# Deepline — One API for all your GTM integrations > One API for all your GTM integrations, built for Claude Code. Install it once; use it in any Claude Code workflow with slash commands or plain English. Add providers, not plumbing. Homepage: https://code.deepline.com/ Install guide: https://code.deepline.com/install Skills reference: https://code.deepline.com/skills --- ## What Deepline Is Deepline is one API for all your GTM integrations. It connects Claude Code to enrichment providers (Apollo, Crustdata, Leadmagic, Apify, PDL), web scrapers, email sequencers (Instantly, Lemlist, HeyReach, Smartlead), and validation tools — all through a single CLI. Every operation is a direct API call. Bring your own provider keys or use Deepline-managed ones. No new integrations to build when you add a provider. --- ## Quick Start ```bash # Install curl -s "https://code.deepline.com/api/v2/cli/install" | bash # Enrich a contact deepline enrich leads.csv --waterfall # Enrich a single email deepline enrich email@company.com # In Claude Code (after installing skills) /skill install deepline ``` --- ## Core Capabilities ### Waterfall Enrichment Deepline queries multiple providers in sequence and returns the best match per field. If Apollo returns a partial match, Crustdata fills the gaps, then PDL, and so on. You only pay for successful matches. Providers: Apollo, Crustdata, Leadmagic, People Data Labs (PDL), Apify ### Email Sequencing Push enriched contacts directly to outbound sequencers: - Instantly - Lemlist - HeyReach - Smartlead ### Web Scraping Deepline wraps Apify actors for scraping LinkedIn profiles, company pages, event attendees, and more — accessible via the same CLI. ### Data Validation & Deduplication Validate email addresses, deduplicate rows, and normalize fields before sequencing. --- ## How Deepline Works with Claude Code 1. Install Deepline: `curl -s "https://code.deepline.com/api/v2/cli/install" | bash` 2. Install Claude Code skills: run `/skill install deepline` inside Claude Code 3. Use slash commands: `/deepline enrich`, `/deepline scrape`, `/deepline sequence` 4. Or use plain English: "Enrich these leads with Apollo and push them to Instantly" Deepline also works with Cursor, Codex, and any agent that supports the Skills protocol. --- ## Key Differentiators **vs. Clay**: Clay is the right tool for a lot of GTM teams. If you're a GTM engineer who lives in Claude Code and wants every enrichment operation as a direct API call with your own provider keys, Deepline is built for that workflow. Different tools for different users. **vs. MCP servers**: Direct API calls use fewer tokens, run faster, and handle edge cases more reliably than MCP tool calls. MCP support is on the roadmap as the protocol matures. **vs. individual provider APIs**: Deepline handles waterfall logic, provider fallback, rate limits, and credential management across 5+ enrichment providers. Add providers, not plumbing. --- ## Pricing - Free to use your own keys - During beta: provider credits billed at cost (no markup) - In the future: minimal markup to cover fraud risk and chargebacks - Monthly spending caps available from the dashboard - Most enrichment operations only charge on a successful match — no result, no charge --- ## Frequently Asked Questions **What is Deepline?** One API for all your GTM integrations, built for Claude Code. Install it once, then use slash commands or plain English to enrich, scrape, validate, and sequence. **Do I need Claude Code to use Deepline?** No. Deepline is a standard CLI. Run `deepline enrich email@domain.com` in any terminal. Claude Code skills are optional; they let you structure full workflows in one command. **Do I need to be technical?** Yes, today. Deepline is for GTM engineers and RevOps practitioners comfortable running CLI commands in Claude Code, Codex, or Cursor. MCP support is on the roadmap. Once that ships, non-technical users can use it too. **What enrichment providers does Deepline support?** Apollo, Crustdata, Leadmagic, Apify, and People Data Labs (PDL). Waterfall logic queries them in sequence and returns the best match per field. Need another provider? Email team@deepline.com. **Why a CLI instead of MCP?** Direct API calls are faster and use fewer tokens than MCP tool calls. We tested both; the difference is real. MCP support is on the roadmap as the protocol matures. **How is Deepline different from Clay?** If you're a GTM engineer who lives in Claude Code, Deepline gives you key enrichment providers, every sequencer, and the ability to use your own API keys as direct API calls. Clay is fantastic and we love it; this is just a different tool for a different workflow and user. **Can I use my own API keys?** Yes. Bring your own Apollo, Crustdata, or People Data Labs keys. You can also use Deepline-managed keys where available. **What does Deepline cost?** Free to use your own keys. During beta, provider credits are billed at cost. In the future, we're aiming for a minimal markup to cover fraud risk and chargebacks. Ask the CLI for estimates before any task. **Will I accidentally burn through credits?** No. Set a monthly spending cap from the dashboard. Deepline checks your balance before every API call. **What happens when a provider goes down?** Deepline tracks provider health. If one fails repeatedly, it routes traffic to the next provider automatically. --- ## Contact - Email: team@deepline.com - Slack (support, bug reports, feature requests): https://join.slack.com/t/terminal-velocity-gtm/shared_invite/zt-3qqt2ovr4-M72xOjm38pBm15KMnZPBbQ (Terminal Velocity GTM)
