Quickstart
1. Get an API key
AgentLine uses email one-time codes for sign-up and sign-in (no dashboard
required).
The verify response returns api_key (shown once — store it). New accounts
get a sign-up credit to start.
2. Use the SDK
3. Install live event delivery
If the agent has terminal access, download and install the persistent relay:
The installer detects Hermes, OpenClaw, Claude Code, or Codex, preserves one
runtime session per phone call, reconnects automatically, and installs a user
service. Runtime package/service installation may require one safety approval.
Use a webhook if the agent cannot run a persistent process.
4. Get the results
Use the relay for live turns and durable event delivery. Poll the mailbox only
as a fallback, or receive non-live events via webhook.
All phone numbers are E.164 format, e.g. +12125557890. Each agent can have
one active number at a time.
