Mercari Scraper: US Listings, Prices & Resale Data

Scrape Mercari US listings and prices in one run. Built for resellers, price comparison, and market research: fast, reliable, and returned as clean structured JSON. Runs with defaults and works as an MCP tool for AI agents.

What it does

Give it a search term (or leave it empty for the newest listings) and it scrapes Mercari's US marketplace. Every listing comes back as a structured record you can build on:

• US resale price data at scale on one of the largest US consumer second-hand markets
• Search by keyword or pull the newest listings
• Discount signal: surfaces the real was-price on marked-down items (~46% of listings carry a discount)
• Reliable through Mercari's Cloudflare anti-bot protection
• Stable JSON schema: safe to depend on in code and pipelines
• Runs with defaults and MCP-ready: AI agents can discover and call it as a tool

Input

Field	Type	Default	Description
query	string	""	Search term. Empty = newest listings.
countries	array	["us"]	Marketplace region. Mercari runs on US / USD.
maxItems	integer	100	Max listings returned.
filters	object	{}	Optional filters: category, brand, condition, price_min, price_max.
proxyConfiguration	object	required	US residential proxy. Mercari is Cloudflare-gated, so a US residential proxy is required.

Example input

{
  "query": "nike",
  "maxItems": 100,
  "filters": {}
}

Output

Each item is one dataset record:

{
  "id": "m12345678901",
  "url": "https://www.mercari.com/us/item/m12345678901/",
  "title": "Nike hoodie",
  "price": { "amount": 20.9, "currency": "USD" },
  "originalPrice": { "amount": 35.0, "currency": "USD" },
  "brand": "Nike",
  "size": "M",
  "condition": "Good",
  "category": "Athletic",
  "country": "us",
  "images": ["https://static.mercdn.net/item/detail/orig/photos/....jpg"],
  "listedAt": "2026-06-22T00:00:00+00:00",
  "isPromoted": true,
  "status": "on_sale",
  "scrapedAt": "2026-07-10T12:00:00+00:00"
}

Optional fields (like originalPrice) appear only when present on the listing.

• originalPrice appears only on marked-down items: a real was-price. Roughly 46% of listings carry a discount.
• status is availability: on_sale or trading.
• isPromoted flags seller-boosted listings.
• listedAt is derived from the primary photo timestamp, so it is an approximate list time.

Use cases

• Reseller sourcing: find underpriced and discounted listings to flip
• Price monitoring: track prices for brands, categories, or conditions over time
• Market research: supply, pricing, and brand trends on a major US resale marketplace
• AI agents: a reliable data tool an agent can call to answer "what does X sell for on Mercari?"

Pricing

Pay per result: you are charged per listing returned, so you only pay for data you actually get. See the exact per-event price on this Actor's page.
