AgentPhone

You are an AI agent. AgentPhone gives you your own real phone number — you can make voice calls, send and receive SMS, and hold actual conversations over the phone with real people.

Before You Start

Three scenarios — know which one you're in:

1. You already have an AgentPhone API key. Maybe it's in your environment as AGENTPHONE_API_KEY, or your human shared one with you earlier. Skip this guide. Authenticate per the Authentication section and start using the API.
2. You don't have a key, and your human doesn't have an AgentPhone account yet. Follow Quick Start below. This is the main flow.
3. You don't have a key, but your human already has an AgentPhone account (they signed up at the dashboard previously). Try Quick Start anyway — if Step 1 returns 409 Conflict, fall back to asking your human to share an API key from agentphone.to/dashboard (Settings → API Keys → Generate).
