Deep Enrichment (Subdomains) 🔎


Tired of tools that only see the marketing homepage? 
Deep Enrichment looks beyond www. or @ apex  scanning key subdomains and merging everything into a clean company-level stack.


The story
I demoed Techlens to a friend let's call him Jojo

jojo - “Cool, like Wappalyzer?”

me - “Kinda.”

jojo - “Then it sucks.”

me  - “😳 Why?”

jojo - “Every Ruby on Rails company shows up as Webflow or Wordpress .”

me - “You’re checking the marketing site, not the app.”

jojo - “I want Webflow AND Ruby on Rails.”

me - “Got it. You want a deeper analysis .”

jojo - “Exactly.”

me - “Okay then… let’s ship it.”


What it does
  • Crawls beyond the homepage

  • Detects tech across hosts/DNS

  • Merges detections into a single Domain/Company stack (no duplicates, sensible weighting).

  • Result: “Webflow + Ruby on Rails” instead of just “Webflow”.

How to use it?
It's so cool and game changer that it"s built in !

Why it matters
Better lists. Fewer false negatives.

Use it for prospecting by stack, ATS/CRM detection, and cleaner enrichment.

What’s next
  • Webhooks
  • A UI would be nice 😅
  • MCP server
  • List builder
  • Job signals (gather tech stack from job posts)

⚡ New: Bulk Lookup API


Need to scan a lot of domains at once?
The Bulk Lookup endpoint is here — run technology detection on up to 100 domains per request.

Why I added it
I need a faster way to enrich lists.
Instead of looping through the single-domain endpoint, you can now post a batch and let Techlens handle the heavy lifting.

How it works
  1. POST /api/v1/bulk/lookup with a JSON array of up to 100 domains.
  2. You’ll receive a job id right away.
  3. Poll GET /api/v1/bulk/lookup/{id} to retrieve the results when they’re ready.

Webhooks are on the roadmap — for now, polling is the way.



Example

# Submit the batch
curl -X POST https://api.techlens.io/api/v1/bulk/lookup \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domains": ["example.com", "acme.io", "shop.co"]}'

# Later, fetch results
curl https://api.techlens.io/api/v1/bulk/lookup/abcd1234 \
  -H "Authorization: Bearer YOUR_API_KEY"


What’s next
  • Webhook callbacks for completed jobs
  • Larger batches for enterprise plans
  • CSV upload from the dashboard

Introducing the Techlens API (v1)🔥


Today I  am shipping the first public release of the Techlens API!
Techlens scans the real technology stack behind any company,  so you can build accurate lists, enrich leads, or power your own apps.


Why I built it
My first use case was the following:
I need to prospect all the companies in the world using Ruby on Rails.
And you what it's crazy difficult and expensive.
Existing tools like Wappalyzer or BuiltWith focus mainly on Enterprise companies.
Their pricing is not frendly at all because they do too much.

I believe in pure player that do 1 feature super well. Not 10 features, just one.
I just want an accurate list that I can enrich in Clay, Apollo or Hunter.io 

Now it's possible.

How to get started
  1. Create an account on Techlens
  2.  Generate an API key from your dashboard
  3. Read the docs → API Documentation
  4. Start scanning domains and get structured JSON with detected technologies.

What’s next
We’ll keep expanding the catalog (currently ~3,800 technologies) and improve detection depth.

If you build something cool with the API, let me know .
