Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to extract.paypercall.dev, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Remote pay-per-call web intel API: page extraction, link checks, domain and IP lookups, web search, YouTube transcripts and arXiv metadata, paid in Nano.

What you can do: Extract clean text or markdown from web pages, PDFs and YouTube transcripts
Pull structured fields with CSS selectors and list every anchor link on a page
Check link status, redirect chains, TLS expiry and content drift
Look up domain intelligence (DNS, WHOIS, SSL, headers) and IP geolocation
Run web search and search AI job postings or arXiv paper metadata
Query Nano account details such as balance, representative and pending blocks
When to use it: Useful when an assistant needs on-demand web extraction, link auditing, domain or IP reconnaissance, or quick search results without signing up for an API key, and you are willing to pay small per-request fees in Nano.
Requirements: A remote streamable HTTP endpoint; no account or API key. Each call first returns an HTTP 402 challenge, so a Nano (XNO) wallet is needed to send the stated amount and retry with the returned block hash in the X-PAYMENT header. Network access to the service is required.

Before you install

Every request costs XNO, so automated or repeated calls spend real money; set limits before letting an assistant call it freely. Payment is settled by sending crypto to the address in the challenge, and the X-PAYMENT block hash acts as the credential. Requested URLs, domains, IPs and queries are sent to a third-party service.

Installation

In SourceWeft

Open Vend Api Merchant in the dashboard and add it to a workspace.
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/dev.paypercall.extract%2Fvend-api-merchant/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

Quick buyer guide

BUYERS_GUIDE.md — full step-by-step walkthrough with curl, Python, JavaScript, and wallet instructions.
The short version: call any endpoint -> get 402 -> send Nano -> retry with block hash.

How it works (buyer flow)

1. GET /api/v1/extract?url=https://example.com   → HTTP 402 with x402 payment challenge
2. Send 0.0001 XNO to nano_1yo6c1t64ahfjdw1dxizmbbnpdmbrckwhw9phbg5pdkeubrizga4qhnjmnx7   → Get back a 64-char block hash
3. GET /api/v1/extract?url=https://example.com  -H "X-PAYMENT: <block-hash>"   → HTTP 200 with the extracted text
