Multi-Source Lead Enrichment

Enrich business leads with normalized company data, contact scoring, industry classification, and data completeness analysis. Provide leads as JSON from any source — CRM exports, scrapers, spreadsheets, or APIs.

What does Multi-Source Lead Enrichment do?

Multi-Source Lead Enrichment takes raw lead data and produces clean, structured, scored records ready for sales outreach or CRM import. It normalizes messy fields, infers missing information, scores leads by quality, and deduplicates records from multiple sources.

You provide lead data as JSON. The actor analyzes each record, normalizes names/domains/phones/emails, infers industry/seniority/department, calculates a lead score and data completeness percentage, and tags leads for easy filtering.

This actor does not scrape or fetch any websites. All processing is done on data you provide.

Why use Multi-Source Lead Enrichment?

• Source-agnostic — Works with leads from any CRM, scraper, spreadsheet, or API
• Smart deduplication — Merge duplicate leads by domain, email, or company name, keeping the most complete record
• Lead scoring — 0-100 score based on company data, contact quality, seniority, and multi-source signals
• Data normalization — Cleans up domains, phone numbers, company names, email validation, company sizes
• Industry & seniority inference — Automatically classifies leads by industry (20 categories) and seniority level
• Automatic tagging — Tags like hot-lead, decision-maker, has-business-email, multi-source

Use cases

• Sales prospecting — Score and prioritize leads before outreach
• CRM cleanup — Normalize and deduplicate messy lead data from multiple sources
• Lead qualification — Automatically tag hot leads and decision-makers
• Data enrichment pipeline — Enrich leads collected by other scrapers or APIs before importing to your CRM
• Market segmentation — Classify leads by industry, company size, and seniority for targeted campaigns

How deduplication works

When deduplicateBy is set (default: domain), leads sharing the same key are merged:

• Non-null fields from both records are kept (first record wins if both have data)
• Sources are combined and deduplicated
• Scores are recalculated after merge

This is useful when combining lead lists from different sources where the same company or contact may appear multiple times.

How much does it cost?

Multi-Source Lead Enrichment uses pay-per-event pricing:

Event	Price	Description
Actor start	$0.035	Charged once per run
Lead enriched	$0.005	Charged per successfully enriched lead

Example costs:

• 10 leads: $0.035 + (10 x $0.005) = $0.085
• 100 leads: $0.035 + (100 x $0.005) = $0.535
• 1,000 leads: $0.035 + (1,000 x $0.005) = $5.035

No proxy or browser costs — pure data processing.

Using the Apify API

Node.js

import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });

const run = await client.actor('YOUR_ACTOR_ID').call({
    leads: [
        {
            companyName: 'Stripe',
            domain: 'stripe.com',
            contactName: 'Jane Smith',
            contactTitle: 'VP of Engineering',
            email: 'jane@stripe.com',
            source: 'LinkedIn',
        },
    ],
    deduplicateBy: 'domain',
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((lead) => {
    console.log(`${lead.contactName} at ${lead.companyName} — Score: ${lead.leadScore}`);
    console.log(`Tags: ${lead.tags.join(', ')}`);
});

Python

from apify_client import ApifyClient

client = ApifyClient("YOUR_API_TOKEN")

run = client.actor("YOUR_ACTOR_ID").call(run_input={
    "leads": [
        {
            "companyName": "Stripe",
            "domain": "stripe.com",
            "contactName": "Jane Smith",
            "contactTitle": "VP of Engineering",
            "email": "jane@stripe.com",
            "source": "LinkedIn",
        },
    ],
    "deduplicateBy": "domain",
})

for lead in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(f"{lead['contactName']} at {lead['companyName']} — Score: {lead['leadScore']}")
    print(f"Tags: {', '.join(lead['tags'])}")

Integrations

Multi-Source Lead Enrichment can be connected with other tools and services:

• Google Sheets — Export enriched leads directly to a spreadsheet
• Webhooks — Get notified when a run completes
• Zapier / Make — Automate workflows triggered by enriched lead data
• Other Apify actors — Chain with scraping actors to enrich their output before CRM import

Tips and best practices

• The more fields you provide per lead, the higher the lead score and data completeness
• Use deduplicateBy: "domain" when merging leads from multiple sources about the same companies
• Filter results by leadScore >= 80 to focus on hot leads
• The tags array lets you quickly segment leads (e.g., all decision-maker + has-business-email leads)
• Use maxLeads to control costs when processing large batches

Compliance

This actor processes only data that you provide as input. It does not scrape, fetch, or access any third-party websites. You are responsible for ensuring that you have the right to process the lead data you supply.
