Web Access API

🎯 What is String Web Access?

One endpoint for any URL. Send a request, get back rendered HTML or clean markdown — no browser fleet to run, no proxy pool to babysit, no retry logic to write.

Built for web scraping, price and inventory monitoring, market research, and feeding live web data to LLM pipelines and agents.

📊 Benchmarked, not claimed

We publish an open benchmark against 14 other providers — 99 hard targets, 495 requests each, re-run monthly. We come out top at 97.0% success.

Search "web data frontier benchmark" on GitHub and run it yourself.

✨ Features

• ✅ Rotating residential proxies — geo-targeting supported
• ✅ Challenge handling — [Cloudflare, DataDome, PerimeterX, Kasada]
• ✅ Automatic retries — you pay for successes, not attempts [if true]

🔌 MCP server

We ship a hosted MCP server, so Claude, Cursor, and any other MCP client can fetch and search the web directly — no glue code, no scraper to maintain.

Point your client at our MCP endpoint and you get:

• ✅ fetch — any URL to clean markdown, ready for a context window
• ✅ search — web search with full page content, not just snippets
• ✅ sitemap — crawl a site and map its URLs
