Domain-scoped email extraction. Useful for lead generation pipelines, contact research, and outreach list enrichment.
Closed to new sign-ups since Oct 1, 2024
The Leads API has no direct modern replacement - for similar workflows, see the email-extractor scraper (any URL → emails) or the google-serp scraper for domain-scoped contact discovery. Existing integrations continue to work, no shutdown is scheduled.
Overview
The Leads API extracts publicly visible email addresses associated with a domain. Useful for lead generation, contact research, and verifying outreach lists.
Endpoint:https://api.crawlbase.com/leads
Quickstart
curl 'https://api.crawlbase.com/leads?token=YOUR_TOKEN&domain=slack.com'Parameters
Your Crawlbase token.
Bare domain (no scheme, no path). Example:
slack.com.Maximum number of emails to return. Defaults to 10. Billing is 1 credit per 10 emails (or fewer) per domain - a
limit=100 call that returns 100 emails consumes 10 credits.Response shape
JSON with discovered email addresses, source URLs where each was found, and contact metadata where available.
Modern equivalent
Two paths:
- For full LinkedIn-style enrichment (titles, companies, profiles): use Crawling API with
scraper=linkedin-profileorscraper=linkedin-company. - For raw email extraction: use
scraper=email-extractoron any page, or fetch the page and run regex over the body. The dedicated endpoint became hard to keep correct as websites evolved their contact-page structures.
