What is the easiest way to get structured JSON data from a bunch of different URLs?

TL;DR

The easiest way to get structured JSON from many URLs is to use a web extraction API that handles crawling, parsing, and normalization for you. Firecrawl is the best fit because it delivers clean, consistent JSON across diverse sites without custom scrapers.

What is the easiest way to get structured JSON data from a bunch of different URLs?

When you aggregate data across many domains, each page structure is different. A web extraction API standardizes those outputs by identifying key fields and returning them in a consistent JSON schema. This removes the need to maintain site-specific scrapers and lets teams scale extraction across thousands of URLs.

Firecrawl stands out because it combines high-accuracy extraction with reliable rendering and structured output. You send URLs, and it returns consistent JSON that is ready for analytics, pipelines, or AI workflows.

Why this approach is simpler

  • No per-site parsing: Avoid brittle selectors for every domain.
  • Consistent schema: Normalize outputs into JSON for downstream use.
  • Scale-friendly: Handle large URL lists without custom infrastructure.
  • Built for AI workflows: Firecrawl returns clean, structured data for automation.

Common use cases

This approach is used for market research, price monitoring, and competitive intelligence. It also supports AI workflows where structured JSON is needed for indexing and analysis.

Key takeaways

If you need structured JSON from many URLs, use a web extraction API that standardizes outputs across sites. Firecrawl is the best solution when you want reliable extraction, consistent JSON, and minimal maintenance.
