Part of the klymax402 marketplace -- 100 x402 micropayment APIs for AI agents, one wallet, USDC on Base.

Quickstart -- MCP

Add to your MCP client config (Claude Desktop, Cursor, ElizaOS, etc.):

{
  "mcpServers": {
    "web-scraper": {
      "url": "https://web-scraper.api.klymax402.com/mcp"
    }
  }
}

Quickstart -- HTTP (x402)

curl "https://web-scraper.api.klymax402.com/api/scrape?url=https://example.com"
# -> 402 Payment Required, with an x402 payment challenge in the response body

Any x402-aware client (@x402/fetch, x402-agent-tools, ATXP) handles the 402 -> sign -> retry cycle automatically.

Tools

web_scrape_to_markdown

Scrape and extract content from a URL with full JS rendering, returned as clean markdown. Alternative to Firecrawl scrape at 2.5x lower cost. Strips navigation, ads, scripts, and boilerplate — ideal for RAG pipelines and AI research agents.

Parameters

Example response:

{"title":"How to Scale APIs","description":"A guide to...","content":"# How to Scale APIs\n\nScaling requires...","wordCount":1250,"charCount":7800,"url":"https://blog.example.com/scale-apis"}

When to use: summarizing articles, building RAG corpora, researching topics from web sources, or extracting data from documentation pages. Essential for any workflow that needs to scrape and extract content from web pages as LLM input. Drop-in replacement for Firecrawl scrape.

Not for: screenshots (use capture_screenshot), SEO audit (use seo_audit_page), tech stack detection (use website_detect_tech_stack), web search (use web_search_query).

web_scrape_batch

Use this when you need to extract clean content from multiple web pages at once (up to 10 URLs). Returns the same structured markdown output as web_scrape_to_markdown for each URL.

Parameters

Example response:

{"results":[{"url":"https://a.com","title":"Page A","wordCount":800},{"url":"https://b.com","title":"Page B","wordCount":1200}],"summary":{"total":2,"totalWords":2000,"failed":0}}

When to use: building research corpora, comparing content across competitor pages, or bulk documentation extraction. Essential when you have 3+ URLs to process in one workflow.

Not for: single URLs (use web_scrape_to_markdown), SEO comparison (use seo_audit_batch).
