More than an API layer
BlitzAPI aggregates provider APIs behind a single endpoint. Deepline does that too, and adds waterfall enrichment logic, a CLI that AI agents call natively, a PostgreSQL database for persistent storage, and built-in push to CRMs and email sequencers. BYOK mode means you connect your own provider keys and pay $0 in platform fees.
- ✓Use Claude Code, Cursor, or Codex
- ✓Need waterfall enrichment across multiple providers
- ✓Have your own Apollo, Crustdata, or PDL keys
- ✓Want enriched data stored in PostgreSQL automatically
- ✓Need to push results to HubSpot or Instantly
- ✓Want $0 platform fee with your own API keys
- ✓Just need a simple REST endpoint for enrichment
- ✓Want the fastest possible integration into an existing app
- ✓Don't need CLI, database, or CRM integrations
- ✓Prefer a single API key over managing provider keys

Feature comparison
| Feature | Deepline | BlitzAPI |
|---|---|---|
| Interface | CLI + API (agent-native) | REST API only |

| Waterfall enrichment | Built-in with automatic fallback across providers | Manual: caller must implement retry logic |
| Enrichment providers | 30 named providers with transparent pricing | Multiple providers behind a unified API |
| Bring your own API keys | Yes, connect any provider account, use free | No, all calls routed through BlitzAPI billing |
| Pricing model | BYOK free, or managed credits from $0.08/cr | Usage-based per API call |
| Data storage | PostgreSQL database included (your data, your schema) | API responses only, no persistent storage |
| CRM integrations | HubSpot, Salesforce push built-in | No native CRM integrations |
| Email sequencer integrations | Instantly, Lemlist, HeyReach, Smartlead | No native sequencer integrations |
| Claude Code integration | Native skill with slash commands | No Claude Code integration |
| Simple REST API | Yes, API available alongside CLI | Yes, clean, focused REST API |

Key difference
API layer vs full stack
BlitzAPI is an API aggregator. It gives you a single endpoint to query multiple enrichment providers. That is useful if you already have your own orchestration, storage, and CRM push logic. But you have to build and maintain all of that yourself.
Deepline is a full enrichment stack. The CLI handles waterfall logic, the database stores results, and integrations push to your CRM and sequencer. AI agents call deepline enrich the same way they call git or curl.
# Full enrichment workflow in Deepline:
deepline enrich leads.csv --waterfall --providers hunter,prospeo,icypeas
deepline push --provider hubspot --list enriched-q1
deepline sequence --provider instantly --campaign outbound-q1
# BlitzAPI: single API call, you handle the rest
curl -X POST https://api.blitzapi.com/enrich -d '{"email":"..."}'Pricing
Your keys, your rates
BlitzAPI routes all calls through their billing. You pay BlitzAPI per call, potentially at a discount from direct provider rates through volume negotiation, but you cannot bring your own keys.
Deepline's BYOK mode lets you connect your own provider accounts. You pay providers directly at their rates: Hunter, Apollo, Prospeo, Icypeas, and 26 more. Platform fee: $0. If you prefer not to manage keys, Deepline managed credits start at $0.08/cr with transparent per-provider pricing.

Common questions
FAQ
Is Deepline really free?
With BYOK (Bring Your Own Key), Deepline is free: you pay providers directly. Or buy Deepline credits (from $0.08/cr at Scale) and we handle billing. No platform fee, no row limits.
What is BlitzAPI?
BlitzAPI is a data enrichment API aggregator that routes requests to multiple providers behind a single REST endpoint. It focuses on simplifying API integration for developers who want a unified interface for enrichment data.
When should I use BlitzAPI instead of Deepline?
If you just need a simple REST API endpoint to call from your existing application and don't need waterfall logic, CLI tooling, or CRM integrations, BlitzAPI's focused approach may be simpler to integrate. It does one thing (API aggregation) and does it well.
Can AI agents use BlitzAPI?
BlitzAPI is a REST API, so an agent could technically make HTTP calls to it. However, it has no CLI, no native agent skills, and no structured enrichment workflows. Deepline provides a CLI that agents call the same way they call git or curl, plus Claude Code skills for natural language orchestration.
How does pricing compare?
BlitzAPI charges per API call with pricing that may be lower than going to providers directly through bulk negotiation. Deepline's BYOK mode is free: you pay providers at their own rates. With managed credits ($0.08–$0.10/cr), Deepline provides transparent per-provider pricing so you know exactly what each lookup costs.
Does Deepline have a REST API too?
Yes. Deepline has both a CLI and a REST API. The difference is that Deepline also includes waterfall enrichment logic, PostgreSQL storage, CRM push, sequencer integrations, and Claude Code skills. It is a full GTM enrichment stack, not just an API layer.
