress.org news posts from the official WordPress news RSS feed (keyword filter on title/summary/categories). Latest posts only. Public feed, no key. - GET/security
/shodan-host-summaryNo price listedShodan InternetDB summary for an IPv4 address (free, no key): open TCP ports, host names seen, CPE software identifiers, tags and CVE IDs Shodan associates with the host. Data is from Shodan's last scan, so it can be days old; an IP with no data returns empty lists with known=false. - GET/search
/doj-press-releasesNo price listedUS Department of Justice press releases from the justice.gov public RSS feed (keyword filter on title/summary). Latest items only. Public feed, no key. - GET/security
/cve-details-feedNo price listedVulnerability trend for a vendor (optionally one product) from the NIST NVD: CVEs published in the last N days (default 7, up to 120; a big vendor over a long window can take NVD 30+ seconds) naming the vendor (or mapped to its CPE with match=cpe), counts by severity, average and maximum CVSS score, CVEs per week, top CWE weaknesses and the highest-scored CVEs with score, severity, vector, date and description. - GET/search
/bbc-news-articlesNo price listedBBC News top stories from the public BBC RSS feed (latest items; keyword filter on title/summary). Headlines and summaries only, no full article text. Public feed, no key. - GET/security
/phishtank-checkNo price listedLooks one http or https URL up in the PhishTank phishing database (live checkurl lookup, no key). Returns whether PhishTank has the URL and, if so, its phish id, verification flag and validity. Absence means PhishTank has no record of this exact URL, not that it is safe. - GET/search
/bing-searchNo price listedBing web search results (Bing's public RSS search output, no key): result title, URL and snippet, in Bing's ranking order. Shows the first page of results Bing returns for the query; no paging, no ad or SERP-feature data. - GET/security
/hibp-breach-checkNo price listedLists the data breaches HaveIBeenPwned has recorded for a domain (breach name, breach date, accounts affected, data types exposed, verified flag). It is the public breach catalogue, not a check of individual email addresses (that needs a paid key and is not offered here). - GET/security
/dkim-key-checkerNo price listedReads the DKIM public key published at <selector>._domainkey.<domain>: key type, whether it is revoked (empty p=), decoded key size in bytes and a strength hint (about 1024-bit vs 2048-bit RSA), and basic syntax (v=DKIM1). Follows one CNAME, which large providers use. Does not check a signed message. - GET/security
/barracuda-reputationNo price listedChecks an IPv4 mail-sending address against the Barracuda Reputation Block List (b.barracudacentral.org) through public DNS. Listed addresses return a 127.0.0.x code; unlisted ones return no record. The list is updated continuously, so this is a point-in-time answer. Domain reputation is not covered. - GET/search
/hacker-newsNo price listedHacker News story search through the official HN Search API (Algolia, public, no key): title, article URL, author, points, comment count and discussion link. Returns stories only, most relevant first. - GET/search
/bingx-marketsNo price listedBingX perpetual swap market ticker (public open API, no key): last price, 24h change, high, low, open, base and quote volume and the time of the last candle close for one symbol such as BTC-USDT. Read-only market data; no trading. - GET/security
/mitre-attck-matrixNo price listedLooks up one MITRE ATT&CK technique (e.g. T1059 or T1059.001) on its official public page: its name, the tactic-level summary text and the page title. Reads one page per call; it does not return the whole matrix or a technique's sub-techniques list. - GET/search
/wechat-articlesNo price listedWeChat Official Account (公众号) articles matching a query, from Sogou WeChat search (weixin.sogou.com): title, summary, account name, publish time and link, 10 per page. Links are Sogou redirect links that open the mp.weixin.qq.com article in a browser. Sogou may show a captcha under heavy use; that returns 503. - GET/security
/cors-misconfigNo price listedChecks how a site's home page answers a cross-origin request from a made-up origin: whether it echoes that origin back, sends a wildcard (*), and whether credentials are allowed with it. Echoing an arbitrary origin together with credentials is the risky case. One GET of the home page; it does not test API routes or the null origin. - GET/security
/threatfox-iocsNo price listedSearches abuse.ch ThreatFox for indicators of compromise matching a term (IP, IP:port, domain, URL or file hash): IOC, type, malware family, threat type, confidence, first/last seen, reporter, tags and Malpedia link. Optional exact match and a first-seen window in days. - GET/security
/cymru-asn-lookupNo price listedMaps an IPv4 address to its origin AS number, the BGP prefix that covers it, the country, the registry and the allocation date, using Team Cymru's public IP-to-ASN DNS service. Returns no origin when Cymru has no mapping for the address. - GET/security
/spameatingmonkeyNo price listedChecks an IPv4 mail-sending address against the SpamEatingMonkey DNS blocklist (bl.spameatingmonkey.net) through public DNS. A listed address returns its 127.0.0.x return code; an unlisted one returns no record. Listings change often; this is a point-in-time answer. - GET/security
/dns-caa-recordsNo price listedLists the CAA (Certification Authority Authorization) records published on a domain: which CAs may issue certificates (issue), wildcard certificates (issuewild) and the incident-report address (iodef). Shows the records on the exact name only; CAA is inherited from parent domains when a name has none, which this tool does not walk. - GET/search
/owgr-golf-rankingsNo price listedOfficial World Golf Ranking (OWGR public ranking API, no key): current men's position, player name, country, total points, average points and last week's position for the top players. Current ranking only; no tour or event history. - GET/search
/wsj-articlesNo price listedWSJ World News headlines from the public Dow Jones RSS feed (latest items; keyword filter on title/summary). Headlines and short summaries only; full articles are paywalled and not returned. Public feed, no key. - GET/security
/bgp-prefix-originNo price listedFor an IPv4 prefix (e.g. 8.8.8.0/24): the origin AS seen announcing it now across RIPE RIS peers, its RPKI status for that origin (valid, invalid or unknown), route objects, visibility, and how many more-specific and less-specific prefixes are seen. An 'invalid' RPKI status is a hijack warning sign; it is not proof of a hijack. - GET/security
/ssl-cert-chainNo price listedHTTPS certificate chain and cipher audit for a host (port 443) from Qualys SSL Labs' cached report: grade, number of certificates in the chain, trust store, TLS versions, weak-cipher count, Heartbleed/POODLE/BEAST flags and HSTS. Only reads reports SSL Labs already has, so a host that was never scanned returns a retry error instead of a new scan.
