Audit email authentication for a list of domains: SPF, DKIM (about 40 common selectors), DMARC, MX provider, MTA-STS, TLS-RPT and BIMI, graded A-F with spoofing risk and plain-English fixes. Unlike company_website_enricher (firmographics, tech stack, contacts), this only grades mail security posture from public DNS. Use when you need deliverability or spoofing checks, a security prospect list, or a vendor review. Do not use for website SEO or AI-readiness (use ai_search_seo_audit) or for page-level prompt injection (use hidden_ai_instructions_scanner). Parameters: domains accept bare domains, emails or URLs and are normalized and de-duplicated. DKIM is only confirmed when a selector matches; add dkimSelectors you know are in use, otherwise a missing DKIM may be a false negative. Nonexistent or unresolvable domains are returned with a status and not charged. Returns per item: agentSummary, domain, grade, score (0-100), spoofable, mailProvider, spfRecord, spfAll, spfLookups, dmarcRecord, dmarcPolicy, dmarcReporting, dkimSelectorsFound, mtaSts, tlsRpt, bimi, mxHosts, fixes (prioritized), status.

Behavior: read-only; runs the Apify Actor pandadad0214/email-domain-security-checker (https://apify.com/pandadad0214/email-domain-security-checker) on your own Apify account. Price: $0.002 per domain checked. Runs that find nothing are not charged per result, and spending is capped per call by run_max_charge_usd (default $0.50). run_max_items (default 50) limits items returned and fills maxDomains when you leave it unset, so it also limits what is billed; setting maxDomains higher can bill more than is returned. Most calls finish in 5-15 s for a few inputs; large inputs or crawls can take minutes, so raise run_timeout_secs (max 300) or shrink the input after a timeout error. Returns JSON {actor, count, items}; long text output is trimmed to whole items, with all items in structuredContent.

Audit web pages for classic SEO and for AI-search readiness (ChatGPT, Perplexity, Claude, Google AI Overviews): titles, meta, schema/FAQ markup, author/date signals, blocked AI crawlers, llms.txt and ranked fixes, with an SEO score and an AI-readiness score per page. Unlike website_change_monitor (diffs pages over time) and hidden_ai_instructions_scanner (finds concealed prompt-injection text), this grades how discoverable and citable a page is. Use when you need an on-page SEO/GEO audit or an llms.txt draft. Do not use for change tracking (use website_change_monitor) or security scanning (use hidden_ai_instructions_scanner or email_domain_security_checker). Parameters: crawlInternalLinks multiplies pages: each URL can add up to that many same-site pages, and every page is billed, so maxPages/run_max_items is the real cost cap. generateLlmsTxt drafts one llms.txt per site lacking it at no extra charge. Pages that block our crawler are returned unbilled. Returns per item: agentSummary, url, seoScore, aiReadinessScore, title, metaDescription, h1, wordCount, schemaTypes, faqSchema, aiSearchBotsBlocked, aiTrainingBotsBlocked, llmsTxt, sitemapFound, canonical, noindex, crawlerBlocked, fixes.

Behavior: read-only; runs the Apify Actor pandadad0214/ai-search-seo-audit (https://apify.com/pandadad0214/ai-search-seo-audit) on your own Apify account. Price: $0.004 per page audited. Runs that find nothing are not charged per result, and spending is capped per call by run_max_charge_usd (default $0.50). run_max_items (default 50) limits items returned and fills maxPages when you leave it unset, so it also limits what is billed; setting maxPages higher can bill more than is returned. Most calls finish in 5-15 s for a few inputs; large inputs or crawls can take minutes, so raise run_timeout_secs (max 300) or shrink the input after a timeout error. Returns JSON {actor, count, items}; long text output is trimmed to whole items, with all items in structuredContent.

Check a watch list of web pages against snapshots saved by your previous run and report added and removed text, change percent, price changes and keyword appear/disappear alerts, with an optional webhook when something changes. Unlike ai_search_seo_audit (one-time quality audit) and hidden_ai_instructions_scanner (concealed AI-directed text), this is stateful diffing over time. Use when you need to track competitor pricing, terms, product or careers pages on a schedule. Do not use for a one-off page read or audit (use ai_search_seo_audit), or for pages behind a login. Parameters: the first run per monitorName only saves baselines (status 'baseline saved'); reuse the same monitorName for every later run, and use a new name for a separate watch list. cssSelector, ignorePatterns and ignoreNumbersAndDates cut false alarms from banners, counters and timestamps. Below minChangePercent the old snapshot is kept, so small edits accumulate. onlyReportChanges shrinks output but every page checked is still billed; unreachable pages are free. webhookUrl posts outside the Apify run; only set it if you control that endpoint. Returns per item: agentSummary, url, label, status, changed, changePercent, addedCount, removedCount, addedLines, removedLines, prices, priceChanges, keywordsPresent, keywordsAppeared, keywordsDisappeared, titleBefore, titleAfter, previousCheckAt.

Behavior: read-only; runs the Apify Actor pandadad0214/website-change-monitor (https://apify.com/pandadad0214/website-change-monitor) on your own Apify account. Price: $0.0015 per page checked. Runs that find nothing are not charged per result, and spending is capped per call by run_max_charge_usd (default $0.50). run_max_items (default 50) limits items returned and fills maxPages when you leave it unset, so it also limits what is billed; setting maxPages higher can bill more than is returned. Most calls finish in 5-15 s for a few inputs; large inputs or crawls can take minutes, so raise run_timeout_secs (max 300) or shrink the input after a timeout error. Returns JSON {actor, count, items}; long text output is trimmed to whole items, with all items in structuredContent.

Scan web pages for text hidden from people but read by AI agents (display:none, off-screen, tiny or same-color text, HTML comments, alt/meta/data attributes, zero-width and Unicode tag characters) and classify it as policy notice, manipulation or harmful prompt injection, with location and excerpt. Unlike ai_search_seo_audit (visible SEO and AI-readiness) and website_change_monitor (diffs over time), this is a security check on content an agent is about to read. Use when an agent or workflow will ingest a page and you need to know whether it carries hidden instructions, or when auditing your own site. Do not use for SEO grading (use ai_search_seo_audit) or for email security (use email_domain_security_checker). Parameters: renderJs=true runs a real browser to catch script-injected text (much slower, plus settleSecs per page); off is a fast HTTP read. agentUaDiff adds three fetches per page (GPTBot, ClaudeBot, ChatGPT-User) to detect cloaking. crawlDepth follows same-site links but maxPages always caps the run. Findings are leads for review, not proof of intent. Returns per item: page summaries (type page-summary, url, verdict, findings, categories, topSeverity, techniques, agentSummary) and findings (technique, location, excerpt, category, severity).

Behavior: read-only; runs the Apify Actor pandadad0214/hidden-ai-instructions-scanner (https://apify.com/pandadad0214/hidden-ai-instructions-scanner) on your own Apify account. Price: free (no per-result charge). Runs that find nothing are not charged per result, and spending is capped per call by run_max_charge_usd (default $0.50). run_max_items (default 50) limits items returned and fills maxPages when you leave it unset, so it also limits what is billed; setting maxPages higher can bill more than is returned. Most calls finish in 5-15 s for a few inputs; large inputs or crawls can take minutes, so raise run_timeout_secs (max 300) or shrink the input after a timeout error.
