Node.js Website Email Extractor

Extract every public email address behind any website, domain, or company in Node.js — name, job title, department, verification status, and the organization's metadata. Powered by the Tomba Domain Search API.

A single, dependency-light Node.js file that turns a domain into a full contact list: every person behind the company, with their position, department, seniority, LinkedIn, country, and a verification status — plus the organization's industry, size, location, and email pattern. One domain in, a clean list out.

node index.js stripe.com

Why this one

Most "email extractors" scrape a single page and give you unverified guesses. This Node.js tool queries Tomba's domain search index, so you get the whole company — already de-duplicated, scored, and verified.

• Three ways in — by website (stripe.com, full URLs are normalized), by bare domain, or by company name (--company "Stripe").
• Full detail — name, position, department, seniority, type (personal/generic), 0–100 score, verification status, LinkedIn, Twitter, phone presence, country.
• Org metadata — industry, size, founding year, location, social links, revenue band, detected email pattern.
• Filters — --type personal|generic, --department executive|sales|it|finance|…, --country US.
• Pagination — --limit 5|10|50|100, --page N.
• Pipe-friendly — positional args or stdin; JSON (default) or CSV to stdout, logs to stderr.
• .env autoload — walks up to the nearest .env; an exported TOMBA_KEY always wins.

HTTP uses Node's built-in fetch (zero dependencies) — so there's nothing extra to install beyond Node.js 18+.

Quickstart

git clone https://github.com/tomba-io/website-email-extractor-nodejs.git

Run it

# by website / domain
node index.js stripe.com

# by company name when you don't have the domain
node index.js --company "Stripe"

# only decision-makers, as CSV
node index.js stripe.com --type personal --department executive --csv

# a whole list on stdin
cat examples/domains.txt | node index.js

Output

A top-level JSON array, one object per target — { query, organization, emails[], meta }. Use --csv for one row per email. See sample_output.json for a real response.

The one API call, raw

curl -sG 'https://api.tomba.io/v1/domain-search' \
     --data-urlencode 'domain=stripe.com' \
     --data-urlencode 'limit=10' \
     -H "X-Tomba-Key: $TOMBA_KEY" \
     -H "X-Tomba-Secret: $TOMBA_SECRET" | jq .

The examples/curl/ directory has one runnable script per feature (search by domain, by company, filter by type/department, paginate) with a real captured response next to each.
