Reads a site's public crossdomain.xml (Adobe Flash) and clientaccesspolicy.xml (Silverlight) if they exist, lists the origins they allow, and flags wildcard grants ('*').

Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Lists 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).

Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Asks two independent public DNS resolvers (AdGuard DNS and NextDNS) for the same name and record type right now and reports whether they agree, with each answer set and its lowest TTL.

Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

DNS records of a domain (A, AAAA, MX, NS, TXT, CNAME, CAA, SOA) resolved live through the public AdGuard DNS JSON resolver (NextDNS as backup).

Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

DNSSEC 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

For a brand domain, generates up to 24 lookalike names (letter omission, doubling and swapping, plus .co/.net/.org/.io swaps) and checks which ones have name servers in DNS right now. Registered-looking names are listed with their name servers. A lookalike with no name servers may still be registered without DNS, and this is not a trademark or phishing verdict. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks whether an email address's domain (or a domain you give) is on the community disposable and temporary email blocklist (about 9,900 domains).

Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Lists the data breaches HaveIBeenPwned has recorded for a domain (breach name, breach date, accounts affected, data types exposed, verified flag).

Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

IPv4 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.

Looks up a file hash (SHA-256, SHA-1 or MD5) in abuse.ch MalwareBazaar: whether the sample is known, its other hashes, file name, type, size, signature (malware family), first/last seen, reporter, origin country, delivery method, tags, download count and code-signing info. Metadata only; the sample itself is never downloaded. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Looks 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

For a mail domain: lists up to 3 MX hosts with their IPv4 addresses and, from Shodan's pre-collected passive scan data, which SMTP ports (25, 465, 587) were seen open on each address. Passive and possibly old; no SMTP conversation, banner, STARTTLS or certificate test is made. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Reports whether Shodan's pre-collected passive scan data shows NTP (port 123) seen open on an IPv4 address. Passive and possibly old; the monlist amplification check itself is not run, so this cannot say whether monlist is enabled. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Lists 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Reports whether Shodan's pre-collected passive scan data shows TCP port 53 (DNS) open on an IPv4 address. It is a passive port fact only: it does not send a query, so it cannot say whether the server answers recursively for outside names. Absence means not seen, not closed. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Looks 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks Shodan's passive scan records for TCP port 3389 (RDP) on an IPv4 address. Says whether RDP was seen open (not a live test, and the record can be days old). An address with no Shodan record returns seen=false with known=false; that is not proof the port is closed. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Reads a site's Referrer-Policy header and its <meta name=referrer> tag from the home page, works out the policy a browser would apply, and rates how much of the URL it sends to other sites (strict, moderate or leaky). One GET; links on other pages can set their own policy. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Reverse 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Reads a site's public robots.txt (crawl rules, sitemaps, AI-crawler rules) and security.txt (RFC 9116: contact, expiry, policy), and says whether security.txt is present, current or expired. Missing files are reported as absent, not as errors. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks the live HTTP response headers of a site's home page (one GET, https) for Content-Security-Policy, Strict-Transport-Security, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy and Cross-Origin-Opener-Policy. Returns present/missing headers with their values and a score out of 7. It does not judge the quality of the values. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Shodan 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks Shodan's passive scan records for TCP port 445 (SMB) on an IPv4 address. Says whether SMB was seen open and when the record was last refreshed by the host data (not a live test). An address with no Shodan record returns seen=false with known=false; that is not proof the port is closed. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Reports whether Shodan's pre-collected passive scan data shows SNMP (UDP port 161) seen open on an IPv4 address. Passive and possibly old; no community string is tried, so default or public community access is not tested. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Spamhaus 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

From 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

HTTPS 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks a certificate SHA-1 fingerprint (40 hex characters) against the abuse.ch SSL Blacklist of certificates seen on malware botnet C2 servers. A hit returns the date added and the malware reason from the list. Only certificates this list tracks are covered. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

For a subdomain: finds its CNAME, matches the target against the public can-i-take-over-xyz fingerprint list (services such as GitHub Pages, S3, Azure, WordPress), checks whether the target still resolves, and fetches the subdomain once to look for the service's 'unclaimed' page text. Verdicts are evidence, not proof; the list is community-maintained. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks a domain against SURBL's multi-list (multi.surbl.org): whether it appears in spam or phishing URI lists. Listed domains return a 127.0.0.x code. Not listed means not in SURBL's current lists, not that the domain is safe. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Cisco Talos reputation for an IPv4 address: threat level (favorable, neutral, poor, untrusted), web reputation score, forward/reverse DNS match, hostname, owner, location, email volume magnitude (daily, monthly and last 30 days), the /24 network's average magnitude and how many neighbouring addresses in that /24 Talos rates untrusted, poor, neutral or favorable. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Searches 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Reports 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

TLS versions a host accepts (SSL 3, TLS 1.0 and 1.1 flagged as deprecated) and its cipher-suite strength from Qualys SSL Labs' cached report: suite count per protocol, weak suites (RC4, 3DES, NULL, EXPORT, DES, anonymous), and whether forward secrecy is offered. Reads existing reports only; a host that was never scanned returns a retry error. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks an IPv4 address against the Tor Project's bulk exit list (about 1,200 active exit IPs). If it is an exit, adds the relays for that address from Onionoo: nickname, flags, country, first and last seen. Only exit IPs are on the list; a relay's other IPs are not checked. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Checks whether a host (domain or IP) is known to abuse.ch URLhaus as a malware distribution host: first seen, number of malware URLs, Spamhaus DBL / SURBL status and the latest URLs with status (online/offline), threat type, tags, reporter and URLhaus reference.

Checks 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. Price: $0.002 in USDC per successful call, paid with x402 (Base, Solana or Arc); failed calls are not charged.

Domain registration facts via RDAP (IANA bootstrap, then the registry's own server): registration, last change and expiry dates, days left, registrar name, status flags, nameservers and DNSSEC delegation flag.
