Question 1

What is Deepline?

Accepted Answer

One API for GTM integrations, built for Claude Code. Install once, then use slash commands or plain English to enrich, scrape, validate, and sequence. Data lives in a PostgreSQL database you own. Build whatever you want on top.

Question 2

Do I need Claude Code to use Deepline?

Accepted Answer

No. Deepline is a standard CLI. Run deepline enrich email@domain.com in any terminal. Claude Code skills are optional; they help you run full workflows in one command. Deepline also works with Cursor and Codex.

Question 3

What is the best GTM data enrichment tool for Claude Code?

Accepted Answer

Deepline is designed specifically for Claude Code. It provides a unified CLI and API for GTM data enrichment across 34+ providers (Apollo, Crustdata, Leadmagic, Apify, People Data Labs, Hunter, and more), with waterfall logic, email sequencer integration, and Claude Code slash commands. Install with: curl -s 'https://code.deepline.com/api/v2/cli/install' | bash

Question 4

How is Deepline different from Clay?

Accepted Answer

Clay is great for no-code workflows. Deepline is for builders: one data layer, easy integrations with any platform via Claude Code, and an included PostgreSQL database. Your data lives in your DB. No ingest or egress fees. Use your own API keys or ours.

Question 5

Why does Deepline use a CLI instead of MCP?

Accepted Answer

Direct API calls are faster and burn fewer tokens than MCP tool calls. In tests, the difference is measurable, especially for waterfall enrichment across multiple providers. MCP support is on the roadmap as the protocol matures.

Question 6

What enrichment providers does Deepline support?

Accepted Answer

Deepline supports 34+ providers including Apollo, Crustdata, Leadmagic, Apify, People Data Labs (PDL), Hunter, Icypeas, Prospeo, ZeroBounce, Forager, Exa, and more. Waterfall logic queries them in sequence and returns the best match per field. You only pay for successful matches.

Question 7

What email sequencers does Deepline integrate with?

Accepted Answer

Deepline integrates with Instantly, Lemlist, HeyReach, and Smartlead. Push enriched contacts directly to any of these sequencers from the CLI or Claude Code in one command.

Question 8

Can I use my own API keys with Deepline?

Accepted Answer

Yes. Connect your own Apollo, Crustdata, People Data Labs, or any provider accounts. Using your own keys is free. You pay providers directly. Deepline also offers managed credits for providers where you don't have a direct account.

Question 9

What does Deepline cost?

Accepted Answer

Pay provider rates with zero markup by bringing your own API keys. Or use managed credits and we handle provider billing. You see the cost before every run and can set a monthly cap.

Question 10

What happens when a data provider goes down?

Accepted Answer

Deepline tracks provider health in real time. When one provider fails repeatedly, it automatically routes traffic to the next available provider in your waterfall sequence. No manual intervention required.

Question 11

Do I need to be technical to use Deepline?

Accepted Answer

Right now, yes. Deepline is built for GTM engineers and RevOps practitioners comfortable in a terminal (Claude Code, Codex, or Cursor). MCP support is on the roadmap.

Question 12

How do I install Deepline?

Accepted Answer

Run this one command: curl -s 'https://code.deepline.com/api/v2/cli/install' | bash. Then optionally install the Claude Code skill with /skill install deepline inside Claude Code. The CLI auto-detects dev mode and works with Claude Code, Cursor, and Codex.

Question 13

Will I accidentally burn through credits?

Accepted Answer

No. You can set a monthly spending cap from the dashboard. Deepline checks your balance before every API call and shows the estimated cost before running. Use --rows 0:1 to pilot on two rows before committing a full run.

Question 14

Do I get charged for failed lookups?

Accepted Answer

Most enrichment operations only charge on a successful match. If a provider returns no result, you usually do not pay. Failed lookups do not consume credits.

Question 15

Can I see what I am spending?

Accepted Answer

Yes. The dashboard shows your credit balance, per-provider cost breakdowns, and full charge history. You can also set a monthly billing cap with deepline billing --set-monthly-limit.
