Rate Limits

ArchiCore API implements rate limiting to ensure fair usage.

Limits by Tier

Tier	Requests/day	Requests/minute	Projects
Free	100	10	3
Pro	10,000	100	25
Enterprise	Unlimited	1,000	Unlimited

Rate Limit Headers

Every API response includes rate limit information:

HTTP/1.1 200 OK
X-RateLimit-Limit: 100
X-RateLimit-Remaining: 95
X-RateLimit-Reset: 1640000000

Header	Description
X-RateLimit-Limit	Maximum requests allowed
X-RateLimit-Remaining	Requests remaining in window
X-RateLimit-Reset	Unix timestamp when limit resets

Rate Limit Exceeded

When you exceed the rate limit:

HTTP/1.1 429 Too Many Requests
Retry-After: 60

{
  "success": false,
  "error": "Rate limit exceeded",
  "code": "RATE_LIMIT_EXCEEDED",
  "retryAfter": 60
}

Best Practices

1. Check Headers

Always check X-RateLimit-Remaining before making requests:

async function makeRequest(url) {
  const response = await fetch(url, { headers });

  const remaining = response.headers.get('X-RateLimit-Remaining');
  if (parseInt(remaining) < 10) {
    console.warn('Rate limit running low:', remaining);
  }

  return response.json();
}

2. Implement Exponential Backoff

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

    if (response.status !== 429) {
      return response.json();
    }

    const retryAfter = response.headers.get('Retry-After') || 60;
    await sleep(retryAfter * 1000 * Math.pow(2, i));
  }

  throw new Error('Max retries exceeded');
}

3. Cache Responses

Cache responses to reduce API calls:

const cache = new Map();

async function getCached(key, fetchFn, ttl = 60000) {
  const cached = cache.get(key);
  if (cached && Date.now() - cached.timestamp < ttl) {
    return cached.data;
  }

  const data = await fetchFn();
  cache.set(key, { data, timestamp: Date.now() });
  return data;
}

4. Batch Operations

Use batch endpoints when available:

// Instead of multiple requests
for (const id of projectIds) {
  await client.projects.get(id);  // ❌ Multiple requests
}

// Use batch endpoint
await client.projects.getBatch(projectIds);  // ✓ Single request
