How does it work?
Debounce typing, cancel outdated requests and cache repeated results for an appropriate period. A selection should not trigger several identical queries through separate UI components.
Where can you use this API?
Use batch operations for larger collections of coordinates when available, and remember that one HTTP request may still represent many billable calculations.
What should you consider?
Measure credits per active session, set budget alerts and avoid caching data indefinitely when freshness matters.
