A look at usestring.ai

String is a web scraping API designed for AI agents, developers, and data teams. It handles anti-bot systems like Cloudflare, DataDome, PerimeterX, Akamai, Kasada, and CAPTCHA automatically, returning pages as clean Markdown, HTML, or JSON with no proxy management needed. Each request escalates intelligently from lightweight fetches to full browser rendering and premium proxies based on what the target requires. The service achieved 98.6% success on the open Web Data Frontier Benchmark across 100 hard-to-scrape sites. It supports AI agents through MCP protocol integration with Claude, ChatGPT, Cursor, and Perplexity, enabling agents to fetch any page as a single tool call. Pricing is based on successful requests only, with blocked requests costing nothing.

FAQ

What is the Web Access API?
A web scraping API for humans and agents. One HTTP call against any URL returns the page as clean content, fully rendered and past whatever anti-bot is sitting in front of it. You only pay when it comes back.
Which anti-bot systems does it get through?
Cloudflare, DataDome, PerimeterX, Akamai, Kasada, and CAPTCHA challenges. Every request escalates automatically: lightweight fetches, full browser rendering, premium proxies, geolocated routing, and CAPTCHA solving, which compliance-sensitive teams can switch off per request.
How reliable is it?
String passed 98.6% of requests in the open-source Web Data Frontier Benchmark, achieving the best success rate of any provider tested across 100 hard targets with 500 requests per provider, with the benchmark repeating monthly.
How much does it cost?
Start with 20,000 free standard fetches with no card needed. After that, plans start at $19/month with the fee added as usage credit billed per successful request. Blocked requests cost nothing.
Can my agent use it?
Yes. Add String over MCP and your agent fetches any page as a single tool call in Claude, ChatGPT, Cursor, Perplexity, or anything that speaks the MCP protocol.
