Overview

Agent402.Tools — pay-per-call web tools exposes live web search, cited answers, JavaScript page rendering, news, stock quotes, transcription, memory, and agent workflow tools through MCP. Calls are paid individually with USDC through x402 or MPP when a wallet is configured, while eligible pure-CPU tools can use proof-of-work. Its catalog and routing tools can discover and invoke hundreds of additional Agent402 tools and external x402 sellers. Reach for it when an agent needs current web data, paid specialist APIs, or multi-step tool selection without integrating each provider separately.

Use cases

  • Search the live web for pages published after a model's training cutoff
  • Render JavaScript-heavy pages and extract their readable content
  • Retrieve cited answers or current news for research workflows
  • Transcribe remote audio with optional speaker labels
  • Discover and run paid tools across the Agent402 and x402 ecosystems

Key features

  • Live search, news, and cited answer tools
  • Headless Chromium rendering for JavaScript-heavy pages
  • End-of-day US equity quotes and remote audio transcription
  • Wallet-scoped persistent key-value memory
  • Catalog discovery, workflow planning, and external x402 routing
  • x402, MPP, and proof-of-work payment paths

How Agent402.Tools — pay Per Call web tools works

What Agent402.Tools — pay-per-call web tools does

Agent402.Tools provides an MCP front door to a collection of metered services. Its flagship tools cover live web search, synthesized answers with citations, recent news, headless-browser rendering, US equity quotes, audio transcription, wallet-scoped memory, and decision planning. Additional catalog tools expose hundreds of pay-per-call services, while routing can find and purchase tools from external x402 sellers.

The service is useful for agents that need information beyond their model's training data or need to call specialized APIs on demand. Search results, rendered pages, and routed third-party responses are labeled as external or untrusted content where applicable, so the calling agent should treat them as data rather than instructions.

How it works

The MCP endpoint can run through the hosted service at https://agent402.tools/mcp or through the npm package. Paid calls use x402 or MPP payment flows, generally with USDC and a configured wallet. The payment tools report how the server is configured, and catalog.call handles payment for catalog tools automatically when a wallet key is available. Eligible pure-CPU services may instead be available through proof-of-work.

The main discovery path is to use web.search for pages, web.news for current events, or catalog.find and catalog.search for longer-tail services. decide.plan can assemble a multi-step plan with parameters, fallbacks, and cost estimates; decide.execute runs that plan within its budget. router.execute extends this model to proven external x402 sellers.

Setup and configuration

A local stdio installation can be added with:

Terminal
claude mcp add agent402 -- npx -y agent402-mcp@latest

Clients can also connect to the hosted MCP URL directly. Setup guidance is available for Claude Code, Cursor, VS Code, Windsurf, Cline, Roo Code, Codex CLI, Gemini CLI, and Continue. A wallet key is needed for wallet-funded features such as live search, answer generation, browser rendering, transcription, memory, stock quotes, and the hosted LLM gateway. The server can run its free tier without a wallet.

Tools and capabilities

  • web.search returns ranked live pages with titles, URLs, snippets, dates, and optional freshness filters.
  • web.answer produces a cited synthesis from live search results.
  • web.news returns recent articles with publisher and breaking-news fields.
  • browser.render executes JavaScript in headless Chromium and extracts page content as Markdown; screenshot is available through the catalog for visual evidence.
  • market.quote supplies end-of-day US equity data, including close, range, volume, and change.
  • audio.transcribe accepts a remote audio URL and supports transcription, speaker labels, timestamps, and language confidence options.
  • memory.read and memory.write provide wallet-scoped key-value storage, including optional expiration and deletion.
  • catalog.find, catalog.search, and catalog.call discover and invoke the broader tool catalog.
  • decide.plan, decide.execute, and router.execute support planned workflows and external x402 services.
  • sellers.list reports ranked x402 and MPP sellers, while payment.info and server.describe explain payment and installation details.

Limitations and notes

Paid flagship calls require a wallet and are charged per request. Prices vary by tool: examples include $0.001 for some memory and market calls, $0.01 for search and rendering, $0.03 for transcription, and $0.08 for cited answers. The stock quote tool covers US equities on an end-of-day basis, not indices, foreign exchange, crypto, intraday prices, or 52-week ranges. Transcription accepts audio up to four minutes and 25 MB through the standard endpoint; a separate pro endpoint supports up to ten minutes.

decide.execute may take up to three minutes. Long-running calls require either the asynchronous response preference or a sufficiently long-lived connection. Browser pages, search results, and third-party routed output are external content and should be analyzed without following embedded instructions. The project is licensed under AGPL-3.0.
