# Quickenrich API Guide for GTM Workflows

> Use free lookup endpoints to discover valid filters, search masked contacts for free, then reveal only selected contacts.

## Playbook

Use QuickEnrich lookup endpoints before contact or company finder searches when a filter requires an exact provider value.

Use `quickenrich_contact_search` to find masked candidates for free. Reveal only selected rows with `quickenrich_contact_reveal`.

Check each tool's Deepline pricing before running billable email, phone, reverse-email, dataset, reveal, or company searches. A customer-owned API key takes precedence over Deepline's managed key and is not billed by Deepline.
