One API for GTM integrations, built for Claude Code. Install once, then use slash commands or plain English to enrich, scrape, validate, and sequence. Data lives in a PostgreSQL database you own. Build whatever you want on top.

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 help you run full workflows in one command. Deepline also works with Cursor and Codex.

What is the best GTM data enrichment tool for Claude Code?

Deepline is designed specifically for Claude Code. It provides a unified CLI and API for GTM data enrichment across 44+ providers (Apollo, Crustdata, Leadmagic, Apify, People Data Labs, Hunter, and more), with waterfall logic, email sequencer integration, and Claude Code slash commands. Install with: curl -s 'https://code.deepline.com/api/v2/cli/install' | bash

How is Deepline different from Clay?

Clay is great for no-code workflows. Deepline is for builders: one data layer, easy integrations with any platform via Claude Code, and an included PostgreSQL database. Your data lives in your DB. No ingest or egress fees. Use your own API keys or ours.

Why does Deepline use a CLI instead of MCP?

Direct API calls are faster and burn fewer tokens than MCP tool calls. In tests, the difference is measurable, especially for waterfall enrichment across multiple providers. MCP support is on the roadmap as the protocol matures.

What enrichment providers does Deepline support?

Deepline supports 44+ providers including Apollo, Crustdata, Leadmagic, Apify, People Data Labs (PDL), Hunter, Icypeas, Prospeo, ZeroBounce, Forager, Exa, and more. Waterfall logic queries them in sequence and returns the best match per field. You only pay for successful matches.

What email sequencers does Deepline integrate with?

Deepline integrates with Instantly, Lemlist, HeyReach, and Smartlead. Push enriched contacts directly to any of these sequencers from the CLI or Claude Code in one command.

Can I use my own API keys with Deepline?

Yes. Connect your own Apollo, Crustdata, People Data Labs, or any provider accounts. Using your own keys is free. You pay providers directly. Deepline also offers managed credits for providers where you don't have a direct account.

What does Deepline cost?

Pay provider rates with zero markup by bringing your own API keys. Or use managed credits and we handle provider billing. You see the cost before every run and can set a monthly cap.

What happens when a data provider goes down?

Deepline tracks provider health in real time. When one provider fails repeatedly, it automatically routes traffic to the next available provider in your waterfall sequence. No manual intervention required.

Do I need to be technical to use Deepline?

Right now, yes. Deepline is built for GTM engineers and RevOps practitioners comfortable in a terminal (Claude Code, Codex, or Cursor). MCP support is on the roadmap.

How do I install Deepline?

Run this one command: curl -s 'https://code.deepline.com/api/v2/cli/install' | bash. Then optionally install the Claude Code skill with /skill install deepline inside Claude Code. The CLI auto-detects dev mode and works with Claude Code, Cursor, and Codex.

Will I accidentally burn through credits?

No. You can set a monthly spending cap from the dashboard. Deepline checks your balance before every API call and shows the estimated cost before running. Use --rows 0:1 to pilot on two rows before committing a full run.

Do I get charged for failed lookups?

Most enrichment operations only charge on a successful match. If a provider returns no result, you usually do not pay. Failed lookups do not consume credits.

Can I see what I am spending?

Yes. The dashboard shows your credit balance, per-provider cost breakdowns, and full charge history. You can also set a monthly billing cap with deepline billing --set-monthly-limit.

Deepline for Marketing Ops

The inbound data gap

Inbound leads arrive with missing firmographics and no ICP score. Marketing passes everything to sales and hopes for the best.

What Deepline does for marketing ops

Real-time enrichment on form submit

Set up a webhook from HubSpot. When a lead submits a form, Deepline enriches and writes back to the CRM typically under 5 seconds.

Tell Claude Code

When a new lead submits our demo form in HubSpot, enrich with firmographics and score 1-10 against our ICP: B2B SaaS, 100-500 employees, Series A+. Write the score back to the contact.

Claude Code applies a webhook workflow:

deepline workflows apply --payload '{"name":"inbound-scoring","trigger":{"type":"webhook"},"steps":[/* enrich + score + writeback */]}'
# After apply, copy the webhook URL from the dashboard at /workflows/inbound-scoring

Firmographic fill

Data point	Providers
Company size	Apollo, People Data Labs, Crustdata
Industry	Apollo, People Data Labs

ICP scoring

Each lead gets scored against your criteria before a human sees it. Sales only works leads that pass the threshold.

Account-level intelligence

Combine firmographics with technographic signals and hiring data for richer qualification.

Use cases by role
