## FAQ

### How does it detect a company's tech stack?

DNS Technographics reads public DNS records (MX, TXT verification tokens, SPF includes, CNAMEs) that SaaS tools require, so it finds tools a website scan would miss.

### Which tools can it detect?

DNS Technographics recognizes hundreds of vendors, including Microsoft 365, Google Workspace, HubSpot, Salesforce, Zendesk, Atlassian, Okta and many email and support tools.

### Can I find companies using a specific tool?

Yes. Give DNS Technographics a list of domains and a vendor name such as Zendesk, and it keeps only the companies using that vendor.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/dennydevelops/dns-technographics.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
