PageSightCaching Best Practices
Learn how to optimize your API usage with effective caching strategies.
Why Caching Matters
Benefits of Caching
- • Cost Efficiency: Reduce API calls and associated costs
- • Performance: Faster response times for cached data
- • Reliability: Less dependency on external website availability
- • Rate Limits: Stay within your rate limits more easily
Free Tier Strategies
Working with 1-Day Cache
✅ Do
- • Plan your requests around the 1-day cache window
- • Batch requests for URLs you need to check
- • Store cached responses locally if possible
- • Check cache status headers to avoid unnecessary requests
❌ Don't
- • Make repeated requests for the same URL within 24 hours
- • Ignore the X-Cache header
- • Assume every request triggers a fresh scrape
Premium Tier Strategies
Optimizing Custom Cache
Choosing Cache Duration
- Static Content (5-15 minutes): For content that rarely changes
- Dynamic Content (30-60 minutes): For content that updates periodically
- Frequently Updated (2-6 hours): For content that changes often
- Rarely Updated (12-24 hours): For stable content
Example: Short Cache for News Sites
Loading code...
News sites update frequently, so a 10-minute cache is appropriate.
Example: Long Cache for Documentation
Loading code...
Documentation sites change infrequently, so a 24-hour cache works well.
Revalidation Guidelines
When to Revalidate
- • User explicitly requests fresh data
- • You know content was recently updated
- • Debugging scraping issues
- • Testing website changes
When NOT to Revalidate
- • On every API call
- • In automated background jobs
- • For high-frequency requests
- • Without user consent

Pro Tips
Optimization Tips
- Monitor your cache hit rate to optimize cache duration
- Use shorter cache times for frequently changing content
- Implement local caching in your application for additional savings
- Track X-Cache headers to understand cache behavior
- Consider your use case when choosing between cache duration and revalidation
