# Qualify a list of B2B prospects by tech stack

**Use case:** 

Paste company domains and get, for each one, its CMS or e-commerce platform, analytics, chat widget, payment tool, email provider and the SaaS it declares in DNS, with evidence for every finding. Filter the prospects whose stack fits your offer. Reads DNS and the home page once, robots.txt respected. Absence of a tool proves nothing.

## 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/lakadev/website-tech-stack-detector.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`).
