# Quo

Access the Quo API with managed OAuth authentication. Send SMS messages, manage calls and contacts, and retrieve call recordings and transcripts.

## Quick Start

```bash
# List phone numbers
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/quo/v1/phone-numbers')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('User-Agent', 'Maton/1.0')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

## Base URL

```
https://gateway.maton.ai/quo/{native-api-path}
```

Replace `{native-api-path}` with the actual Quo API endpoint path. The gateway proxies requests to `api.openphone.com` and automatically injects your OAuth token.

## Authentication

All requests require the Maton API key in the Authorization header and a User-Agent header:

```
Authorization: Bearer $MATON_API_KEY
User-Agent: Maton/1.0
```

**Environment Variable:** Set your API key as `MATON_API_KEY`:

```bash
export MATON_API_KEY="YOUR_API_KEY"
```

### Getting Your API Key

1. Sign in or create an account at [maton.ai](https://maton.ai)
2. Go to [maton.ai/settings](https://maton.ai/settings)
3. Copy your API key

## Connection Management

Manage your Quo OAuth connections at `https://ctrl.maton.ai`.

### List Connections

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=quo&status=ACTIVE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Create Connection

```bash
python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'quo'}).encode()
req = urllib.request.Request('https://ctrl.maton.ai/connections', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Get Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

**Response:**
```json
{
  "connection": {
    "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "quo",
    "metadata": {}
  }
}
```

Open the returned `url` in a browser to complete OAuth authorization.

### Delete Connection

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections/{connection_id}', method='DELETE')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Specifying Connection

If you have multiple Quo connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/quo/v1/phone-numbers')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('User-Agent', 'Maton/1.0')
req.add_header('Maton-Connection', '21fd90f9-5935-43cd-b6c8-bde9d915ca80')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If omitted, the gateway uses the default (oldest) active connection.

```

## Pagination

Quo uses token-based pagination. Include `maxResults` to set page size and use `pageToken` to retrieve subsequent pages.

```bash
GET /quo/v1/contacts?maxResults=50&pageToken=eyJsYXN0SWQiOi...
```

Response includes pagination info:

```json
{
  "data": [...],
  "totalItems": 150,
  "nextPageToken": "eyJsYXN0SWQiOi..."
}
```

When `nextPageToken` is `null`, you've reached the last page.

## Code Examples

### JavaScript

```javascript
const response = await fetch(
  'https://gateway.maton.ai/quo/v1/phone-numbers',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'User-Agent': 'Maton/1.0'
    }
  }
);
const data = await response.json();
```

### Python

```python
import os
import requests

response = requests.get(
    'https://gateway.maton.ai/quo/v1/phone-numbers',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'User-Agent': 'Maton/1.0'
    }
)
data = response.json()
```

### Send SMS Example

```python
import os
import requests

response = requests.post(
    'https://gateway.maton.ai/quo/v1/messages',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'User-Agent': 'Maton/1.0',
        'Content-Type': 'application/json'
    },
    json={
        'content': 'Hello from Quo!',
        'from': 'PN123abc',
        'to': ['+15555555555']
    }
)
data = response.json()
```

## Notes

- Phone number IDs start with `PN`
- User IDs start with `US`
- Call/Message IDs start with `AC`
- Phone numbers must be in E.164 format (e.g., `+15555555555`)
- SMS pricing: $0.01 per segment (US/Canada); international rates apply
- Maximum 1600 characters per message
- List calls requires exactly 1 participant (1:1 conversations only)
- IMPORTANT: All API requests require a `User-Agent` header (e.g., `User-Agent: Maton/1.0`). Requests without this header will be blocked.
- IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets (`participants[]`) to disable glob parsing
- IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Bad request (e.g., too many participants, invalid format) |
| 401 | Invalid or missing Maton API key |
| 402 | Insufficient credits for SMS |
| 403 | Not authorized for this phone number |
| 404 | Resource not found |
| 429 | Rate limited |
| 500 | Server error |

### Troubleshooting: API Key Issues

1. Check that the `MATON_API_KEY` environment variable is set:

```bash
echo $MATON_API_KEY
```

2. Verify the API key is valid by listing connections:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

### Troubleshooting: Invalid App Name

1. Ensure your URL path starts with `quo`. For example:

- Correct: `https://gateway.maton.ai/quo/v1/phone-numbers`
- Incorrect: `https://gateway.maton.ai/openphone/v1/phone-numbers`
