# Introduction

> Programmatically schedule AI-driven outbound calls and receive real-time call results.

The Julian API lets you integrate 11x's AI calling platform into your own systems. You can enroll contacts
into an agent's calling sequence, monitor outcomes and credit usage, and receive call results in real time via
webhooks.

## Base URL

All API requests are made to:

```
https://julian.11x.ai/api/v1
```

Full endpoint documentation, with an interactive playground, lives in the **API Reference** tab.

## Typical integration flow

1. Get an API key from the 11x team or from the platform.
2. Validate your key with a read-only request — see [Authentication](/authentication).
3. Enroll contacts via `POST /agents/{agentId}/schedule/sequence` (one contact) or
   `POST /agents/{agentId}/schedule/sequences` (bulk, up to 1,000).
4. Receive call results on your [webhook endpoint](/webhooks) as calls complete.

## Conventions

* Phone numbers should be in **E.164 format** (`+15551234567`).
* Timezones use **IANA names** (`America/New_York`).
* Timestamps are **ISO 8601** strings (`2025-01-20T14:00:00.000Z`).
* Errors return a JSON body with machine-readable `error` and human-readable `message` fields.
