}'How it works
From zero to signals in three steps
No SDKs to install. No schemas to learn. Just HTTPS and JSON.
01
Get your API key
Create your free account and grab an API key. You'll be making calls in under 60 seconds.
02
Make your first call
Search, enrich, or filter by signal type. Every endpoint returns clean JSON with consistent schemas.
03
Go live
Pipe signals into your CRM, data warehouse, or AI workflows. We handle the infrastructure.
Endpoints
