All projects on Base 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

DNS + WHOIS/RDAP + TLS composite for one domain. Settles only if ≥1 facet non-empty; else charged:false. Reuses dns-lookup / whois-rdap / ssl-cert-check helpers.

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

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.

Service: DNS Record & Whois Lookup (https://dns-lookup.x402.paysponge.com/)

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.
