Key difference
BlitzAPI is an API layer. Deepline is a workflow stack.
BlitzAPI is focused and useful if your main need is a unified enrichment API. Deepline covers that same API layer, then adds waterfall orchestration, persistent storage, sequencer and CRM destinations, and first-party agent tooling.
That makes Deepline heavier if you only want a raw endpoint, but much stronger if your team is trying to automate end-to-end GTM workflows rather than just normalize provider calls.
Who should use what
Choose the right fit
Choose Deepline if you...
- Need CLI-first automation for agents
- Want waterfall enrichment and built-in storage
- Care about BYOK and provider-level pricing transparency
Choose BlitzAPI if you...
- Only want a simple REST API
- Already have your own orchestration layer
- Do not need CRM or sequencer integrations in the platform

Common questions
FAQ
What is BlitzAPI?+
BlitzAPI is a data enrichment API aggregator that exposes multiple providers behind one REST surface for developers.
When should I use BlitzAPI instead of Deepline?+
If you want only a simple REST layer inside an existing application and do not need waterfall logic, storage, or agent tooling, BlitzAPI can be the simpler integration.
Can AI agents use BlitzAPI?+
They can make HTTP calls to it, but there is no CLI, no agent skill layer, and no built-in enrichment workflows. Deepline is purpose-built for that path.
Does Deepline have a REST API too?+
Yes. Deepline includes an API and a CLI. The key difference is the higher-level workflow layer around them.
