Sell to companies the week they start spending.
A company that just launched ads has budget, a goal and a team working on growth. One call per domain tells you whether it advertises right now, on which platforms and how many ads it runs.
- Agencies prospecting for clients
- Sales teams selling to marketers
- Data vendors enriching company lists
The problem
Firmographics do not show intent
Headcount and industry say who could buy. They don't say who started spending on growth this month.
Checking ad libraries per lead is slow
Opening six libraries for each of 500 prospects takes days, and the result is stale the week after.
Lists go stale
A company that was not advertising last month may be now. Without a regular recheck you miss the week it starts.
How it works with AdLib
- 01
Check a domain
A yes, no or unknown verdict, plus per platform whether there are current ads, how many and the latest ad date.
curl "https://api.adlibapi.com/v1/domains/acme.com/check" \ -H "X-API-Key: $ADLIB_API_KEY" - 02
Run a whole list as a batch
Send up to 100 domains per job and get a signed webhook when it is done. From Clay, call the same endpoint with an HTTP column; for n8n there is a node.
curl -X POST https://api.adlibapi.com/v1/batch \ -H "X-API-Key: $ADLIB_API_KEY" -H "Content-Type: application/json" \ -d '{"type": "domains", "items": ["acme.com", "globex.com", "initech.com"]}' - 03
Score and route
Rank by platforms and ad count, route companies that just started advertising to the right rep, and recheck monthly to catch new starters.
What it costs
Starter ($29 a month) covers about 8,000 domain checks; Growth ($99) about 40,000.

Questions
- How can I find companies that are running ads right now?
- Send a list of company domains to AdLib's domain check. For each domain it returns whether the company has current ads on Meta, Google, TikTok, LinkedIn, Pinterest and X, how many and the latest ad date.
- Is ad activity a good buying signal?
- For anyone selling to marketing and growth teams it is one of the strongest public signals: a company that launches ads has budget allocated and somebody responsible for results. Combine it with firmographics for scoring.
- Can I use AdLib in Clay?
- Yes. Add an HTTP API column that calls GET /v1/domains/{domain}/check with your key in the X-API-Key header and map the verdict and per-platform counts into columns.
- What does a check cost?
- 3 credits per domain. Checks where no platform could be checked are free.
