Introducing the New LeadGenius API Experience: Real-Time Enrichment, Zero Bottlenecks

No emails. No meetings. No delays.
We just made it radically easier to power your go-to-market engine with bespoke, real-time B2B data.
Today, we're excited to unveil a major upgrade to the LeadGenius API experience — designed specifically for developers, operations teams, and technical marketers who want to get up and running fast. Whether you're enriching stale CRM records, activating new ICP contacts, or integrating contact workflows into your product or RevOps stack, our new self-serve API experience puts custom data directly into your hands.
🧠 What’s New?
We’ve rolled out a fully self-serve flow for accessing the LeadGenius API, testing key endpoints, and getting data flowing — all from our public-facing site with zero need for human interaction.
Here’s what’s changed:
✅ Self-Serve Access to the LeadGenius API
You can now register for a LeadGenius API trial account directly from our website. As soon as you sign up, we send you:
- Your personal API key
- Links to ready-to-go Postman collections
- A walk-through of our documentation
- Instructions for setting your webhook for seamless async delivery
This means you can:
- Start enriching companies and contacts within minutes
- Test our endpoints before committing to integration
- Play with sample code and see real-time responses
🧩 A New Developer Hub & API Page
We’ve launched a dedicated API section on our website that:
- Provides a high-level overview of what our API can do
- Links directly to documentation and Postman samples
- Helps technical users understand key use cases like:
- Company Enrichment
docs.leadgenius.com/#rapid-enrichment-account
- Contact Enrichment
docs.leadgenius.com/#rapid-enrichment-contact
- New Contact Discovery at Target Accounts
docs.leadgenius.com/#rapid-enrichment-get-contacts
- Company Enrichment
Each of these sections includes clear examples and Postman calls so your team can copy, test, and build immediately.
💡 Use Cases That Drive Revenue Ops
You’ll find a guided tour of the three most common use cases:
- Company Enrichment
Plug in a domain, name, or LinkedIn URL → get back firmographics, technographics, account signals, and more. Perfect for CRM enrichment, data audits, and ABM readiness. - Contact Enrichment
Provide a name or contact descriptor → receive detailed profiles including work emails, roles, titles, and verified location. Great for SDR and BDR workflows. - Contact Append (Account-Based Contact Discovery)
Upload an ICP and target company → get back a list of matched contacts. Use the enrichment endpoint to unlock full profiles and power personalized outreach.
🔗 Seamless Onboarding
Every new API trial user receives a Welcome Email with:
- Your API token
- A dashboard link to configure webhooks and access settings
- Direct links to API documentation and Postman environments
We're also tagging and segmenting all self-serve signups to tailor onboarding based on user goals — making it even easier to transition from trial to integration.
💬 Why It Matters
In a world where off-the-shelf data vendors are slow, static, and siloed, LeadGenius is leaning into speed, customization, and automation. This release isn’t just a technical upgrade — it’s a philosophical one. We believe data should work the way your business works, not the other way around.
No more waiting for sales to follow up.
No more vague PDF docs or guessing at API structure.
Just fast, flexible access to world-class data — when and how you need it.
