# Evernote Rate Limits ## Overview Evernote enforces rate limits per API key, per user. When exceeded, the API throws `EDAMSystemException` with `errorCode: RATE_LIMIT_REACHED` and `rateLimitDuration` (seconds to wait). Production integrations must handle this gracefully. ## Prerequisites - Evernote SDK setup - Understanding of async/await patterns - Error handling implementation ## Instructions ### Step 1: Rate Limit Handler Catch `EDAMSystemException` and check for `rateLimitDuration`. Implement exponential backoff: wait the specified duration, then retry. Track retry attempts to avoid infinite loops. ```javascript async function withRateLimitRetry(operation, maxRetries = 3) { for (let attempt = 0; attempt < maxRetries; attempt++) { try { return await operation(); } catch (error) { if (error.rateLimitDuration && attempt < maxRetries - 1) { const waitMs = error.rateLimitDuration * 1000; console.log(`Rate limited. Waiting ${error.rateLimitDuration}s...`); await new Promise(r => setTimeout(r, waitMs)); continue; } throw error; } } } ``` ### Step 2: Rate-Limited Client Wrapper Wrap the NoteStore with a class that adds configurable delays between API calls. Use a request queue to prevent bursts. Track request timestamps for monitoring. ```javascript class RateLimitedClient { constructor(noteStore, minDelayMs = 100) { this.noteStore = noteStore; this.minDelayMs = minDelayMs; this.lastRe...
