# QuantumProxies > Residential, mobile, ISP and datacenter proxies, plus a Scraper API for web > pages, SERP and structured extraction. Real browser TLS fingerprints, geo > targeting down to city level, and parsers that repair themselves. ## Docs - [Scraper API reference](https://app.quantumproxies.io/docs/scraper-api.md): every endpoint, parameter and example for scraping, SERP, crawling, parser generation and the web unlocker - [Public API (OpenAPI 3.0)](https://app.quantumproxies.io/api-docs.json): proxy plans, orders, proxy generation, IP whitelisting, geo targeting options - [Postman collection](https://app.quantumproxies.io/docs/quantumproxies.postman_collection.json): importable requests for the whole API ## Key capabilities - Scrape a page to Markdown with one call; escalate to a real browser only when the target blocks - Generate a CSS parser from a plain-language field list, then replay it with zero AI cost - Parser presets that score themselves per field and regenerate when a site redesigns - Capture an SPA's own JSON API instead of scraping its DOM (`xhr`, `fetchResource`) - Parsed Google/Bing/DuckDuckGo results across 18 verticals, including AI Overviews - A web unlocker usable as a forward proxy, a direct request, or a JSON job ## Getting started - [Sign up](https://quantumproxies.io): get an API key (`qp_live_…`) - Auth: `Authorization: Bearer ` against `https://app.quantumproxies.io/api/v1`
