Meaning
What this means for you
If you're searching for "cheapest enrichment tool"
$0 platform fee. You pay providers directly at their published rates. No markup on any call. Deepline adds orchestration, waterfall logic, normalized output schemas, and database storage on top, all at no additional cost. If you already have Apollo, Hunter, or Crustdata accounts, you keep your negotiated rates and existing billing relationship.
If you're searching for "data enrichment without vendor lock-in"
Your keys, your accounts. Deepline never stores your API keys on its servers. Keys live in your local .env file and are passed directly to provider APIs at call time. If you stop using Deepline, your provider accounts and data are untouched. One waterfall can mix BYOK keys for some providers and managed credits for others. No single vendor dependency.
If you're searching for "free enrichment tool"
In BYOK mode, Deepline is genuinely free. The platform charges nothing. You pay providers at their rates. Compare this to platforms that charge $185+/month in platform fees before you make a single enrichment call.
Honest: not ideal if
You have zero provider accounts and want to start enriching immediately. In that case, use managed credits instead. They cost $0.10/credit, with a 10% volume discount on purchases of 1,000+ credits, require no provider signups, and work across all 28 providers.
Model
BYOK means Deepline orchestrates, not tolls
If you already pay Apollo, Hunter, Crustdata, or PDL directly, Deepline should not add a second tax layer on top. BYOK mode keeps the orchestration and workflow benefits while leaving provider billing where it already belongs.
The product still gives you normalized outputs, waterfalls, validation, CLI execution, and database storage. The difference is that the usage bill stays anchored to the vendor you chose.

FAQ
Common questions
What happens if my BYOK key hits a rate limit?+
Deepline respects provider rate limits. If one provider key is rate-limited, the waterfall moves to the next provider in the chain. Deepline does not retry rate-limited requests automatically. It moves forward to avoid wasting your quota and returns a partial result with clear status when needed.
Can I use BYOK and managed credits for the same provider?+
No. For a given provider, your workspace uses either your BYOK key or managed credits, not both at the same time. Connect a BYOK key and all calls to that provider use your key. Remove the key to fall back to managed credits. That keeps billing unambiguous.
Do I need BYOK keys for waterfall enrichment to work?+
No. Waterfall enrichment works with managed credits, BYOK keys, or any combination. Zero keys connected means managed credits handle everything. Three BYOK providers plus two managed-credit providers means the waterfall uses all five in configured priority order.
How do I know which mode was used for each enrichment step?+
Every enrichment response includes the provider chain and the auth mode used at each step. BYOK providers show auth_mode: "byok". Managed credits show auth_mode: "managed". You can audit exactly where each API call went.
How are my API keys stored?+
Every key is encrypted at rest, scoped to your workspace, never shared across tenants, and never logged. Keys are removable on demand via CLI or API. When Deepline makes a call using your key, the request goes directly to the provider API.
