## Authentication
|
||||||
|
|
||||||
|
The IOPaint API uses API keys for authentication. All requests must include your API key in the request header.
|
||||||
|
|
||||||
|
### Obtaining an API Key
|
||||||
|
|
||||||
|
1. Sign up at [https://iopaint.com/signup](https://iopaint.com/signup)
|
||||||
|
2. Navigate to your [Dashboard](https://iopaint.com/dashboard)
|
||||||
|
3. Generate a new API key
|
||||||
|
4. Store it securely (keys cannot be recovered)
|
||||||
|
|
||||||
|
### Using Your API Key
|
||||||
|
|
||||||
|
Include your API key in the `X-API-Key` header with every request:
|
||||||
|
|
||||||
|
```http
|
||||||
|
X-API-Key: your_api_key_here
|
||||||
|
```
|
||||||
|
|
||||||
|
### Security Best Practices
|
||||||
|
|
||||||
|
- ⚠️ **Never expose your API key in client-side code**
|
||||||
|
- ✅ Store keys in environment variables
|
||||||
|
- ✅ Rotate keys periodically
|
||||||
|
- ✅ Use different keys for development and production
|
||||||
|
- ✅ Revoke compromised keys immediately
|
||||||
|
|
||||||
|
### Example
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# ✅ Correct
|
||||||
|
curl https://api.iopaint.com/api/v1/health \
|
||||||
|
-H "X-API-Key: $IOPAINT_API_KEY"
|
||||||
|
|
||||||
|
# ❌ Incorrect (hardcoded key)
|
||||||
|
curl https://api.iopaint.com/api/v1/health \
|
||||||
|
-H "X-API-Key: sk_live_1234567890abcdef"
|
||||||
|
```

## Rate Limiting
|
||||||
|
|
||||||
|
### Rate Limit Rules
|
||||||
|
|
||||||
|
| Plan | Rate Limit | Burst | Quota |
|
||||||
|
|------|------------|-------|-------|
|
||||||
|
| **Free** | 2 req/min | 5 | 10/day |
|
||||||
|
| **Basic** | 10 req/min | 20 | 3,000/month |
|
||||||
|
| **Pro** | 30 req/min | 60 | 20,000/month |
|
||||||
|
| **Enterprise** | Custom | Custom | Custom |
|
||||||
|
|
||||||
|
### Rate Limit Headers
|
||||||
|
|
||||||
|
Every response includes rate limit information:
|
||||||
|
|
||||||
|
```http
|
||||||
|
X-RateLimit-Limit: 10
|
||||||
|
X-RateLimit-Remaining: 7
|
||||||
|
X-RateLimit-Reset: 1672531200
|
||||||
|
```
|
||||||
|
|
||||||
|
| Header | Description |
|
||||||
|
|--------|-------------|
|
||||||
|
| `X-RateLimit-Limit` | Maximum requests per time window |
|
||||||
|
| `X-RateLimit-Remaining` | Remaining requests in current window |
|
||||||
|
| `X-RateLimit-Reset` | Unix timestamp when limit resets |
|
||||||
|
|
||||||
|
### Handling Rate Limits
|
||||||
|
|
||||||
|
```python
|
||||||
|
import requests
|
||||||
|
import time
|
||||||
|
|
||||||
|
def wait_for_rate_limit_reset(response):
|
||||||
|
"""Wait until rate limit resets"""
|
||||||
|
if response.status_code == 429:
|
||||||
|
reset_time = int(response.headers.get('X-RateLimit-Reset', 0))
|
||||||
|
current_time = int(time.time())
|
||||||
|
wait_time = max(0, reset_time - current_time)
|
||||||
|
|
||||||
|
print(f"Rate limited. Waiting {wait_time}s for reset...")
|
||||||
|
time.sleep(wait_time + 1) # Add 1s buffer
|
||||||
|
return True
|
||||||
|
return False
|
||||||
|
```
|
||||||
|
|
||||||
|
### Best Practices
|
||||||
|
|
||||||
|
1. **Check remaining quota** before making requests
|
||||||
|
2. **Implement exponential backoff** for retries
|
||||||
|
3. **Cache results** to avoid duplicate requests
|
||||||
|
4. **Use batch endpoints** (when available) for multiple images
|
||||||
|
5. **Upgrade your plan** if consistently hitting limits

## Best Practices
|
||||||
|
|
||||||
|
### Performance Optimization
|
||||||
|
|
||||||
|
#### 1. Image Preprocessing
|
||||||
|
|
||||||
|
```python
|
||||||
|
from PIL import Image
|
||||||
|
|
||||||
|
def optimize_image(image_path, max_size=2048):
|
||||||
|
"""Resize large images before upload"""
|
||||||
|
img = Image.open(image_path)
|
||||||
|
|
||||||
|
# Check if resize needed
|
||||||
|
if max(img.size) > max_size:
|
||||||
|
ratio = max_size / max(img.size)
|
||||||
|
new_size = tuple(int(dim * ratio) for dim in img.size)
|
||||||
|
img = img.resize(new_size, Image.LANCZOS)
|
||||||
|
|
||||||
|
# Convert to RGB if needed
|
||||||
|
if img.mode != 'RGB':
|
||||||
|
img = img.convert('RGB')
|
||||||
|
|
||||||
|
# Save optimized
|
||||||
|
output = "optimized.jpg"
|
||||||
|
img.save(output, quality=95, optimize=True)
|
||||||
|
return output
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 2. Concurrent Processing
|
||||||
|
|
||||||
|
```python
|
||||||
|
