Check Stock Availability +Ensure sufficient stock before committing to a design. + +```python +# Only use parts with >1000 stock +high_stock = [p for p in results if p['stock'] > 1000] +``` + +### 3. Compare Prices +Even within Basic library, prices vary significantly. + +```python +# Find cheapest option +cheapest = min(results, key=lambda x: x.get('price1', 999)) +``` + +### 4. Use Standardized Packages +Stick to common packages (0402, 0603, 0805) for better availability and pricing. + +### 5. Cache Database Locally +Download the full parts database once and search locally for faster results. + +```python +# Initial download (one-time, ~5-10 minutes) +if not os.path.exists("data/jlcpcb_parts.db"): + parts = client.download_all_components() + db.import_jlcsearch_parts(parts) + +# Subsequent searches use local database (instant) +results = db.search_parts(...) +``` + +## Troubleshooting + +### API Rate Limiting +JLCSearch is a community service.
