Data Acquisition Strategies

Your strategy for data acquisition depends on your model’s needs. Choose the method that best fits your use case, from foundational training to specialized, real-time data collection.

Web Archive

Best for: Foundational, large-scale model training.

The Web Archive provides access to a petabyte-scale repository of historical web data, making it the ideal source for training large language and diffusion models that require a comprehensive understanding of the digital world.

• Use Case: Pre-training LLMs, historical analysis, building base models.
• Next Step: Contact our data experts for access and pricing.
• Learn More: Web Archive Documentation

Pre-collected Datasets

Best for: Fine-tuning models on specific domains.

Our curated datasets provide structured, high-quality data across numerous industries, allowing you to efficiently specialize your model for specific tasks without the overhead of data collection.

• Use Case: Fine-tuning, industry-specific models, market research.
• Pricing: Starts from $250 per 100,000 records.
• Quality: Rigorously validated. Free samples are available for evaluation.
• Next Step: Explore Datasets

Custom Collection

Best for: Fresh, on-demand data from specific sources.

Initiate programmatic data collection jobs to get real-time, structured data from any public URL. This gives you complete control over the freshness and specificity of your training data.

• Use Case: Real-time applications, tracking dynamic data, custom knowledge bases.
• Pricing: Based on the complexity and scale of the request.
• Next Step: Contact us for a custom quote.
• Learn More: Custom Dataset API Documentation

API Example:

curl "https://api.brightdata.com/datasets/initiate?dataset_id=YOUR_DATASET_ID&type=url_collection&view=YOUR_VIEW_ID" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '[{"url":"https://example.com"}]'

Video & Media

Best for: Training multimodal models at scale.

Overcome the limitations of tools like yt-dlp by using our resilient infrastructure. The Web Unlocker API handles rate limits, geo-restrictions, and bot detection to ensure a reliable video data pipeline.

• Use Case: Training video, audio, and image models.
• KYC Required: Access requires a Know Your Customer process to ensure ethical and compliant data sourcing due to the sensitive nature of media content.
• Next Step: Book a meeting with our data experts to begin the approval process.
• API Reference: Media Data API, download video, audio, captions, thumbnails, and storyboards from YouTube, Vimeo, TikTok, and Bilibili.