from concurrent.futures import ThreadPoolExecutor
|
||||||
|
import requests
|
||||||
|
|
||||||
|
def process_batch(image_paths, api_key, max_workers=4):
|
||||||
|
"""Process multiple images concurrently"""
|
||||||
|
def process_one(path):
|
||||||
|
headers = {"X-API-Key": api_key}
|
||||||
|
with open(path, "rb") as f:
|
||||||
|
response = requests.post(
|
||||||
|
"https://api.iopaint.com/api/v1/remove-watermark",
|
||||||
|
headers=headers,
|
||||||
|
files={"image": f}
|
||||||
|
)
|
||||||
|
return path, response
|
||||||
|
|
||||||
|
with ThreadPoolExecutor(max_workers=max_workers) as executor:
|
||||||
|
results = list(executor.map(process_one, image_paths))
|
||||||
|
|
||||||
|
return results
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 3. Connection Reuse
|
||||||
|
|
||||||
|
```python
|
||||||
|
import requests
|
||||||
|
|
||||||
|
# Reuse session for multiple requests
|
||||||
|
session = requests.Session()
|
||||||
|
session.headers.update({"X-API-Key": api_key})
|
||||||
|
|
||||||
|
for image_path in image_paths:
|
||||||
|
with open(image_path, "rb") as f:
|
||||||
|
response = session.post(
|
||||||
|
"https://api.iopaint.com/api/v1/remove-watermark",
|
||||||
|
files={"image": f}
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Security
|
||||||
|
|
||||||
|
#### Environment Variables
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# .env file
|
||||||
|
IOPAINT_API_KEY=sk_live_1234567890abcdef
|
||||||
|
|
||||||
|
# .gitignore
|
||||||
|
.env
|
||||||
|
```
|
||||||
|
|
||||||
|
```python
|
||||||
|
import os
|
||||||
|
from dotenv import load_dotenv
|
||||||
|
|
||||||
|
load_dotenv()
|
||||||
|
api_key = os.getenv("IOPAINT_API_KEY")
|
||||||
|
```
|
||||||
|
|
||||||
|
#### API Key Rotation
|
||||||
|
|
||||||
|
```python
|
||||||
|
# Rotate keys periodically
|
||||||
|
def rotate_api_key():
|
||||||
|
old_key = os.getenv("IOPAINT_API_KEY")
|
||||||
|
new_key = generate_new_key() # From dashboard
|
||||||
|
|
||||||
|
# Test new key
|
||||||
|
test_response = requests.get(
|
||||||
|
"https://api.iopaint.com/api/v1/health",
|
||||||
|
headers={"X-API-Key": new_key}
|
||||||
|
)
|
||||||
|
|
||||||
|
if test_response.status_code == 200:
|
||||||
|
# Update environment
|
||||||
|
update_env("IOPAINT_API_KEY", new_key)
|
||||||
|
# Revoke old key from dashboard
|
||||||
|
revoke_key(old_key)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Cost Optimization
|
||||||
|
|
||||||
|
#### 1. Cache Results
|
||||||
|
|
||||||
|
```python
|
||||||
|
import hashlib
|
||||||
|
import os
|
||||||
|
|
||||||
|
def get_cached_result(image_path):
|
||||||
|
"""Check if result already cached"""
|
||||||
|
# Generate cache key from file content
|
||||||
|
with open(image_path, "rb") as f:
|
||||||
|
file_hash = hashlib.md5(f.read()).hexdigest()
|
||||||
|
|
||||||
|
cache_path = f"cache/{file_hash}.png"
|
||||||
|
if os.path.exists(cache_path):
|
||||||
|
return cache_path
|
||||||
|
return None
|
||||||
|
|
||||||
|
def process_with_cache(image_path, api_key):
|
||||||
|
"""Process with caching"""
|
||||||
|
# Check cache first
|
||||||
|
cached = get_cached_result(image_path)
|
||||||
|
if cached:
|
||||||
|
print(f"✓ Using cached result: {cached}")
|
||||||
|
return cached
|
||||||
|
|
||||||
|
# Process via API
|
||||||
|
result = remove_watermark(image_path, api_key)
|
||||||
|
|
||||||
|
# Save to cache
|
||||||
|
with open(image_path, "rb") as f:
|
||||||
|
file_hash = hashlib.md5(f.read()).hexdigest()
|
||||||
|
cache_path = f"cache/{file_hash}.png"
|
||||||
|
with open(cache_path, "wb") as f:
|
||||||
|
f.write(result)
|
||||||
|
|
||||||
|
return cache_path
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 2. Monitor Usage
|
||||||
|
|
||||||
|
```python
|
||||||
|
def check_quota_before_request(api_key):
|
||||||
|
"""Check quota before making expensive requests"""
|
||||||
|
headers = {"X-API-Key": api_key}
|
||||||
|
response = requests.get(
|
||||||
|
"https://api.iopaint.com/api/v1/stats",
|
||||||
|
headers=headers
|
||||||
|
)
|
||||||
|
|
||||||
|
stats = response.json()
|
||||||
|
quota_used = stats['total']
|
||||||
|
plan_limit = 3000 # Basic plan
|
||||||
|
|
||||||
|
remaining = plan_limit - quota_used
|
||||||
|
if remaining < 100:
|
||||||
|
print(f"⚠️ Warning: Only {remaining} requests remaining!")
|
||||||
|
|
||||||
|
return remaining > 0
|
||||||
|
```
