Rate Limiting & Quotas - MemoryLake AI

Rate Limit Overview

API requests are rate limited to ensure fair usage and system stability. Limits are enforced at two levels: per IP address and per user account.

Current Limits

Dimension	Limit
Per IP address	Sliding window of several minutes; the exact threshold is set per deployment and is generous for normal integration traffic
Per user account	600 requests / minute on the default access group
Per IP address, upload endpoints	Separate, tighter per-minute bucket

When either limit is exceeded, the API returns HTTP status 429 Too Many Requests with a Retry-After header. The per-account limit is set by your access group, so it may differ from the default shown above — contact support for higher limits.

Rate Limit Exceeded Response

When a rate limit is exceeded, the API responds with:

{
  "success": false,
  "message": "Rate limit exceeded. Please retry later.",
  "error_code": "RATE_LIMIT_EXCEEDED"
}

Handling Rate Limits

Implement Exponential Backoff

async function apiRequestWithBackoff(url, options, maxRetries = 3) {
  for (let i = 0; i < maxRetries; i++) {
    const response = await fetch(url, options);

    if (response.status === 429) {
      const waitTime = Math.pow(2, i) * 1000;
      console.log(`Rate limited. Retrying in ${waitTime}ms...`);
      await sleep(waitTime);
      continue;
    }

    return response;
  }

  throw new Error('Max retries exceeded due to rate limiting');
}

Best Practices

Implement exponential backoff with jitter for retries
Cache responses when possible to reduce redundant requests
Batch operations where supported (e.g. batch document removal)
Implement client-side request queuing to smooth out traffic spikes
Monitor request volume and log 429 responses for observability

Storage and Resource Quotas

Resource	Limit
Projects	Unlimited
Memories per project	Unlimited
Documents per project	Unlimited
Total storage	Depends on your plan
Max file size	Depends on your plan; large files upload via multipart automatically

Storage allowances are tied to your subscription. Check Billing in the console for your current plan, or contact support if you expect unusually large uploads.
