x402-paid tools: render pages, host files, delayed callbacks, pump.fun launch feed, trend radar
Pay-per-call remote MCP server that renders web pages, hosts files, schedules delayed callbacks, and returns pump.fun launch and trending-topic feeds, paid in…
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
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.huntercarver24%2Fsignal-desk/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.Add this to your client's mcpServers config.

}Pay-per-call tools for AI agents, paid in USDC on Base through x402. No account and no API key: the first call answers 402 Payment Required with the price, the agent's wallet signs a transfer for exactly that amount, and the second call gets the result plus a receipt. Settlement happens only after the work succeeded, so a call the service refuses is never charged.
Every route's fields, limits and an example are in its 402 answer and in GET / on the HTTP host. Every refusal (bad input, private address, executable upload) carries the same usage object, free.
Use a throwaway wallet holding a few cents of USDC on Base, never a main wallet.
npm install @x402/core @x402/evm @x402/fetch viem, Node 20 or later, saved as an .mjs file.
The x402-pay skill teaches Claude the five routes and pays them with scripts/pay.mjs. Claude says the price before the first paid call, and each payment runs as a command you approve.
An MCP client needs x402 support to pay; any other client still lists the tools and sees each price in a payment-required result. With @x402/mcp:
npm install @modelcontextprotocol/sdk @x402/core @x402/evm @x402/mcp viem.
Then add the dependencies listed in opencode/package.json to .opencode/package.json; OpenCode installs them at startup. The agent gets the five tools.
retry-after instead of charging for stale data.monitor/check.mjs probes every surface a paying agent touches, for free, every 15 minutes: the paywall's health and configuration, a live 402 with its terms, the trend sources' freshness, the launch feed's lag, and both MCP endpoints. The badge above is its latest result.
Known issue: the launch feed's Solana data provider has blocked the project since October 29, 2026. Until that clears, POST /launches and recent_launches refuse with a free 503; the other four tools are unaffected.
MIT. The services themselves are run by Hunter Carver; this repository holds the clients, the uptime check and these docs.

Render a web page
Renders a public web page in a real headless browser (JavaScript runs, redirects are followed) and returns it as clean markdown, a PNG screenshot or a PDF. One call, one payment, no account. A render that fails is not charged. Price: $0.01 per call in USDC (x402).
urlrequiredwidthformatheightfullPageselectorpdfFormattimeoutMswaitUntilwaitForSelectorHost a file
Hosts a file: upload up to 10 MB as base64 with its content type and get back a public download URL that serves the bytes with that content type for 1 to 168 hours (default 24). Downloads are free, readable at once where uploaded and everywhere within about a minute. Executables are refused; HTML and SVG are served as attachments. A failed upload is not charged. Price: $0.01 per call in USDC (x402).
datarequiredfilenamettlHourscontentTyperequiredSchedule a callback
Schedules a delayed HTTP callback: give a public URL, an optional JSON body, optional headers and a delay of 60 seconds to 7 days (or an absolute time), and the URL is called at that time (POST when a body was given, otherwise GET), with one retry and a 10-second timeout. The answer carries a free status URL that reports whether it fired and what the callee answered. A request that is refused is not charged. Price: $0.005 per call in USDC (x402).
aturlrequiredbodyheadersdelaySecondsRecent pump.fun launches, trend-matched
Lists pump.fun token launches from the last N minutes (decoded from Solana mainnet within about a minute), each with its creator wallet, that wallet's seven-day launch count, and, when the coin's name matches a topic currently trending on Google Trends or moving on Polymarket, the matched trend with its source and score. Launch data only; it does not rate, recommend or trade anything. Price: $0.005 per call in USDC (x402).
limitcreatorminutestrendOnlyTrending topics, cross-source
Lists topics trending right now across Google Trends (US realtime) and Polymarket (markets moving on volume), merged by topic, strongest first, each with score, score velocity per hour, first and last seen times, a type label (person, brand, event, place, meme, other), the headlines or market numbers behind it, and how many pump.fun launches in the last hour match it. Sources are polled every five minutes. Price: $0.01 per call in USDC (x402).
hourslimitsourceminScore100% of the applicable checks met
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.
