Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## DNS + Email + Cloud Footprint Profiler Given a list of domains, returns a rich technographic profile based on public DNS records. Pure DNS over HTTPS (Google + Cloudflare resolvers), no scraping, no auth, fast and accurate. ### What it returns - **MX provider**: Google Workspace, Microsoft 365, Proofpoint, Mimecast, Cisco, Zoho, Fastmail, ProtonMail, self-hosted, etc. - **SPF status**: record present, syntactically valid, all-mechanism strictness. - **DKIM signals**: common selector probes (google, k1, selector1, dkim). - **DMARC policy**: none, quarantine, reject, percentage. - **Nameserver host**: Cloudflare, Route53, GoDaddy, Namecheap, Dynadot, etc. - **CDN / proxy**: Cloudflare, Akamai, Fastly, CloudFront, Sucuri (from CNAME / IP range). - **Hosting**: AWS, GCP, Azure, DigitalOcean, Hetzner, OVH (from PTR / IP block). - **SaaS signals from TXT verification records**: Atlassian, Salesforce, HubSpot, Stripe, Adobe, Zoom, Webex, AWS SES, SendGrid, Postmark, Mailgun, Klaviyo, Intercom, Zendesk, Notion, Linear, GitHub Pages. - **Domain age hint**: from registrar TTL signals (best-effort, since WHOIS isn't queried). ### Why use this - **Sales targeting**: identify "lives on Microsoft 365" or "uses SendGrid" prospects in bulk. - **Security**: surface domains missing SPF/DMARC, easy phishing targets. - **Migration teams**: audit a portfolio's current email + DNS posture before consolidation. - **Investors / analysts**: triangulate vendor stack across a target list. ### Input ```json { "domains": ["airbnb.com", "stripe.com", "github.com"] } ```` ### Pricing - **US$0.01 per domain.** Pay per domain checked. - Preview mode runs the first domain free. ### Output ```json { "domain": "stripe.com", "mx_provider": "Google Workspace", "mx_records": ["aspmx.l.google.com", "alt1.aspmx.l.google.com"], "spf_pass": true, "spf_record": "v=spf1 include:_spf.google.com ~all", "dmarc_policy": "reject", "dmarc_percent": 100, "dkim_selectors_found": ["google"], "ns_provider": "Cloudflare", "name_servers": ["matt.ns.cloudflare.com", "olga.ns.cloudflare.com"], "cdn_provider": "Cloudflare", "hosting_provider": "AWS", "saas_signals": ["AWS SES", "Atlassian", "SendGrid", "Stripe verification"], "checked_at": "2026-05-31T09:00:00Z" } ``` ### Pairs well with - [Shopify Store Detector](https://apify.com/fetchcraft/shopify-store-detector) and [WordPress Stack Detector](https://apify.com/fetchcraft/wordpress-stack-detector): pair DNS-level signals with web-stack technographics for the full picture. - [Email Finder & Verifier](https://apify.com/fetchcraft/email-finder-verifier): confirm MX/email vendor here before running enrichment. - [SaaS Spend Scanner](https://apify.com/fetchcraft/saas-spend-scanner): use DNS TXT signals as a vendor-list seed for the spend scanner. - [AI Sales Personalizer](https://apify.com/fetchcraft/ai-sales-personalizer): feed exact vendor stack into outbound copy that references the prospect's actual tools. - [ATS Job Aggregator](https://apify.com/fetchcraft/ats-job-aggregator): combine hiring-signal with vendor-stack for trigger-event outbound. Deep-dive landing page: https://ai-sales-personalizer.vercel.app/scrapers/dns-email-footprint ### Limitations - DoH resolvers can occasionally return SERVFAIL on misconfigured domains. The actor retries once via the alternate resolver. - DKIM detection is selector-probe based (the standard 8 selectors). Custom selectors won't appear in `dkim_selectors_found` but the record may still exist. ### Integrations This actor works out of the box with every Apify-supported integration: - **API**: call via Apify API or any official SDK (Python, JavaScript, PHP, .NET). Returns a clean dataset URL. - **Schedule**: set a daily, weekly, or custom cron cadence in Apify Console. Combine with `notification` for fresh feeds. - **Webhooks**: wire `ACTOR.RUN.SUCCEEDED` to Slack, Discord, Zapier, Make, n8n, Pipedream, or any HTTPS endpoint. - **MCP**: this actor is discoverable through Apify's hosted MCP server at `mcp.apify.com` for Claude, Cursor, Cline, Windsurf, and other MCP clients. - **n8n / Make / Zapier**: native HTTP-Request integration. Trigger the actor on schedule, pipe results to Google Sheets, Airtable, your CRM, or any database. ### Try it free Every Apify user gets **$5/month in free platform credits** (around 250 events at this actor's per-event price).
