Request an integrationAn API to automate everything
Embed Listar enrichment directly into your products, your workflows or your scripts. A simple REST API, JSON responses, key-based authentication.
REST and JSON
Clear endpoints, structured responses. If you know how to call an API, you know how to use Listar.
Key-based authentication
Generate your API key from your account, pass it in the header, you're ready. Revoke it whenever you want.
The same coverage as the app
The API queries the same cascade of 30+ providers and the same 4-level verification as the web interface.

}The same data, everywhere you work
Whether you export to HubSpot, pull through the API or work inside the app, the data comes from the same source: the Listar cascade.
30+ providers in cascade
Where competitors query 10 to 20 sources, Listar mobilizes more than 30, including a proprietary dataset and email reconstruction algorithms. The result: 60%+ coverage, sustainably.
4-level verification
Every data point goes through a verification cascade combining third-party providers and a proprietary layer. You export data that lands, not volume.
No middleman
Most cascade-only tools source from the same providers we do. By plugging Listar into your stack, you reach the data at the source.
