Deepline Quickstart

Deepline is an SDK + CLI designed for Go-to-Market agents and production applications. In this quickstart you will install the Deepline CLI, authenticate your machine, and run a first enrichment request. The fastest path is Claude Code plus /deepline-gtm; the direct CLI path is deepline quickstart.

Step	What you do
Install	Run the hosted installer and connect this machine.
Ask	Use `/deepline-gtm` in Claude Code or run `deepline quickstart`.
Review	Check the provider route and returned fields.
Scale	Reuse the same workflow for a CSV, API call, or play.

Watch the setup

1. Install

Claude Code
Claude Cowork

Prerequisites

Node.js 20+
Python 3.10+
npm
Claude Code or any AI coding agent

Install CLI

Install the deepline CLI:

curl -fsSL "https://code.deepline.com/api/v2/cli/install" | bash

The installer opens your browser to connect this machine. If deepline is not found after install, restart your terminal and rerun the installer.

Install Deepline as a Claude Cowork plugin instead of running the shell installer.

Open Claude Desktop and switch to Cowork.
Open Customize in the left sidebar.
Click the + next to Personal plugins.
Open Create plugin, then choose Add marketplace.

Add the Deepline plugin marketplace:

https://github.com/getaero-io/deepline-plugins

Install the deepline plugin.
Enable internet access for all domains in the Cowork session settings: open Settings -> Capabilities, turn on Allow network egress, then set Domain allowlist to All domains.
Start a Cowork session and select a project folder.

Selecting a folder lets Deepline persist auth in that workspace, so future Cowork sessions opened on the same folder can reuse the login.

Run:
/deepline-quickstart

The first Deepline command may install the CLI inside the Cowork sandbox. That is expected.Team and Enterprise plans: your organization owner may need to enable Cowork for the workspace. They may also need to allow internet access for all domains, or add the domains you use, in Cowork’s network settings. See Use Claude Cowork on Team and Enterprise plans.

2. Use the skill

The Deepline skill auto-syncs when you install the CLI. In Claude Code, type:

/deepline-gtm Find a verified work email for Jane Smith at Stripe

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. Run your first recipe

Run the guided wizard to pick and run your first recipe:

deepline quickstart

Or type directly in Claude Code:

/deepline-gtm Find the work email for a Chief Marketing Officer in NYC

That’s it. Deepline runs a waterfall across multiple providers and returns a verified work email.

CLI command (advanced)

deepline tools execute company_to_contact_by_role_waterfall \
  --payload '{"company_name":"Acme","domain":"acme.com","roles":["Chief Marketing Officer"]}'

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

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

Scale it up

Got a list? Just ask:

/deepline-gtm I have a CSV with company names and domains. Find work emails for the VP of Sales at each one.

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.
