Choosing the right endpointLink to Choosing the right endpoint

Piloterr exposes three complementary ways to fetch a public web page. Pick the lightest engine that works for your target site.

Endpoint Engine Credits Use when
Website Crawler HTTP request (no JavaScript) 1 The HTML you need is already in the first response: blogs, docs, server-rendered catalog pages, sitemaps.
Website Rendering Headless browser (JavaScript executed) 2 Content appears only after JS runs: React/Vue/Angular SPAs, lazy-loaded listings, pages that need wait_for or POST browser_instructions.
Website WebUnlocker Browser + unlock stack 3 Website Rendering or Website Crawler hit bot walls (Cloudflare, DataDome, Akamai, PerimeterX) and the domain is on Piloterr's approved whitelist.

Decision flow

  1. Try Crawler first if you do not need client-side rendering. It is the fastest and cheapest option.
  2. Switch to Rendering when the DOM is empty, prices load asynchronously, or you must wait for a selector / run browser steps.
  3. Escalate to WebUnlocker only for hardened retail or marketplace domains that block normal browser traffic. Whitelist approval is required before production use.

Website WebUnlocker is the hardest tier of the website stack. It combines headless rendering with an unlock layer tuned for enterprise bot managers. Use it when:

Whitelist required: the target hostname must be approved on Piloterr's approved whitelist before production traffic. Contact Piloterr support to request new domains.

Beta: behavior and supported domains may evolve.

NotesLink to Notes

  • Do not start with WebUnlocker: validate Crawler and Rendering first to save credits.
  • Whitelist is per domain; subdomains may require separate approval.
  • For standard JS rendering without whitelist, use Website Rendering instead.

Main use casesLink to Main use cases

  • Product and listing pages on DataDome or Akamai-protected retailers
  • Automotive and home-improvement marketplaces on approved domains
  • Pipelines where Rendering consistently returns challenge pages
  • Competitive price monitoring on hardened e-commerce sites
