What DomScan does
DomScan replaces a stack of separate lookups. Instead of using a WHOIS site, a DNS checker and a security scanner, you call one API. The listing says it can check domain availability, read registry records through WHOIS or RDAP, look up A, AAAA, MX, NS, TXT and CNAME records, inspect certificates and reputation, and verify email authentication.
It also collects page content as HTML, Markdown or text, identifies site technology, follows redirect chains and compares DNS answers to spot configuration changes. A distinctive feature is that uncertain results stay visible when evidence is blocked or incomplete, rather than being guessed. The founder says it started as an MCP for checking domain availability while brainstorming names.

The pricing grid lists all public endpoints (domain, DNS, WHOIS, brand, website, email, IP and security intelligence), MCP integration, and the groups Web Data, DNS and Infrastructure, Security and Trust, Identity and Verification, and Monitoring and Automation. The text we captured did not show per-tier differences beyond credits.
Cost per credit

| Tier 4 | 250,000 | $2.00 |
The vendor says each operation has a published credit cost, but we did not capture the rate card. Check it before choosing a tier, because it decides how many lookups your monthly credits actually cover.
What buyers say
There are only 6 reviews, so this is early feedback. One buyer says the AI set everything up through the MCP and that they now monitor a single domain they would buy instantly if it became available. That is one use case, not a measured result.
What to check before you buy
- Credit rates. Find the published credit cost per operation and estimate your monthly volume.
- Data quality. WHOIS and valuation estimates can be incomplete or privacy-masked. Treat valuations as rough signals.
- Technical fit. It is an API and MCP tool. You need to be comfortable with API calls or an AI client.
- Company. Founded June 2025 in Spain, 1 to 10 staff, bootstrapped. Lifetime access depends on a very small company continuing.
- Alternatives. The listing names DataForSEO and ScraperAPI. Compare with the specific endpoints you need.
- Legitimate use. Scraping and lookups should follow the target sites’ terms and local law.
Who it suits
AppSumo lists developers, IT and security agencies and data analysts as the best fit. It suits people who vet domains often, build monitoring workflows or want an AI assistant to check domain facts directly. If you only look up a domain now and then, a free WHOIS or DNS site may be enough.

Bottom line
DomScan is a developer-oriented domain research API with MCP support, and the $39 tier is a cheap way to test it within the 60-day refund window. Check the credit rate card and your expected volume first, since a very young, one-person-scale vendor is the main risk. See the current DomScan deal on AppSumo.
