# Habeas

**Canonical:** https://apis.io/providers/habeas/  
**APIs profiled:** 0

Habeas was an email reputation and deliverability services provider that helped legitimate senders monitor and manage their sending reputation to maximize inbox deliverability, using a trademark-based accreditation and safelist model to certify permission-based email. Founded in the mid-2000s and backed by Canaan Partners through a Series B round, Habeas was acquired by Return Path in 2008 (habeas.com now redirects to returnpath.com); Return Path was in turn acquired by Validity in 2019. The company is defunct as an independent brand and publishes no live public API or developer surface, so this profile is retained as a Canaan Partners portfolio-history record rather than an active API provider.
