# Contacts from JavaScript-heavy websites (browser mode)

**Use case:** 

Some websites show their emails and social links only after JavaScript runs, so plain HTTP scrapers return nothing. With browser mode on, sites where the normal crawl found no contacts (or that blocked it) are opened once more in headless Chrome. These sites are billed at the separate browser price and only if contacts are found. Give the run 2048 MB of memory.

## 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/apifry/website-contact-extractor.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`).
