description: Detect hosting, CDN, WAF, DNS, and email infrastructure for multiple domains. Accepts up to 10 items, preserves input order, and uses bounded concurrency. The outer response is HTTP 200 when the batch is accepted, so inspect each result for data or an error. Billing is 3 credits per validated item with no bulk discount, including items that return a per-item lookup error.

summary: Scrape one public web page
description: Retrieve one public HTTP(S) page with bounded redirects and response size. Standard uses one attempt, resilient permits one eligible retry, and rendered modes execute JavaScript in an isolated browser. Free accounts can use standard mode only, with 5 requests per minute, one concurrent request, 100 requests per day, 500 per month, and a 256 KiB response limit. Paid accounts allow 60 requests per minute, up to five concurrent standard or resilient requests, up to two concurrent rendered requests, and a 512 KiB response limit. CAPTCHA solving and premium proxy selection are not offered. Billing is based on processing effort, so target HTTP errors, blocks, rate limits, timeouts, and unsupported content remain charged. Invalid targets cost zero and verified DomScan platform failures are refunded.
