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.

Clean your CRM in one command

Why CRM data rots

B2B contact data decays 25-30% per year. People change jobs. Emails bounce. Companies merge or shut down. Your CRM fills up with stale records that break routing rules and waste SDR time.

The most cost-effective way to keep your CRM clean: run background agents that check job changes daily, validate emails, and flag stale records automatically.

How to clean your CRM

Step 1: Export your contacts

Pull a segment from HubSpot, Salesforce, or Attio as a CSV. Include email, name, company, and any fields you want to validate.

Step 2: Run a pilot cleanup

Tell Claude Code

Take this CSV of 5,000 HubSpot contacts. Re-enrich via waterfall. Validate every email. Flag anyone whose job title changed. Deduplicate by email + LinkedIn URL. Start with 50 as a pilot.

Claude Code reads your Deepline skills and runs:

deepline enrich --input crm-export.csv --with-waterfall email --with 'validate=leadmagic_email_validation' --rows 0:49

Step 3: Review what Deepline flags

For each contact, the output shows:

Email status: valid, catch-all, or bounced
Job change: new title and company if detected
Duplicate cluster: other records that match this person

Step 4: Run the full list

Tell Claude Code

Looks good. Run the full list.

Claude Code continues:

deepline enrich --input crm-export.csv --with-waterfall email --with 'validate=leadmagic_email_validation'

Step 5: Write back to CRM

Tell Claude Code

Write the cleaned data back to HubSpot.

Claude Code runs the upsert:

deepline enrich --input output.csv --with hubspot_batch_upsert_objects --payload '{"object_type":"contacts","id_property":"email"}'

Only changed fields update. Good data stays untouched.

What gets flagged

Issue	How Deepline detects it
Bounced email	LeadMagic or IPQualityScore validation
Job change	Title/company mismatch vs. current LinkedIn profile
Duplicate record	Same email or LinkedIn URL across rows
Stale firmographics	Company size, funding, or industry changed

Cost breakdown

Database size	Credits	Managed mode cost
500 contacts	250	~$25
5,000 contacts	2,500	~$250
50,000 contacts	25,000	~$2,500

Compare to ZoomInfo Enrich at $15K/yr or manual spot-checks at 40+ hours per quarter.

Who uses this

RevOps leads responsible for data quality
Ops teams running quarterly hygiene before board reporting
Sales managers tired of reps calling people who left 6 months ago

Deploy background agents for ongoing cleanup

Instead of quarterly manual cleanups, deploy background agents that run daily:

Tell Claude Code

Deploy this as a background agent that checks job changes daily. Send me a Slack message with a summary of changes and let me approve before writing back to HubSpot.

Claude Code deploys:

deepline workflows deploy crm-cleanup --trigger cron --schedule "0 8 * * *" --notify slack

Background agents research accounts across multiple providers, detect job changes, validate emails, and surface changes for your approval - all without manual exports.

Common questions

Frequently Asked Questions

1Does this overwrite good data?+

No. Deepline only updates fields where it found newer information. If a field is blank in the enrichment, the original value stays.

2What CRMs are supported?+

HubSpot, Salesforce, and Attio have native integrations. For others, export/import via CSV.

3How do I handle duplicates?+

Deepline clusters them for review. You decide which record to keep.
