Questions & Answers

As answered by people managing Diffbot and useString.ai.

What's the story behind your product?

useString.ai's answer:

String is a New York company building web-data infrastructure, turning the messy public web into accurate, usable data. Web Access is the part that actually gets pages back from sites that block other tools. It’s available as a standalone API and a hosted MCP server.

What makes your product unique?

useString.ai's answer:

It gets through sites that block other scrapers and only bills requests that succeed. In an open benchmark of 17 scraping APIs on 100 bot-protected sites, String had the highest success rate at 98.6%, and the method and raw data are public. It picks the proxy and rendering method for each page itself, so developers don’t manage proxies or retries.

Why should a person choose your product over its competitors?

useString.ai's answer:

The best reason is reliability on hard sites: highest success rate in our open benchmark, and blocked requests aren’t billed. There’s nothing to configure, since proxies, rendering and captcha handling are chosen automatically. It returns clean Markdown, HTML or JSON, also offers web search and site mapping, and has a hosted MCP server for agents in Claude and Cursor. Pricing is public, and new accounts get $5 of free credit (about 20,000 fetches), no card needed.

How would you describe the primary audience of your product?

useString.ai's answer:

Developers and data teams building AI agents, data products and pipelines that need live web data, especially from sites with strong bot protection. Typical uses are alternative data, pricing and inventory monitoring, talent and job data, real estate listings, and giving AI agents web access.

Which are the primary technologies used for building your product?

useString.ai's answer:

The service runs on managed cloud browsers and a proxy network, with automatic routing per request. The MCP server is open source and written in TypeScript. It exposes a REST API and an MCP endpoint, with SDK-free access from curl, Python and Node.

Who are some of the biggest customers of your product?

useString.ai's answer:

YipitData Revelio Labs DataWeave Sachem Head Canary Data Pararius Appsmith
