Base URLhttps://api.webintel-api.workers.dev/api

• GET/search/wayback-cdx—No price listedInternet Archive Wayback Machine CDX index: archived snapshots of a URL or domain (timestamp, original URL, MIME type, HTTP status, length) with a link to each capture. Public, no key; the index lists captures, not page text.
• GET/search/nyt-articles—No price listedNew York Times home page headlines from the public NYT RSS feed (latest items; keyword filter on title/summary/categories). Headlines and abstracts only. Public feed, no key.
• GET/security/ip-geolocation-asn—No price listedIPv4 or IPv6 address → covering BGP prefix, origin AS number and holder name, whether the prefix is announced, and a coarse country and map point, all from RIPEstat. Location is an estimate (a block-level database), not a street address; the city is often empty.
• GET/search/semafor-articles—No price listedSemafor articles from its public RSS feed (keyword filter on title/summary/categories). Latest items only. Public feed, no key.
• GET/security/blocklist-de—No price listedChecks an IPv4 address against the Blocklist.de 'all' list of IPs reported for attacks such as failed logins, SSH and mail abuse (about 24,000 addresses). A hit means it was reported recently; the list keeps only current reports.
• GET/search/ap-news-articles—No price listedLatest Associated Press (AP News) articles: headline, publisher, publish time and link, newest first, optionally matching search words, from the last 1-30 days. Found through Google News's public RSS index of apnews.com (the site blocks automated clients); links are Google News redirect links to the article. Headlines only, no article text.
• GET/search/hackernews-items—No price listedOne Hacker News item by numeric id from the official HN API (Firebase, public, no key): type, title, author, time, score, comment count, link and plain text. Deleted or unknown ids return 404.
• GET/security/ssh-banner-audit—No price listedFrom Shodan's pre-collected passive scan data: whether TCP port 22 was seen open on an IPv4 address and any OpenSSH version identified in its software (CPE) list. This is passive and may be days old; it is not a live SSH banner grab or algorithm audit.
• GET/security/mta-sts-validator—No price listedChecks MTA-STS for a mail domain: the _mta-sts TXT record (v=STSv1 and id) and the HTTPS policy file (mode enforce, testing or none, the MX patterns and max_age). Reports whether the record and the policy are both present and whether the policy's version is valid. Does not test the mail servers themselves.
• GET/search/prnewswire-press-releases—No price listedPR Newswire health-category press releases from its public RSS feed (keyword filter on title/summary). Latest items only. Public feed, no key.
• GET/security/reverse-dns-ptr—No price listedReverse DNS (PTR) names for an IPv4 address, and forward-confirmed reverse DNS: whether each PTR name resolves back (A record) to the same address. Up to 3 PTR names are checked. Many addresses have no PTR record; that is a normal answer.
• GET/search/unpaywall—No price listedUnpaywall open-access lookup by DOI (free API; it requires a contact e-mail set in UNPAYWALL_EMAIL, not a key): is the paper open access, OA status, best free full-text link, journal and publisher. Returns metadata and links only, not the PDF.
• GET/security/crossdomain-xml-test—No price listedReads a site's public crossdomain.xml (Adobe Flash) and clientaccesspolicy.xml (Silverlight) if they exist, lists the origins they allow, and flags wildcard grants ('*'). Old policies are rarely needed now, so a wildcard here mostly means leftovers; absence is the normal case.
• GET/search/ft-com-articles—No price listedFinancial Times headlines from the public FT RSS feeds: international homepage or any section/topic stream (world, markets, companies, technology, opinion, global-economy, us, uk, climate-capital...). Keyword filter on title/summary. Headlines and standfirsts only; full articles are paywalled and not returned. Public feed, no key.
• GET/search/datacite-metadata—No price listedDataCite DOI search (public REST API, no key): DOI, title, publication year, resource type, publisher, creators and landing page for datasets, software and other research outputs. Metadata only.
• GET/security/email-disposable—No price listedChecks whether an email address's domain (or a domain you give) is on the community disposable and temporary email blocklist (about 9,900 domains). Only the domain is checked, never the mailbox, and a domain missing from the list is not proven to be permanent.
• GET/security/dns-records—No price listedDNS records of a domain (A, AAAA, MX, NS, TXT, CNAME, CAA, SOA) resolved live through the public AdGuard DNS JSON resolver (NextDNS as backup). Shows answers as they resolve now, with TTLs; it does not walk the delegation chain or query the authoritative servers directly.
• GET/search/beehiiv-newsletter—No price listedPost archive of a beehiiv newsletter (by beehiiv subdomain, e.g. superhuman, or the newsletter's own domain if hosted on beehiiv): newsletter name, total posts, and per post title, subtitle, URL, publish time, authors, free/premium audience, tags and reading time, 10 per page, newest first. Optional word filter within the page. Public archive data, no key; post bodies are not returned.
• GET/security/dnssec-validator—No price listedDNSSEC check for a domain: whether a DS record exists at the parent zone (the domain is signed), and whether two public validating resolvers (AdGuard DNS, NextDNS) return its A answer with the AD (authenticated) flag. It reads the resolvers' verdict; it does not validate the signature chain itself.
• GET/search/google-ads—No price listedGoogle Ads Transparency Center: search advertisers by name or domain (verified name, advertiser ID, country, approximate ad count), or list the ads of an advertiser ID or website domain (creative ID, format, first and last shown dates, days shown, preview URL, Transparency Center link), optionally for one country; plus the approximate total number of ads.
• GET/security/spamhaus-zen—No price listedSpamhaus blocklist check through Spamhaus's official Data Query Service: an IPv4 address against ZEN (SBL spam sources, CSS snowshoe, XBL exploited/botnet hosts, DROP hijacked ranges, PBL end-user ranges) or a domain against the Domain Block List (spam, phishing, malware, botnet C&C, abused legitimate domains). Returns listed yes/no, every return code with the list it means, and Spamhaus's lookup link. Point-in-time answer.
• GET/security/tls-alpn-detector—No price listedReports which newer HTTP protocols a site advertises: HTTP/3 (h3) and older draft or HTTP/2 alternatives in its Alt-Svc response header, and the Alt-Svc max-age. This is what the server announces, not a TLS ALPN negotiation: the fetch this tool makes cannot choose the protocol, so a site that negotiates but does not send Alt-Svc will show as not advertised.
• GET/security/open-port-scanner—No price listedLists the TCP ports Shodan has seen open on an IPv4 address, from its pre-collected passive scan data (not a live scan: nothing connects to the address now). The record can be days old, and an address with no record returns known=false, which does not prove the ports are closed.
• GET/search/defector-articles—No price listedDefector articles from its public RSS feed (keyword filter on title/summary/tags). Latest items only; excerpts are as published in the feed. Public feed, no key.
• GET/search/pubmed-article-metadata—No price listedPubMed article metadata by PMID (NCBI E-utilities esummary, public, no key): title, journal, publication date, authors and DOI for up to 20 ids. Summary fields only, no abstracts.
