Mercari + Poshmark + Depop Scraper

Tri-platform fashion-resale scraper. Pull listings, sellers, brand pages, categories, and individual items from Mercari (US), Poshmark, and Depop with a single actor — no login required.

Use it to track competitor pricing, monitor a brand's secondhand availability, audit a seller's catalog, or build a multi-marketplace dataset of secondhand fashion in one place.

What you can scrape

Platform	Search by query	By item URL	By seller / closet	By brand	By category	Auto-detect URL
Depop	yes	yes	yes	yes	—	yes
Poshmark	yes	yes	yes	yes	yes	yes
Mercari	yes	yes	yes	—	yes	yes

Every mode pushes flat, omit-empty records to the dataset — no nested null/empty fields.

Modes — quick reference

searchListings

Search by free-text query. All three platforms support this.

{
  "platform": "depop",
  "mode": "searchListings",
  "query": "vintage levis",
  "sortBy": "relevance",
  "maxItems": 50
}

Filters available:

• All — query, minPrice, maxPrice, sortBy, maxItems
• Poshmark — department, nwtOnly, availableOnly
• Mercari — categoryId, itemStatus
• Depop — category, discountedOnly

byItem

Fetch a fixed list of items by URL or ID. The most reliable mode — no listing page parsing.

{
  "platform": "mercari",
  "mode": "byItem",
  "urls": ["https://www.mercari.com/us/item/m86443601198/"],
  "maxItems": 50
}

Mercari accepts either urls or itemIds (e.g. m86443601198).

bySeller

Fetch a seller's profile + their listings.

{
  "platform": "poshmark",
  "mode": "bySeller",
  "usernames": ["dr_dolittle"],
  "includeSellerProfile": true,
  "maxItems": 50
}

Mercari uses numeric seller IDs — pass them in sellerIds instead of usernames.

byBrand (Poshmark, Depop)

Listings under a specific brand.

{
  "platform": "poshmark",
  "mode": "byBrand",
  "brands": ["Nike", "Levi's"],
  "maxItems": 50
}

byCategory (Mercari, Poshmark)

Listings in a top-level category.

{
  "platform": "poshmark",
  "mode": "byCategory",
  "category": "Women-Shoes",
  "maxItems": 50
}

For Mercari, pass categoryId (e.g. 1 for Women, 2 for Men).

byUrl (auto-detect)

Drop in any URL — listing page, closet/profile, brand page, category page — and the actor figures out what to fetch.

{
  "platform": "depop",
  "mode": "byUrl",
  "urls": ["https://www.depop.com/products/awesome-vintage-jacket-12345/"],
  "maxItems": 50
}

Anti-bot strategy

Platform	Default tier	Auto-escalate
Depop	Apify residential proxy (Depop's Cloudflare hard-blocks datacenter IPs on the public web API)	No further escalation needed
Poshmark	curl_cffi Chrome-131 (no proxy)	On 403/429: datacenter → residential
Mercari	curl_cffi for byItem / byUrl-of-item; headless Chromium routed through Apify residential for searchListings / byCategory / bySeller listings	Yes

You can disable auto-escalation by setting autoEscalateOnBlock: false (the run will fail fast on first block). Pass custom proxy groups via proxyGroups.

FAQ

Why does Mercari searchListings use a browser? Mercari's search results are 100% client-rendered. The XHR is a Bearer-JWT-signed Apollo persisted query, and the JWT issuer (/v1/initialize) is gated by Cloudflare — so we drive a real Chromium that Mercari's React app can sign requests through. Item-detail pages are server-rendered, so byItem is HTTP-only and fast.

Why is Depop on residential proxy by default? Depop's webapi.depop.com returns HTTP 403 to every datacenter IP we've tested (curl_cffi chrome131/120/116/safari17, all the same). Apify's residential proxy bypasses this reliably.

Daily test runs? The actor's prefill is set to platform=depop, mode=searchListings, query="vintage levis", maxItems=10 — Depop reliably returns ≥10 records on residential proxy.

Do I need to provide cookies? No. None of the three platforms require login for the modes shipped here.

What's the max items per run? 1000 (maxItems upper bound). Each platform paginates differently — Depop and Poshmark return up to ~48 per page, Mercari ~20 per page.

What currencies are returned? Mercari is always USD. Poshmark is USD by default. Depop returns the seller's local currency (USD/GBP/EUR/AUD/etc.) via the currency field.

Image URLs — are they accessible? Yes. CDN images from mercdn.net (Mercari), di2ponv0v5otw.cloudfront.net (Poshmark), and Depop's CDN are all hotlinkable. No KV-rehosting required.

Tips

• Search-listing mode is paginated. Mercari's browser-driven path scrolls to load more items; Depop paginates via offset_id; Poshmark returns 48 in __INITIAL_STATE__.
• byItem is the fastest and most stable mode — use it whenever you already have a list of item URLs/IDs.
• byUrl is the most ergonomic — drop in 10 mixed URLs (some listings, some closets, some brand pages) and the actor dispatches each correctly.
• Boundary checks: minPrice/maxPrice filters apply to price after parsing; if currency differs across listings (Depop with global sellers), the comparison is done in the listing's native units.

Limitations

• Mercari API is gated — the official internal /v1/api requires a Bearer JWT issued from /v1/initialize, which we can only obtain by driving a real browser. We've documented the headers if you want to extend this actor with a captured-token mode in the future.
• Poshmark seller profile bio + recent reviews require additional XHR calls we don't currently make — only the basic profile fields are emitted.
• Depop product pages from datacenter IP are 403 — even with the SSR HTML fallback, you'll need residential proxy. The actor handles this for you.
