Questions
Can a B2B data API replace ZoomInfo enrichment for a sales team?
Partly. An enrichment API fills CRM fields or adds context by domain or email, and the calls run from your own systems. The Autobound Signal API adds dated events (news, hiring, SEC filings, job changes) to a company domain or a contact, and charges 2 credits per result. It is not a contact database, so a team that dials from the tool still needs a contact data vendor.
