Getting Started
Step 1: Create an API key
- Sign up at corridorkey.app
- Go to your dashboard
- Navigate to API Keys section
- Click "Create API Key" and give it a name
- Copy your key (format: `ck_live_...`) — it's only shown once!
You can create up to 5 API keys per account.
Step 2: Authentication
All API requests use Bearer token authentication:
```
Authorization: Bearer ck_live_your_api_key_here
```
Step 3: Upload and process
The API follows the same flow as the web app:
- Upload video file
- (Optional) Request free single-frame preview
- Start processing job
- Poll for status or receive webhook callback
- Download results (composite + alpha matte)
API Pricing
Same as the web app — no API premium:
| Video Length | Cost |

| 5 minutes | $0.50 |
| 30 minutes | $3.00 |
| 1 hour | $6.00 |
Credits work the same way: buy $5 packs (50 minutes each). Credits purchased through the web app work with the API and vice versa.
