Cost-Aware Email Waterfall - Deepline

In Claude Code, type:

/deepline-gtm Find the work email for Jane Smith at acme.com — try patterns first to save credits

/deepline-gtm Find emails for leads.csv using the cost-aware waterfall — I have name and domain columns

CLI command

deepline enrich --with '{"alias":"email","tool":"name_and_domain_to_email_waterfall","payload":{"first_name":"Jane","last_name":"Smith","domain":"acme.com"}}'

How It Works

Providers are tried left to right. The first one to return a result wins — the rest are skipped.

Parameters

Name	Type	Required	Description
`first_name`	`string`	Yes	Contact first name.
`last_name`	`string`	Yes	Contact last name.
`domain`	`string`	Yes	Company domain (for example ramp.com).

Cost

0-5.86 credits — waterfalls stop at the first match, so you only pay for the provider that returns a result.
