Domain validation
Validate domain ownership and DNS configuration.
This check runs on the server. Input and results are not saved as execution history; hosted allowances apply.
About Domain validation
Check a domain’s public address and TXT records, including an optional expected challenge value.
When to use it
Check whether a DNS challenge has been published.
Domain + expected TXT value → record matchHow to use it
- Enter a domain and optional expected TXT text.
- Inspect its public records and whether the text is present.
Limits & privacy
Public DNS-over-HTTPS queries only. Results are fetched on the server and are not retained as execution history. Lookup sources are the public services queried for these checks, not the domain’s DNS hosting provider. These checks do not change DNS records. A TXT match is informational; this tool does not grant domain ownership or configure hosting.
Use this tool from the API reference or connect through the SDK, CLI, SSH, or MCP. Hosted calls share your plan allowances.
