Robots.txt compliance check for polite crawlers and AI agents (GPTBot, ClaudeBot, ...). Pass a page URL and optionally your crawler's product token; returns whether the URL may be fetched, the winning Allow/Disallow rule, crawl-delay and sitemap URLs. Full RFC 9309 matching: wildcards, $ anchors, longest-match, merged groups. A 4xx robots.txt allows all; 5xx or unreachable hosts report disallowed. Cached per host for 1 hour.

Domain availability and expiry intelligence via RDAP, the WHOIS successor. Queries the authoritative registry for any RDAP-enabled TLD: free domains return registered:false, taken ones return registrar, creation and expiry dates, nameservers and EPP status codes. TLDs without RDAP coverage return supported:false. Built for agents that buy, monitor or vet domains.

Validate a US ABA routing number before initiating a transfer: the 3-7-1 checksum, the public structure rules (9 digits; assigned prefixes 00-12 primary, 21-32 thrift, 61-72 electronic, 80 traveler's cheque) and the implied Federal Reserve district. Checksum and structure only — no bank-name directory (the Fed's routing directory is redistribution-restricted) and no proof the number is currently assigned. Purely local, instant.

TLD info / top-level domain registry lookup / ccTLD vs gTLD / TLD introduction year / new gTLD registry. For any top-level domain, returns the registry operator, type (gTLD / ccTLD / sTLD), country (for ccTLDs), introduction year, and notes. In-handler dictionary covers ~80 of the most common TLDs; falls back to a structural guess for unrecognized TLDs.

WHOIS / RDAP / domain age / domain expiry / registrar finder / nameserver lookup / DNSSEC check / TLD registration record / brand-protection triage. Short alias of whois-lookup.

Optionally appends a crt.sh certificate-transparency summary.

DNS lookup / DNS resolver / dig replacement / nslookup API / DoH proxy / authoritative-record fetch / MX checker / SPF + DMARC TXT inspector / CAA + DNSSEC inspector / nameserver finder / CDN-routing detector.
