# Mercari Scraper - Listings, Prices & Sellers (`jongoose/mercari-scraper`) Actor

Scrape Mercari US search results into structured data: item id, title, price, brand, size, condition, category, seller id, status, photo and item URL. Search by keyword or paste Mercari URLs. Reads Mercari's own GraphQL API - no HTML scraping.

## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Mercari Scraper - Listings, Prices & Sellers

Scrape **product listings from [Mercari US](https://www.mercari.com)** into clean, structured data - no Mercari account or API key required. Search by keyword or paste Mercari search URLs and get item id, title, price, brand, size, condition, category, seller id, status, photo and the canonical item URL.

### What you get (per item)

- **itemId** and canonical **mercari.com/us/item/{id}/** URL
- **title**, **price** (USD) + raw `priceCents`, `originalPrice`
- **brand** (+ brandId), **size**, **itemCondition** (New / Like new / Good / Fair / Poor) + `conditionId`
- **category** (+ `categoryId`), `topCategory` and a readable `categoryPath` (e.g. `Electronics > Video games & consoles > Consoles`)
- **status** (`on_sale`, `trading`, `sold_out`) and an `isSold` flag
- **sellerId**
- **photoUrl** (primary photo) + `thumbnailUrl`
- `promoted` flag, `countrySource`, `currency`

> **Not included on search results (by design):** the seller's *display name* and the item's *like count* are not part of Mercari's search response - fetching them would require a separate request per item, which this Actor skips for speed and cost. Both fields are present in the output schema (`sellerName`, `numLikes`) but `null` on search runs. `size` is naturally empty for items that have no size (games, electronics) and populated for fashion (e.g. `M (8-10)`).

### Input

- **Mercari URLs** *(optional)* - paste one or more search URLs (e.g. `https://www.mercari.com/search/?keyword=nintendo%20switch`). A keyword is derived from each URL's `?keyword=` param or last path segment.
- **Search keyword** *(optional)* - e.g. `nintendo switch`, `lululemon leggings`, `pokemon cards`. Used when no URL is given.
- **Sort order** - Best match, Newest, Price low→high, Price high→low, Most liked.
- **Max items** - caps the run.
- **Proxy** - **residential recommended** (see below).

#### Example input

```json
{
  "query": "nintendo switch",
  "sort": "newest",
  "maxItems": 300,
  "proxyConfiguration": { "useApifyProxy": true, "apifyProxyGroups": ["RESIDENTIAL"] }
}
```

Or paste URLs directly:

```json
{
  "startUrls": [{ "url": "https://www.mercari.com/search/?keyword=lululemon%20leggings" }],
  "maxItems": 100
}
```

### Why this actor

- **Reads Mercari's own GraphQL API** (`/v1/api` `searchFacetQuery`), not fragile CSS selectors - every field comes straight from structured JSON, so records are complete and the parser survives site redesigns.
- **No account, no login:** an anonymous guest token is minted automatically per run (`/v1/initialize`).
- **Fast + cheap:** items are read in bulk pages (100 per request) with **no per-item detail requests**; de-duplicated by item id, prices normalized to dollars, UTF-8 cleaned.
- **Clean paginating output:** offset pagination with automatic de-duplication of Mercari's repeated promoted items; stops on the last page or once `maxItems` is reached. Export as JSON, CSV, or Excel, or pull via the Apify API.

Great for resellers and flippers doing **price research, sold-comps and inventory monitoring**, and for lead/catalog building.

### Proxy - residential recommended

Mercari sits behind Cloudflare and runs its own bot scoring, so this Actor **defaults to an Apify RESIDENTIAL proxy**. Datacenter IPs may work for light use but get soft-blocked at volume. If a run comes back empty/blocked, confirm the proxy is set to residential and re-run to draw fresh IPs.

### Legal

Public marketplace data for **research**. This is **not a consumer report** and **must not be used for FCRA purposes** (e.g. eligibility for credit, employment, insurance, or housing). Respect Mercari's Terms of Service and applicable law.

# Actor input Schema

## `startUrls` (type: `array`):

Optional. Paste one or more Mercari search URLs (e.g. https://www.mercari.com/search/?keyword=nintendo%20switch). A keyword is derived from each URL's ?keyword= parameter or its last path segment. Leave empty to use the Search keyword below.

## `query` (type: `string`):

Keyword to search Mercari for, e.g. "nintendo switch", "lululemon leggings", "pokemon cards". Used when no Start URL is provided. Leave everything empty to browse the feed.

## `sort` (type: `string`):

How Mercari should sort the results.

## `maxItems` (type: `integer`):

Stop after collecting this many items.

## `proxyConfiguration` (type: `object`):

Mercari sits behind Cloudflare and its own bot scoring, so a RESIDENTIAL proxy is recommended - datacenter IPs get soft-blocked at volume. Defaults to US residential (Mercari US is a US-only site); leave it as residential for reliable results.

## Actor input object example

```json
{
  "startUrls": [],
  "query": "nintendo switch",
  "sort": "best_match",
  "maxItems": 100,
  "proxyConfiguration": {
    "useApifyProxy": true,
    "apifyProxyGroups": [
      "RESIDENTIAL"
    ],
    "apifyProxyCountry": "US"
  }
}
```

# API

// Run the Actor and wait for it to finish
const run = await client.actor("jongoose/mercari-scraper").call(input);

// Fetch and print Actor results from the run's dataset (if any)

## CLI example

```bash
echo '{
  "startUrls": [],
  "query": "nintendo switch"
}' |
apify call jongoose/mercari-scraper --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",

        }
    }
}
```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
