Ai Summarizer X402 is an MCP server that summarizes raw text or any web URL into concise key points, providing compression ratio, reading-time metrics, and extracted takeaways. It uses the x402 micropayment protocol (USDC on Base L2) for per-call billing—no API key or signup is required. The server is part of the klymax402 marketplace, offering 100 x402 micropayment APIs for AI agents.
Configure the MCP client with the server URL https://ai-summarizer.api.klymax402.com/mcp. Two tools are available: ai_summarize_text (POST, $0.01 per call) accepts text and optional maxLength; ai_summarize_url (GET, $0.015 per call) accepts url and optional maxLength. Any x402-aware client (e.g., @x402/fetch, x402-agent-tools, ATXP) automatically handles the payment challenge cycle.

No special runtime beyond an x402-aware client. The MCP configuration is a simple JSON entry. For HTTP access, any tool that can handle the 402 Payment Required challenge and retry cycle works.
The README does not specify data storage or privacy details. All summarization happens per-request; payment is per-call.
Each call costs a fixed micropayment ($0.01 for text, $0.015 for URL). The server is not designed for full content extraction, SEO analysis, screenshot capture, or sentiment analysis—separate klymax402 APIs handle those.
Transport is HTTP via MCP (WebSocket-based) or direct REST (`/api/summarize`). Authentication is handled entirely by the x402 payment challenge; no API keys or tokens are needed.
