Overview

A1Base is an API platform for giving AI agents a phone number, an email address, and a trusted identity. The site positions it as infrastructure for moving agents beyond chat interfaces and into real-world communication channels.

The product family on the site includes A1Base for phone and identity workflows, and A1Mail for email workflows. Pricing pages show structured plans for messaging volume, analytics, support, and enterprise options, while the main site also links to developer documentation, SDKs, account access, and a dashboard.

Trusted agent identity

Offer a trusted identity layer for agents, positioning the platform around safer and more reliable real-world interactions.
