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 45+ 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 45+ 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.

Score inbound leads before they hit CRM

Why most inbound leads are junk

Leads come in from forms, ads, and events. Marketing passes everything to sales. SDRs spend hours qualifying leads that were never going to close.

The fix: enrich and score every lead before it hits the CRM. SDRs only see the ones worth calling.

How to set up inbound scoring

Step 1: Define your ICP criteria

Write out what makes a good lead:

Series B+ SaaS company
100-500 employees
US-based
Uses Snowflake or dbt (bonus)

Step 2: Create the webhook workflow

Tell Claude Code

When a new lead hits HubSpot via form submission, enrich them with firmographics and score against our ICP: Series B+ SaaS, 100-500 employees, US-based. Write the score back to the HubSpot contact.

Claude Code reads your Deepline skills and generates a workflow. Behind the scenes, it runs:

deepline workflows apply --spec inbound-scoring.yaml

Step 3: Test with a sample lead

Tell Claude Code

Test the workflow with a sample lead.

Deepline runs the workflow on one lead first. You see:

Firmographic data pulled (company size, industry, funding)
ICP score (1-10)
Which fields wrote back to HubSpot

Step 4: Deploy the webhook

Tell Claude Code

Deploy the workflow and give me the webhook URL.

Claude Code deploys and returns:

deepline workflows deploy inbound-scoring --trigger webhook
# → https://api.deepline.com/v2/workflows/inbound-scoring/trigger

Point your HubSpot form submission trigger at the webhook URL. Every new lead gets enriched and scored in under 5 seconds.

What gets enriched

Data point	Providers
Company size	Apollo, People Data Labs, Crustdata
Industry	Apollo, People Data Labs
Funding stage	Crunchbase via Crustdata
Tech stack	BuiltWith, TheirStack
Location	Apollo, People Data Labs

How scoring works

Claude evaluates each lead against your ICP:

Score 1-10 where:
- 9-10: Perfect ICP fit
- 7-8: Good fit, worth pursuing
- 4-6: Marginal, may require qualification
- 1-3: Not ICP, do not route to sales

The score and reasoning write back to a custom field in your CRM.

Cost breakdown

Inbound volume	Credits/month	Managed mode cost
100 leads	50	~$5
1,000 leads	500	~$50
10,000 leads	5,000	~$500

Compare to 6sense at $50K+/yr or manual SDR qualification.

Who uses this

Marketing ops enriching leads before handoff
Demand gen measuring campaign quality by score, not just volume
PLG teams automating sign-up qualification

Common questions

Frequently Asked Questions

1How fast is the enrichment?+

Under 5 seconds from form submit to CRM writeback.

2Can I customize the scoring rubric?+

Yes. Add or remove criteria, change weights, adjust thresholds.

3What if firmographic data is missing?+

Deepline tries multiple providers (Apollo, People Data Labs, Crustdata). If all miss, the score reflects 'insufficient data' and the lead gets flagged for manual review.

Inbound scoring flow: form submit, webhook, enrich, score, write to CRM
