The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

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 Propagation Checker Check A, AAAA, CNAME, MX, TXT, and NS propagation across major public resolvers. This actor helps agencies, SEOs, and developers confirm whether a DNS change has actually spread, how far it has spread, and which resolvers still disagree. ### Why use this actor Most DNS tools show a raw lookup. This actor is built for rollout validation. - Queries a curated set of major public resolvers - Supports A, AAAA, CNAME, MX, TXT, and NS records - Compares resolver answers to an optional expected value - Returns a propagation percentage and mismatch summary - Flags timeouts separately from actual mismatches - Adds friendly TTL and retry guidance for humans and automations ### Best use cases - DNS cutovers during site migrations - Verifying Google Search Console, DMARC, DKIM, SPF, or domain ownership TXT records - Checking MX changes after email migrations - Confirming nameserver and CNAME updates before launch - Troubleshooting slow or partial DNS propagation - Feeding DNS validation into SEO or DevOps workflows ### Input #### Minimal example ```json { "domain": "example.com", "recordType": "A" } ```` #### Expected-value validation example ```json { "domain": "_dmarc.example.com", "recordType": "TXT", "expectedValue": "v=DMARC1; p=none; rua=mailto:dmarc@example.com", "retryWaitSeconds": 5 } ``` #### Optional nameserver comparison example ```json { "domain": "www.example.com", "recordType": "CNAME", "expectedValue": "proxy.example.net", "nameserverOverride": "1.1.1.1", "retryWaitSeconds": 3 } ``` ### Output Each run returns one result object with rollout-friendly fields plus per-resolver detail. ```json { "domain": "example.com", "recordType": "A", "expectedValue": "93.184.216.34", "normalizedExpectedValue": "93.184.216.34", "nameserverOverride": null, "retryWaitSeconds": 2, "propagationPercentage": 75, "matchesExpectedValue": false, "matchingResolvers": 6, "respondingResolvers": 8, "dominantValues": [], "successfulResolvers": 8, "failedResolvers": 0, "timeoutResolvers": 0, "likelyTtlNote": "2 responding resolvers still differ from the expected value. This often means caches are still expiring. Retry after 2s or after the record TTL window.", "summary": "75% of responding resolvers matched expected value 93.184.216.34 for A example.com. (6/8 responding). 2 responding resolvers still differ from the expected value.", "resolverResults": [ { "resolverId": "cloudflare-us-east", "provider": "Cloudflare", "region": "us-east", "ip": "1.1.1.1", "status": "ok", "normalizedValues": ["93.184.216.34"], "rawValue": ["93.184.216.34"], "normalizedExpectedValue": "93.184.216.34", "matchesExpectedValue": true, "error": null } ] } ``` ### Pricing Recommended launch pricing is intentionally simple: - Monthly subscription: $9 - Included usage: 10,000 results per month - Overage: $0.40 per additional 1,000 results That keeps the actor easy to try for agencies and technical users while still leaving room to tune pricing after real usage data arrives. See `PRICING.md` for the full store-facing recommendation. ### Example assets included in this repo - `test-data/example-input-a.json` - `test-data/example-input-txt.json` - `test-data/example-output-a.json` - `test-data/example-output-txt.json` - `screenshots/dns-propagation-checker-input.png` - `screenshots/dns-propagation-checker-output.png` ### Local development ```bash npm install npm run health npm run test:local ``` ### Positioning notes Primary audience is SEO and migration workflows. Secondary audience is DevOps and monitoring teams that need resolver-by-resolver confirmation after DNS changes. ### Author Built by [Janice / literal\_jacktree](https://apify.com/literal_jacktree). # Actor input Schema ## `domain` (type: `string`): Domain or hostname to query, for example example.com or \_dmarc.example.com. ## `recordType` (type: `string`): Supported v1 types: A, AAAA, CNAME, MX, TXT, NS. ## `expectedValue` (type: `string`): Optional expected value to compare against normalized resolver responses. ## `nameserverOverride` (type: `string`): Optional authoritative nameserver to compare against, for example ns1.example-dns.com. ## `retryWaitSeconds` (type: `integer`): Optional wait between retry attempts per resolver. ## Actor input object example ```json { "recordType": "A", "retryWaitSeconds": 2 } ``` # API You can run this Actor programmatically using our API.
