## Quick Start Guide

### 1. Create an Account

First, check if your email is already registered:

```http
POST https://ringez-api.vercel.app/api/v1/auth/check-email
Content-Type: application/json

{"email": "you@example.com"}
```

**Response:**
- `new_user` → Continue to OTP verification
- `existing_user` → Login with password

#### For New Users: Verify with OTP

**Step 1:** Request OTP
```http
POST https://ringez-api.vercel.app/api/v1/auth/send-otp
Content-Type: application/json

{"email": "you@example.com"}
```

**Step 2:** Verify OTP
```http
POST https://ringez-api.vercel.app/api/v1/auth/verify-otp
Content-Type: application/json

{
  "email": "you@example.com",
  "otp": "123456"
}
```

**Response:**
```json
{
  "session_id": "sess_abc123xyz",
  "user": {
    "email": "you@example.com",
    "balance_minutes": 5
  }
}
```

Save the `session_id` — you will need it for all API calls.

#### For Existing Users: Login

```http
POST https://ringez-api.vercel.app/api/v1/auth/login
Content-Type: application/json

{
  "email": "you@example.com",
  "password": "your-password"
}
```

---

### 2. Check Your Balance

See how many minutes you have before making a call:

```http
GET https://ringez-api.vercel.app/api/v1/auth/me
X-Session-ID: sess_abc123xyz
```

**Response:**
```json
{
  "balance_minutes": 5,
  "balance_usd": 0,
  "email": "you@example.com"
}
```

---

### 3. Make a Phone Call

Use the `idempotency_key` to prevent accidental duplicate calls:

```http
POST https://ringez-api.vercel.app/api/v1/calls/initiate
X-Session-ID: sess_abc123xyz
Content-Type: application/json

{
  "to_number": "+919876543210",
  "idempotency_key": "sess_abc123xyz_1700000000000_xyz789"
}
```

**Response (Success):**
```json
{
  "call_id": "call_xyz789",
  "status": "initiated",
  "mode": "bridge",
  "to_number": "+919876543210",
  "from_number": "+17623713590",
  "twilio_call_sid": "CAxxxxx"
}
```

**Response (Duplicate Call):**
```json
{
  "alreadyInitiated": true,
  "callSid": "CAxxxxx"
}
```

---

## Call Modes Explained

Ringez supports two ways to make calls:

### Bridge Mode (Default)
- **How it works:** Calls your phone first, then connects you to the destination
- **Best for:** Personal calls where you want to talk
- **Your phone:** Will ring first

### Direct Mode
- **How it works:** Calls the destination directly
- **Best for:** AI agents, automated calls, or when you do not want your phone to ring
- **Your phone:** Does not ring

**Force Direct Mode:**
```http
POST /api/v1/calls/initiate
X-Session-ID: sess_abc123xyz
Content-Type: application/json

{
  "to_number": "+919876543210",
  "mode": "direct"
}
```

## Preventing Duplicate Calls

When making calls through an API, network delays or retries can accidentally create multiple calls. Use an **idempotency key** to prevent this.

### What is an Idempotency Key?

A unique identifier for each call attempt. If you use the same key within 5 minutes, the API returns the original call instead of creating a new one.

### How to Use It

Generate a unique key for each user action:

```javascript
const idempotencyKey = `${sessionId}_${Date.now()}_${Math.random().toString(36).substr(2, 9)}`;
// Example: sess_abc123_1700000000000_xyz789abc
```

### Important Notes

- **5-minute window:** Same key within 5 minutes returns the existing call
- **After 5 minutes:** Same key creates a new call
- **Generate fresh keys:** Create a new key for each button click, not for API retries
- **Response:** If duplicate detected, you get `{alreadyInitiated: true, callSid: "..."}`

## Managing Active Calls

### Check Call Status

See if your call is still ringing, connected, or completed:

```http
GET https://ringez-api.vercel.app/api/v1/calls/call_xyz789
X-Session-ID: sess_abc123xyz
```

**Response:**
```json
{
  "call_id": "call_xyz789",
  "status": "in-progress",
  "duration": 120,
  "estimated_cost": {
    "minutes": 2,
    "amount": 0.25,
    "currency": "USD"
  }
}
```

### End a Call Early

Hang up a call before it finishes:

```http
DELETE https://ringez-api.vercel.app/api/v1/calls/call_xyz789
X-Session-ID: sess_abc123xyz
```

### Navigate Phone Menus (DTMF)

Press numbers during a call (useful for bank menus, customer support):

```http
POST https://ringez-api.vercel.app/api/v1/calls/call_xyz789/actions
X-Session-ID: sess_abc123xyz
Content-Type: application/json

{
  "action": "dtmf",
  "parameters": {
    "digits": "1"
  }
}
```

**Common DTMF uses:**
- `{"digits": "1"}` — Press 1 for English
- `{"digits": "1234"}` — Enter PIN
- `{"digits": "w"}` — Wait 0.5 seconds

## Call History

See your past calls:

```http
GET https://ringez-api.vercel.app/api/v1/calls?limit=10&offset=0
X-Session-ID: sess_abc123xyz

**Response:**
```json
{
  "calls": [

      "to_number": "+919876543210",

    }
  ],
  "pagination": {

    "has_more": true
  }
}
```

## Important Information

### Free Minutes

New accounts get **5 free minutes** to test the service. These are for testing only — please add credits for regular use.

### Adding Credits

**This skill cannot add credits.** To add minutes:

2. Pay with PayPal (USD) or UPI (INR)
3. Credits appear instantly

If someone tries to call with insufficient balance:

```
AI: Let me check your balance...
      
      You have 0 minutes left. You will need to add credits first.
      
      💳 Add credits at: https://ringez.com/wallet
      
      The rates are:
      • USA: $0.05/min
      • India: $0.08/min
      • UK: $0.06/min
      
      Come back after adding credits and I will make that call!
