Get all major DNS record types for a domain in a single call with IPv6 parity, TXT classification, wildcard probe, and warning signals. (costs 2 credits)

get_all_dns_records

Get the lookup-driven DNS observation log for a domain. Returns day-level added and removed events from prior successful DomScan DNS lookups, not internet-wide passive DNS history. (costs 3 credits)

dns_history

Lookup DNS records for a domain. Returns A, AAAA, MX, TXT, NS, CNAME, and other record types plus TXT classification and additive warnings. (costs 1 credit)

dns_lookup

Compare answers from DomScan's configured public recursive resolvers. This is a resolver comparison, not a geographic or worldwide propagation measurement. (costs 2 credits)

dns_propagation

Analyze DNS security configuration including SPF, DKIM, DMARC, DNSSEC, CAA, MTA-STS, TLS-RPT, resolver latency, and AXFR exposure. The classification field gives present, absent or unknown (with a reason) plus evidence; never treat unknown as absent. (costs 3 credits)

dns_security

Check if a domain name is available across multiple TLDs. The primary HTTP format uses "name" plus "tlds". The "name" parameter is the domain label WITHOUT the TLD (e.g., "google" not "google.com"). The "tlds" parameter is a comma-separated string of TLD extensions (up to 50). The classification field gives present, absent or unknown (with a reason) plus evidence; never treat unknown as absent. (costs 1 credit)

get_status

Compare multiple domains side-by-side. Returns availability, valuation, brand score, and recommendations. (costs 3 credits)

compare_domains

Run comprehensive health checks on a domain including DNS, SSL, live TLS grading, HTTP version support, HSTS posture, SMTP TLS reachability, and MX FCrDNS. (costs 3 credits)

domain_health

Get domain lifecycle information including registration date, expiration date, domain age, days until expiry, and current lifecycle phase. (costs 2 credits)

domain_lifecycle

Aggregate DNS, RDAP registration, health, reputation, and popularity observations. Unknown values are null, and component_freshness explains degraded or cached evidence. (costs 5 credits)

domain_overview

Get a domain's current Tranco rank and bucket with source date, cache state, checked timestamp, and optional lookup-driven history. Unknown upstream results remain distinct from unranked domains. (costs 2 credits)

domain_popularity

Read prior Tranco observations recorded by DomScan lookups. This is a lookup-driven history, not a complete daily rank series. (costs 1 credit)

get_domain_popularity_history

Get normalized RDAP registration data: registrar, dates, nameservers, DNSSEC status. (costs 3 credits)

get_domain_profile

Calculate a comprehensive reputation score for a domain based on DNS security, SSL, web presence, blacklist, parking, and email factors, including confidence metadata. (costs 3 credits)

domain_reputation

Calculate an overall domain quality score based on multiple factors. (costs 1 credit)

get_domain_score

Rate a domain security posture 0-100 with grade A-F from TLS, security headers, SPF/DMARC, DNSSEC/CAA, blocklists and security.txt. Unknown checks are excluded and reported; null score when nothing could be measured. (costs 5 credits)

security_rating

Estimate the market value of a domain name based on length, keywords, TLD, brandability, and market factors. (costs 2 credits)

domain_valuation

Check email authentication configuration (SPF, DKIM, DMARC) plus MTA-STS, TLS-RPT, and recursive SPF behavior for a domain. The classification field gives present, absent or unknown (with a reason) plus evidence; never treat unknown as absent. (costs 3 credits)

email_security

Merge normalized RDAP registration data with available traditional WHOIS enrichment for a domain. (costs 3 credits)

enhanced_whois_lookup

Detect hosting provider, CDN, WAF, DNS provider, and email infrastructure for a domain. (costs 3 credits)

hosting_detection

Validate the hreflang annotations of a public page (HTML and HTTP Link header): language and region codes, x-default, self reference, absolute URLs and conflicts, then confirm return links on up to 20 alternate pages. Unknown alternates are never counted as missing return links. (3 credits.)

hreflang_audit

Analyse an internationalized domain name: Unicode and punycode forms, per-label scripts, mixed-script and invisible-character detection, lookalike characters, a confusable skeleton and a homograph risk level. Uses a curated subset of Unicode confusables. (costs 1 credit)

idn_analysis

Compare the raw HTML of a public page with its JavaScript-rendered version and list the SEO signals that only appear or change after rendering (title, meta description, canonical, robots, H1, word count, links, structured data, hreflang, language), with an impact level and an overall JavaScript dependence of none, low, medium or high. (7 credits.)

render_diff

Measure keyword frequency and density in the visible text of a public page: top one, two and three word phrases with counts and density, stopwords removed for supported languages, and optional target keywords checked for placement in the title, meta description, H1, headings, URL and first 100 words. (2 credits, 6 rendered.)

keyword_density

Audit one public page for on-page SEO: title, meta description, canonical, robots, headings, word count, links, images, Open Graph, structured data types and mixed content, with 29 pass, warn or fail checks and a 0-100 score. Set render=true to audit the page after JavaScript runs. status unknown means the page could not be read and is never a passing result. (2 credits, 6 rendered.)

onpage_audit

List the links on a public page with anchor text, rel attributes and internal or external type. Set check=true to test up to 25 unique targets for broken links: only an exact 404, 410 or a host that does not exist is broken, and blocked, challenged or failed checks are unknown, never broken. Set render=true (without check) for links added by JavaScript. (2 credits, 6 rendered or checked.)

page_links

Check if a domain is parked, showing placeholder/ad pages, or listed for sale on aftermarket platforms like Sedo, Afternic, Dan.com, etc. The classification field gives present, absent or unknown (with a reason) plus evidence; never treat unknown as absent. (costs 2 credits)

parking_detection

Calculate how vulnerable a domain is to typosquatting attacks. Returns a protection score and recommendations. (costs 1 credit)

protection_score

Fast health check with essential metrics only. (costs 1 credit)

get_quick_health

Fetch and parse a site robots.txt (RFC 9309): crawler groups and rules, declared sitemaps, an allow or disallow verdict for a user agent and path, and root access for 14 AI crawlers such as GPTBot and ClaudeBot. Failed or blocked fetches return unknown, never allowed. The classification field gives present, absent or unknown (with a reason) plus evidence; never treat unknown as absent. (costs 1 credit)

robots_txt

Test URLs (max 100) against user agents (max 10) with a pasted robots_txt or the live file of url. Returns allowed, the deciding rule and line, and syntax issues. unknown is never allowed. (costs 1 credit)
