WHAT IS SCRAPFLY'S WEB SCRAPING API?

A web scraping API is a service that fetches any URL with anti-bot bypass, proxy rotation, and JavaScript rendering on every request, without you maintaining headless browsers or proxy stacks. Scrapfly's Web Scraping API delivers this with one HTTP call returning HTML, markdown, plain text, or structured JSON. You only pay for successful requests.

WHAT'S SCRAPFLY'S SUCCESS RATE ON PROTECTED SITES?

98% on Cloudflare, 97% on Akamai, 96% on DataDome, Imperva, and AWS WAF, 95% on PerimeterX and F5, and 94% on Kasada. Tracked daily against production traffic. See Anti-Bot Bypass for current numbers.

HOW DO YOU BYPASS ANTI-BOT PROTECTION?

Set asp=true on any request. Scrapfly detects which anti-bot system is active on the target and routes through the right engine: Curlium (byte-perfect Chrome HTTP layer for JA4 / HTTP/2 / QUIC fingerprinting) or Scrapium (stealth Chromium for JavaScript challenges, captchas, and behavioral biometrics). Both share the same Chrome identity so detection systems never see a fingerprint change mid-session. One parameter, every vendor, no per-target configuration.

WHAT KIND OF PROXIES DOES SCRAPFLY OFFER?

Two managed options. Use Scrapfly's built-in pools: datacenter (1 credit per request) or residential (25 credits per request, 190+ countries) with auto-rotation, IP cooling, and optional session stickiness. Or bring your own provider via Proxy Saver , which plugs Bright Data, Oxylabs, Webshare, SmartProxy, DataImpulse, or any SOCKS5 / HTTP proxy into the same Web Scraping API endpoint. Either way, anti-bot bypass, JA3 / JA4 fingerprint coherence, and smart retry sit on top.

DOES SCRAPFLY WORK WITH AI AGENTS AND MCP CLIENTS?

Yes. The MCP Server connects any MCP-compatible client (Claude, Cursor, Cline, Windsurf, ChatGPT, and others) to scrape, screenshot, extract, and crawl. The AI Browser Agent supports Browser Use, Stagehand, and Vibium agent loops on stealth Chromium. Native integrations also exist for LangChain, LlamaIndex, and CrewAI.

WHAT OUTPUT FORMATS DOES SCRAPFLY SUPPORT?

Multiple formats from a single API call: HTML (raw or sanitized), Markdown (with link / image stripping for LLM contexts), plain text, JSON (parsed or as the API envelope), screenshots in PNG / JPEG / WebP via the Screenshot API , structured JSON via the Extraction API using LLM prompts, CSS / XPath rules, or pre-trained models, and WARC archives for crawl jobs .

WHICH PROGRAMMING LANGUAGES DOES SCRAPFLY SUPPORT?

Five official SDKs : Python , TypeScript (Node, Deno, Bun), Go , Rust , and a Scrapy extension. The REST API works with any language via plain HTTP. The CLI handles shell pipelines and CI integration.

HOW IS SCRAPFLY DIFFERENT FROM BRIGHT DATA, ZYTE, AND OXYLABS?

Bright Data and Oxylabs are proxy-first platforms with scrapers built on top: strong on proxy infrastructure and managed datasets, heavier configuration per target. Zyte is built around Scrapy and managed services for high-protection enterprise targets. Scrapfly is single-endpoint: one API call with asp=true handles anti-bot, proxy rotation, JavaScript rendering, and structured output across every vendor with no per-target setup. You pay only for successful requests. See per-vendor comparisons on the comparison hub .
