Lovable App Hitting API Rate Limits

Quick Answer

Your app is making too many requests to an external API. This commonly happens with search inputs that fire a request on every keystroke. Start with "Add debouncing and caching" before making broader code changes.

You're in the right place if...

!External API returns 429 Too Many Requests
!App works briefly then stops
!Error: rate limit exceeded

Why this happens

Your app is making too many requests to an external API. This commonly happens with search inputs that fire a request on every keystroke.

Fix

Add debouncing and caching

Tell Lovable to add proper API management:

Copy this prompt

The app is hitting rate limits on external API calls. Please add:
1. Request debouncing for search inputs (300ms delay)
2. Response caching with a 5-minute TTL
3. Error handling that shows a friendly message when rate limited
4. Exponential backoff for retried requests

Prevent this next time

Always debounce search inputs and cache API responses. Include this in your founding prompt when using external APIs.

Frequently Asked Questions

Waiting a short time (e.g. 300ms) after the user stops typing before making the API call. This prevents firing 20 requests while someone types a search query.

Saving API responses temporarily. If the same data is requested again within 5 minutes, serve the saved version instead of hitting the API again.
