# Personalize cold emails with a prospect's hobbies

**Use case:** 

Paste a prospect's LinkedIn URL and get a first line built on something true about them: the marathon they ran, the team they root for, the rescue dog they adopted. Every fact comes with the source URL and the exact quote, so you can check it before you send. No verified personal fact means no charge.

## Input

```json
{
  "linkedinUrls": [
    "https://www.linkedin.com/in/williamhgates/"
  ],
  "maxUrls": 1
}
```

## Output

```json
{
  "fullName": {
    "label": "Full name",
    "format": "string"
  },
  "company": {
    "label": "Company",
    "format": "string"
  },
  "personal_hook": {
    "label": "Personal hook",
    "format": "string"
  },
  "interest_1": {
    "label": "Interest 1",
    "format": "string"
  },
  "interest_2": {
    "label": "Interest 2",
    "format": "string"
  },
  "source_1": {
    "label": "Source URL",
    "format": "string"
  },
  "quote_1": {
    "label": "Quote",
    "format": "string"
  },
  "identityConfidence": {
    "label": "Identity confidence",
    "format": "number"
  },
  "sourceProfileUrl": {
    "label": "LinkedIn URL",
    "format": "string"
  }
}
```

## 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/greg_benbetter/uniqueness-engine.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`).
