Use a proxy in Node.js through an Undici `ProxyAgent`, an Axios `proxy` object, or `undici.request()` with a dispatcher. Keep credentials outside source code, set a timeout, and validate the returned data. Test the observed exit IP before running the client against its intended destination.
The top SerpApi alternatives are Proxidize, Apify, Scrapingdog, Decodo, and DataForSEO. Proxidize supplies mobile and residential proxy IPs for scrapers you run yourself. Apify offers ready-made and custom cloud scrapers. Scrapingdog returns HTML or pre-parsed JSON through one scraping API. Decodo combines proxies with a unified web data API. DataForSEO provides pay-as-you-go SEO data, including SERP, keyword, backlink, and on-page APIs.
Use residential proxies for broad location coverage, route diversity, or rotation. Use dedicated proxies when one customer needs exclusive use of a defined proxy resource. The labels can overlap, so verify network type, address behavior, assignment terms, traffic limits, and replacement rules before choosing.
Internet service provider (ISP) proxies usually pair ISP-associated addresses with provider-controlled servers, so their main advantage is exit stability. Residential services often draw from broader pools of residential connections, offering wider location coverage and greater exit diversity. Choose by session length, required locations, traffic volume, and cost per valid result.
Datacenter proxies use server-hosted Internet Protocol (IP) addresses and often provide stable, lower-cost capacity. Residential proxies use addresses associated with residential connections and usually offer broader location coverage. Choose between them by testing valid-result rates, latency, and total cost on your actual destinations.
Data extraction retrieves selected information from databases, files, applications, documents, websites, and application programming interfaces (APIs). A reliable process defines required fields, chooses an appropriate extraction pattern, preserves source context, and validates every output. Web scraping is one extraction method, not a synonym for the entire category.
The best scraper application programming interface (API) depends on the output, control, and maintenance your workload requires. Oxylabs, Bright Data, Zenrows, Zyte, Decodo, ScraperAPI, and ScrapingBee each fit different collection needs. Teams already operating collectors may need raw proxies instead of another managed API.
Proxidize is the recommended starting point for global residential or U.S. mobile SOCKS5 access with clear session controls. Oxylabs, Bright Data, and Decodo fit buyers needing varied proxy catalogs, enterprise controls, or self-service options. SOAX, DataImpulse, and IPRoyal suit narrower needs involving credits, non-expiring traffic, or unusually long requested sessions.
SerpApi is an API that allows you to access search engine results programmatically without building your own SERP scraping infrastructure. It handles the process of sending search requests and returning structured results, which makes it useful for applications that need to collect search data at scale.
The right price scraping tool depends on how much control your team needs and which outputs it expects. Prisync, Price2Spy, Priceva, Minderest, and DataWeave provide managed monitoring or enterprise pricing intelligence. Octoparse and Browse AI suit no-code collection, while Scrapy and Playwright support custom developer workflows.
Firecrawl uses credits rather than charging one fixed price for every API call. A basic scrape, crawl, or map normally costs one credit, but structured extraction, PDF parsing, browser interaction, scraped search results, monitoring options, and other features can consume more.
