# Bright Data Rate Limits

## Overview

Handle Bright Data rate limits and concurrent request limits. Unlike traditional API rate limits, Bright Data limits are per-zone and based on concurrent connections and requests per second. The Web Scraper API trigger endpoint is limited to 20 requests/min and 60 requests/hour.

## Prerequisites

- Bright Data zone configured
- Understanding of async/await patterns
- p-queue or similar concurrency library

## Instructions

### Step 1: Understand Bright Data Rate Limits

| Product | Concurrent Limit | Per-Minute | Notes |
|---------|-----------------|------------|-------|
| Residential Proxy | Based on plan | No hard cap | Charged per GB |
| Web Unlocker | Based on plan | No hard cap | Charged per request |
| Scraping Browser | Based on plan sessions | No hard cap | Charged per session |
| SERP API | Based on plan | No hard cap | Charged per search |
| Web Scraper API (trigger) | N/A | 20/min, 60/hr | Async collections |
| Datasets API | N/A | 20/min | Snapshot requests |

### Step 2: Implement Concurrent Request Limiter

```typescript
// src/brightdata/limiter.ts
import PQueue from 'p-queue';

// Match concurrency to your Bright Data plan limits
const scrapeQueue = new PQueue({
  concurrency: 10,       // Max concurrent proxy requests
  interval: 1000,        // Per second
  intervalCap: 20,       // Max 20 requests per second
  timeout: 120000,       // Kill after 2 min
  throwOnTimeout: true,
});

export async function queuedScrape(url: string): Promise<string> {
  return scrapeQueue.add(async () => {
    const client = getBrightDataClient();
    const response = await client.get(url);
    return response.data;
  });
}

// Monitor queue health
scrapeQueue.on('active', () => {
  console.log(`Queue: ${scrapeQueue.size} waiting, ${scrapeQueue.pending} active`);
});
```

### Step 3: Exponential Backoff for Proxy Errors

```typescript
// src/brightdata/backoff.ts
export async function scrapeWithBackoff(
  url: string,
  config = { maxRetries: 5, baseDelay: 2000, maxDelay: 60000 }
): Promise<string> {
  for (let attempt = 0; attempt <= config.maxRetries; attempt++) {
    try {
      const client = getBrightDataClient();
      const response = await client.get(url);
      return response.data;
    } catch (error: any) {
      const status = error.response?.status;
      const luminatiError = error.response?.headers?.['x-luminati-error'];

// Only retry on transient errors
      const retryable = [502, 503, 429].includes(status)
        || error.code === 'ETIMEDOUT'
        || luminatiError === 'ip_banned';

if (attempt === config.maxRetries || !retryable) throw error;

### Step 4: Web Scraper API Rate Limiter

```typescript
// src/brightdata/trigger-limiter.ts — 20/min, 60/hr for trigger endpoint
const triggerQueue = new PQueue({
  concurrency: 1,
  interval: 60000,       // Per minute
  intervalCap: 20,       // 20 triggers per minute
});

let hourlyCount = 0;
setInterval(() => { hourlyCount = 0; }, 3600000); // Reset hourly

export async function rateLimitedTrigger(
  datasetId: string,
  urls: string[]
): Promise<any> {
  if (hourlyCount >= 55) { // Leave buffer
    throw new Error('Approaching hourly trigger limit (60/hr). Wait before triggering.');
  }

return triggerQueue.add(async () => {
    hourlyCount++;
    const response = await fetch(
      `https://api.brightdata.com/datasets/v3/trigger?dataset_id=${datasetId}&format=json`,
      {
        method: 'POST',
        headers: {
          'Authorization': `Bearer ${process.env.BRIGHTDATA_API_TOKEN}`,
          'Content-Type': 'application/json',
        },
        body: JSON.stringify(urls.map(url => ({ url }))),
      }
    );
    return response.json();
  });
}
```

### Step 5: Batch URLs to Minimize Triggers

```typescript
// Instead of triggering per-URL, batch into single triggers
async function batchTrigger(urls: string[], batchSize = 100) {
  const batches = [];
  for (let i = 0; i < urls.length; i += batchSize) {
    batches.push(urls.slice(i, i + batchSize));
  }

console.log(`Triggering ${urls.length} URLs in ${batches.length} batches`);

for (const batch of batches) {
    await rateLimitedTrigger('gd_dataset_id', batch);
  }
}
```

## Output

- Concurrent request limiter matching plan limits
- Exponential backoff handling X-Luminati error headers
- Web Scraper API trigger rate limiter (20/min, 60/hr)
- URL batching to minimize trigger count

## Error Handling

| Signal | Meaning | Action |
|--------|---------|--------|
| HTTP 429 | Concurrent limit exceeded | Queue requests with p-queue |
| HTTP 502 + `ip_banned` | IP blocked by target | Retry (auto-rotates IP) |
| HTTP 502 + `target_site_blocked` | Anti-bot blocked | Switch to Scraping Browser |
| `ETIMEDOUT` | Connection timeout | Retry with longer timeout |
| Hourly trigger limit | 60 triggers/hr exceeded | Batch URLs into fewer triggers |
