Documentation
Give your agent aphone number.
Saperly is the phone carrier for AI agents. One API call gives any agent a real number — voice, SMS, identity, and compliance built in. The audio never touches your servers.
Quickstart
One API call to a live number. Node, Python, or curl — under five minutes.
How Saperly works
The whole mental model: numbers, connections, balance, and compliance.
Voice channels
Call your own coding agent and talk to it in its context, tools intact.
API reference
Every endpoint, typed, with a try-it playground in the browser.
Audio never touches your servers
Saperly runs the phone network so you don't have to. Speech-to-text and text-to-speech happen in-network. Even when your own model drives the call, you only ever handle text — transcribed turns in, your replies out. There is no audio pipeline for you to operate and nothing of yours that has to stay online for a call to connect.
