Overview

AI-generated overview

Live marketplace price data for eBay, Vinted, Poshmark, Reverb and Shopify, plus a cross-marketplace resale comparison, paid per call in USDC.

What you can do
  • Look up eBay market data for a keyword across 8 sites, with price range, seller concentration and optional profit from your cost
  • Search Vinted listings in 14 countries with price stats and a used-eBay resale check for five countries
  • Summarise and list products from any Shopify store, including discounts, stock and new arrivals
  • Search Poshmark and Reverb listings with market summaries by condition, brand, size or make
  • Compare one product's price across eBay UK, Vinted UK, Reverb and Poshmark, showing cheapest place to buy, best place to sell after fees, and flip profit
When to use it
Useful for resellers, sourcing and pricing research, or any assistant task that needs current second-hand and retail marketplace prices rather than guesses. Worth adding when you want listing-level data and flip-profit estimates across several marketplaces in one place.
Requirements
Remote streamable HTTP endpoint; no account or API key is needed. Each paid call is settled in USDC on Base via x402, so a wallet or x402-capable client able to pay a few cents per call is required. Network access to the endpoint is needed.
Before you install
Every tool call costs money (roughly 0.02 to 0.05 USDC per call), so automated or repeated queries spend real funds; the server states bad input is refused free and failed calls are not charged. Payments go through x402 on Base, which involves a crypto wallet. Results are third-party marketplace data and may be incomplete or change between calls.

Installation

In SourceWeft

  1. Open L50 Marketplace Data 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.lewisororke%2Fl50-marketplaces/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

83% 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.
