All projects matching “dns lookup”

Geo-located DNS resolution — resolve hostnames from specific countries to see how CDNs, geo-blocking, and DNS-based routing differ by region.

Liveness/latency pre-flight for a URL: is it up, HTTP status and class, response latency in ms, whether it redirects (and where), content-type and server.

Send up to 10 domain names and get back every DNS record type (A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA) plus the full WHOIS registration profile (registrar, dates, contacts, status, nameservers) for each one. URLs are accepted and automatically stripped down to the bare domain. Duplicate domains are quietly removed before processing. Results come back as one flat row per d

Email authentication check (SPF, DKIM, DMARC): Check a domain's email authentication and spoofing risk from public DNS: MX and mail provider, SPF (record, all-qualifier, DNS lookup count vs the 10 limit), DMARC policy/pct/rua, DKIM at 30 common selectors, MTA-STS, TLS-RPT, BIMI. Returns grade, spoof

Parse a pasted SPF record without DNS (RFC 7208): mechanisms with qualifiers and values, modifiers, syntax errors, the all policy and the number of terms that need DNS lookups, with coded findings such as +all, ptr and over ten lookups. Use when an agent must check an SPF record before publishing it. Input: {"record": "v=spf1 mx include:_spf.example.com ~all"}.

Lightweight utility API for agents and operators: DNS lookups, RDAP/WHOIS domain data, HTTP probes, page metadata extraction, cryptographic hashing, JSON validation, scheduled webhooks, and exotic endpoints (Base transaction decode, ENS resolve, USGS earthquakes, cron next-run, TLS certificate report). No shell access; outbound URL tools enforce SSRF protections.

Email address verification for AI agents: RFC 5322 syntax check, live MX/A DNS lookup, disposable-domain detection, role-address and free-mail-provider flags, typo suggestions (gmial.com -> gmail.com), normalized form and a low/medium/high risk score. One address or up to 20 per request, same price. No mailbox probing.

DNS lookup: A/AAAA/MX/TXT/NS/CNAME/SOA/CAA, SPF and DMARC presence

DNS lookup API for agents at $0.01 USDC. Call when you need A/AAAA/CNAME/MX/TXT/NS for domain routing, email delivery, or infra checks without running a recursive resolver. Returns structured records via x402—no API key, no subscription.

DNS TXT record lookup — a domain's TXT records as a clean JSON list: SPF, DKIM and DMARC policy strings plus site-verification and domain-ownership tokens, for email-authentication and domain-verification checks.

InboxGuards Email Test: Email security fix plan: the exact SPF, DKIM and DMARC records to publish, with steps for your DNS host. Reads the domain's live MX, NS, SPF, DKIM and DMARC records, detects the mailbox provider and DNS host, and returns the exact records to publish in order (create / replace / keep, name, value, why): one merged SPF within the 10-lookup limit, DKIM records or the provider

Assess how trustworthy a domain is using authoritative live signals, not just its spelling. Fuses RDAP registration data (domain age — the single strongest phishing signal — plus registrar, expiry and registry status flags), DNS resolvability (A/AAAA), MX presence and DNSSEC into a 0-100 risk score with a verdict (low/medium/high) and the exact reasons. Pairs with `urltrust` (lexical) for a comple

Reverse-resolve an IPv4 or IPv6 address to its PTR hostname(s). No PTR record returns an empty list. This is reverse DNS (PTR) — not ENS or onchain name resolution.
