Need to generate hundreds or thousands of UUIDs for database seeding, batch processing, or data migration? The Bulk UUID Generator API creates multiple unique identifiers in a single efficient API call.
Why Generate UUIDs in Bulk?
When seeding databases or processing batch operations, generating UUIDs one at a time creates unnecessary network overhead. A bulk generation endpoint reduces API calls from potentially thousands to just one, dramatically improving performance.
For example, seeding 1,000 records would require 1,000 individual API calls - but with bulk generation, you get all 1,000 UUIDs in a single request.
Performance Considerations
Bulk generation offers significant advantages:
Network Efficiency
Single request/response instead of hundreds, reducing latency overhead
Rate Limit Friendly
Counts as one API call regardless of how many UUIDs are generated
Consistent Results
All UUIDs generated with identical settings in one atomic operation
Using the Bulk UUID API
TinyFn provides an efficient endpoint for bulk UUID generation:
GET https://api.tinyfn.io/v1/generate/uuid/bulk?count=100
Headers: X-API-Key: your-api-key
{
"uuids": [
"f47ac10b-58cc-4372-a567-0e02b2c3d479",
"7c9e6679-7425-40de-944b-e07fc1f90ae7",
"550e8400-e29b-41d4-a716-446655440000",
// ... 97 more UUIDs
],
"count": 100,
"version": 4
}
Parameters
| Parameter | Type | Description |
|---|---|---|
count |
integer | Number of UUIDs to generate (1-10000, default: 10) |
version |
integer | UUID version: 1 or 4 (default: 4) |
format |
string | Output format: standard, no-dashes, uppercase (default: standard) |
Code Examples
JavaScript / Node.js
const response = await fetch(
'https://api.tinyfn.io/v1/generate/uuid/bulk?count=500',
{ headers: { 'X-API-Key': 'your-api-key' } }
);
const { uuids } = await response.json();
console.log(`Generated ${uuids.length} UUIDs`);
// Use in database seeding
const records = uuids.map((id, i) => ({
id,
name: `Record ${i + 1}`
}));
Python
import requests
response = requests.get(
'https://api.tinyfn.io/v1/generate/uuid/bulk',
headers={'X-API-Key': 'your-api-key'},
params={'count': 1000, 'version': 4}
)
uuids = response.json()['uuids']
print(f"Generated {len(uuids)} UUIDs")
# Use for batch insert
records = [{'id': uuid, 'data': f'record_{i}'} for i, uuid in enumerate(uuids)]
cURL
curl "https://api.tinyfn.io/v1/generate/uuid/bulk?count=100" \
-H "X-API-Key: your-api-key"
Common Use Cases
- Database Seeding: Pre-generate IDs for test data insertion
- Batch Processing: Assign IDs to items before processing
- Data Migration: Generate new IDs when migrating between systems
- Load Testing: Create realistic data sets for performance tests
- Pre-allocation: Reserve IDs for future records
Best Practices
- Request what you need: Generate the exact count needed rather than excess
- Cache when appropriate: Store pre-generated UUIDs for immediate use
- Handle large batches: For >10,000 UUIDs, make multiple requests
- Verify uniqueness: While astronomically unlikely, validate no duplicates in critical applications
- Choose v4 for simplicity: UUID v4 is stateless and doesn't require MAC address or timestamps
