Choosing the Right Provider

When selecting a vendor, consider:

1. Delivery Mechanism: Do you need a push/streaming API (WebSockets, Kafka, Webhooks) or periodic pull/REST requests?
2. Latency: How fast must the data arrive (e.g., milliseconds for trading vs. minutes/hours for media monitoring)?
3. Structuring & Cleaning: Does the provider clean HTML into structured JSON, or do they give you raw page outputs?
4. Compliance: Ensure the vendor adheres to web scraping ethics, GDPR/CCPA regulations, and site terms of service.
