Deepline is an SDK + CLI designed for Go-to-Market agents and production applications. In this quickstart you will ask your agent to install Deepline, authenticate your machine, and run a first GTM request through /deepline-gtm.

​
Watch the setup

​
1. Install

​
Prerequisites

  • Claude Code or any AI coding agent
  • Permission for the agent to run setup commands

​
Ask your agent to install Deepline

Paste this into Claude Code, Codex, Cursor, Gemini CLI, or another shell-capable coding agent:
The agent handles Node.js and npm compatibility when the environment allows it, installs the CLI and Deepline skills, starts browser authorization, and verifies the result. If the runtime cannot be changed safely, the agent gives you the exact official install handoff and resumes afterward. In a restricted sandbox it automatically uses a persistent project-local install.You only need to approve the agent’s native command prompt and the Deepline browser authorization.
If this command reports that Node.js or npm is missing or unsupported, install the current Node.js LTS release from nodejs.org and retry, or use the coding agent flow above to handle runtime setup.If setup fails, use the exact retry or diagnostic command in its JSON response. Run deepline doctor --json when setup directs you to diagnose the environment.

​
2. Use the skill

The Deepline skill auto-syncs when you install the CLI. In Claude Code, type:
The /deepline-gtm prefix tells Claude Code to use the Deepline skill, which knows all 97+ integrations, waterfall logic, and cost optimization. Describe what you want in plain English after the prefix.

​
3. Try a starter prompt

Choose one of the same starter workflows offered after setup:
Or describe your own business problem. Your agent will turn it into one concrete /deepline-gtm prompt, show you the reusable prompt, and run it without making you paste it again.
The waterfall tries multiple providers and stops at the first valid hit. You only pay for the one that finds the email. Single-provider enrichment commonly leaves coverage gaps. Waterfall enrichment improves match rates by querying multiple providers in sequence. Specific lift varies by ICP and region.

​
What just happened

  1. Deepline searched for a CMO in NYC across prospecting providers
  2. It ran a waterfall across email providers
  3. The first provider to return a valid, verified email wins
  4. You paid for one successful lookup

​
Scale it up

Got a list? Just ask:
Deepline reads your file, picks the right waterfall, and enriches every row. Pilot mode: Add “just test on the first 2 rows” to any prompt to review before processing the full file.
