Overview

AI-generated overview

A remote MCP server that renders public web pages in a headless browser and ranks x402 pay-per-call services, charging USDC per call.

What you can do
Render a public URL in a real headless browser and get back a PNG screenshot, a PDF, or the JavaScript-rendered HTML, useful for client-rendered pages that plain fetches return empty for. List the available categories for x402 service rankings. Get a ranked list of x402 pay-per-call services for a category, scored by price, usage volume and recency from the live Coinbase Bazaar feed.
When to use it
Use it when an assistant needs a visual or rendered version of a page that plain HTTP fetching cannot capture, or when you want to compare x402 pay-per-call services for a task category.
Requirements
A remote endpoint at x402-snap.zaden-gaming.workers.dev over streamable HTTP; no account, API key or header is declared. Rendering and ranking calls are paid at $0.02 per call in USDC on Base via the x402 protocol, so a funded wallet and payment flow are needed; the category listing is free.
Before you install
Two of the three tools cost $0.02 per call in USDC on Base, so repeated use spends real funds; the first call without x_payment returns payment details. Rendered URLs are sent to a third-party service, and the ranking data comes from the Coinbase Bazaar feed.

Installation

In SourceWeft

  1. Open x402-snap 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/io.github.ZadenGG%2Fx402-snap/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

Other MCP clients

Add this to your client's mcpServers config.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
