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

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:

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

deepline doctor --json

Operate runs safely

deepline runs get play/my-play/run/20260706t233844-689-b0379871
deepline runs stop-all --dry-run
deepline runs stop-all --reason "incident cleanup"
deepline runs rerun play/my-play/run/20260706t233844-689-b0379871 --idempotency-key incident-42

runs get shows status, current activity, and next steps. stop-all --dry-run lists what would be stopped (workspace-scoped, child runs included) and never cancels anything. A real stop-all reports a run as stopped only when the scheduler confirmed it and exits nonzero on partial or failed stops. runs rerun always sends an Idempotency-Key; reuse an explicit key to repeat an ambiguous result without starting a second rerun (deduplicated: true in --json). From code:

import { DeeplineClient } from 'deepline';

const client = new DeeplineClient();
const runId = 'play/my-play/run/20260706t233844-689-b0379871';
const preview = await client.runs.stopAll({ dryRun: true });
const rerun = await client.runs.rerun(runId, {
  idempotencyKey: 'incident-42',
});
console.log(preview.candidateCount, rerun.deduplicated);

Webhook delivery retries use the existing POST /api/v2/plays/webhook-deliveries/:receiptId path; there is no separate trigger retry, deliveries, health, or debug command.
