Overview

AI-generated overview

WebLens is a paid, pay-per-call web scraping and search service that lets an assistant fetch, crawl, search and extract web content without an account or API…

What you can do
  • Fetch pages as clean markdown, with optional headless-browser rendering, automatic fallback and screenshots
  • Bulk-fetch up to 20 URLs, map a site's URLs, crawl a site within depth and page limits, and extract PDF text
  • Run Google-backed searches for web, news, images, places, shopping, scholar, autocomplete and trends
  • Pull YouTube transcripts and Hacker News discussion aggregates
  • Extract schema-defined structured data and get cited answers or multi-step deep research
  • Look up domain, package, tech-stack and company profiles, plus off-chain project due diligence
When to use it
Useful when an assistant needs live web content, search results or site-level research and you would rather pay per call than manage scraping infrastructure or API keys. It suits one-off research, competitive and vendor checks, and bulk page collection.
Requirements
A remote streamable HTTP endpoint; no account or API key is declared. Calls are paid in USDC per request, with prices listed per tool and a minimum x402 payment of about $0.004. A wallet or payment client capable of x402 payments is needed for paid calls; some endpoints offer free previews.
Before you install
Every call costs money in USDC, and some tools charge up to 3x on bot-protected or complex sites, so costs can add up quickly. Payment is made from your wallet via x402, so treat wallet access as sensitive. Requested URLs and queries are sent to a third-party service and on to upstream providers such as Google. Crawling and fetching act on external sites; robots.txt is honoured by default for crawling.

Installation

In SourceWeft

  1. Open WebLens in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.weblens%2Fweblens/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

preview_endpoint

FREE. See what a paid WebLens endpoint costs and what it returns before paying: the live price, a one-line summary, and a recorded sample of the exact response shape. Endpoints with no paid upstream (/fetch/basic, /contents, /map) also run a real truncated LIVE preview when you pass a url; SerpAPI- and Anthropic-backed endpoints return the recorded sample only, because free live runs there would burn upstream credits. Price: free
