oxygen › Oxygen waterfalls email (Prospeo → LeadMagic → Hunter) and phone providers per row, marks each email's deliverability, and records the source on every cell.
Finding a reachable email or a mobile number usually means paying several providers and stitching the results together. Oxygen does the stitching: one request, a waterfall across providers, deliverable contact data back.
From Claude Code, hand Oxygen a list of people and it finds a verified work email and a direct dial for each, falling back across providers until it has a hit, and recording where each value came from.

Frequently asked questions
Are the emails verified?
Oxygen marks each email's deliverability so you can suppress risky addresses before you send. The waterfall keeps trying providers until it finds a deliverable address.
Can I get phone numbers too?
Yes. Oxygen waterfalls phone providers for mobiles and direct dials in the same run as email.
What do I need to start?
A name plus a company domain or a LinkedIn URL per person is enough for the waterfall to resolve contact data.
