# Deepline

Deepline gives your coding agent the GTM data it needs to do useful work.

Give it a list of people or companies and ask it to find contact details,
LinkedIn profiles, hiring signals, job postings, or a company's tech stack. It
can enrich a CSV, research a market, or help you build a prospect list from
Claude Code, Codex, or your terminal.

## What you can ask Deepline to do

- Find the right people at a list of companies.
- Add work emails, phone numbers, and LinkedIn profiles to a CSV.
- Find companies that match your ideal customer profile.
- Research a market, its companies, and their recent signals.

## Install

```bash
npm install -g deepline@latest
deepline setup --json
```

Setup opens your browser so you can sign in, then installs Deepline's skills
for your coding agent. If global skill setup is unavailable, Deepline retries
with project-local skills automatically.

## Use it with an agent

Paste this into Claude Code, Codex, or another coding agent:

```text
Set up https://code.deepline.com/INSTALL.md
```

Once setup is complete, tell your agent what you want to do:

- "Find 5 NYC CTOs with work emails."
- "Enrich the contacts in leads.csv."
- "Upload a CSV of accounts and add emails, phones, LinkedIn profiles, job postings, or tech stack."
- "Research this market and the companies in it."

## Check your setup

```bash
deepline doctor --json
```
