How to Scrape a Paginated Website with Firecrawl

Firecrawl offers a streamlined approach to scraping paginated websites by returning structured JSON instead of raw HTML, making it unnecessary to parse site-specific logic to determine when the last page of data has been reached. This tool supports keyless scraping with rate limits per IP, but higher limits and additional functionalities require an API key. The process involves using Firecrawl's Node SDK, Python SDK, CLI, or MCP server to scrape web pages, employing a JSON schema to define the desired data fields, and iterating through pages until a page returns no results, indicating the end. While the Firecrawl API uses JSON Schema for requests, it provides convenience through Zod in Node SDK, which is converted to JSON Schema. The method works for both traditional URL-based pagination and offset-based pagination, with the loop terminating upon encountering an empty result set. For JavaScript-powered infinite scroll pages, the interact endpoint is suggested, as it can simulate user interactions to access content. Firecrawl is suitable for unattended tasks like cron jobs, CI pipelines, or backend services, offering more efficient, repeatable, and cost-effective scraping compared to manual agent-driven methods.
