Joonggonara Scraper: Korea New Listing Alerts

Watch a search, get only what's new. This actor runs your search against Joonggonara (web.joongna.com) — Korea's largest second-hand classifieds marketplace — and returns one clean row per listing: title, price, status, location, and a permanent link. Turn on monitoring and it becomes a watchlist: new listings and price drops since your last run, charged per new row, free on quiet days.

Who it's for

A reseller or arbitrage buyer watching one category (phones, laptops, sneakers) for underpriced or newly-posted listings wants a live feed of what's actually on Joonggonara right now, without refreshing the search page by hand. A market-research team tracking asking prices, or a Sheets/n8n workflow that reacts the moment something new is posted, gets the same shape here: paste a list of search terms, get back a flat row per listing, and pay only for listings actually returned — a search that finds nothing costs nothing.

Use it alongside bunjang-listing-lookup and daangn-listing-lookup — all three Korean second-hand marketplaces in this catalogue share the same column names (listingId, title, price, currency, status, postedAt, city, sellerType, sellerHash, imageUrl, url) so their rows merge cleanly into one feed.

Why this one

• Monitoring first, not a one-off dump. Turn on "Only return results that are new, or dropped in price" and this actor becomes a watchlist: it remembers every listing ID it has already shown you, and only bills you for what's actually new or has dropped in price since the last run. A quiet run — nothing new, nothing cheaper — still finishes and costs only the base run fee.
• No competing monitoring actor. The current Apify Store leader for Joonggonara, kdatafactory's scraper, has 2 lifetime users at $4 per 1,000 items and no monitoring mode. Korea's DIY alert-bot scene (GitHub bots posting new Joonggonara listings to Discord/Telegram) is the strongest signal of unmet demand found anywhere in this catalogue's Asia research.
• Never charged for a miss, or a quiet monitoring run. A search that finds nothing, or a scheduled watchlist run where nothing changed, still gets a row explaining what happened — and costs nothing.
• Honest about the site's real page cap. Joonggonara serves 50 listings per search on this route with no confirmed way to page further (probed live, not assumed — see the FAQ). This actor returns those 50 and reports the true total (totalAvailable) separately, rather than silently under-delivering.
• Paste a keyword or your own saved search URL. Type plain keywords (including Korean, e.g. "맥북"), or paste a web.joongna.com search URL you've already run in your browser.

What you get

One row per listing by default (turn off "Expand rows" in Advanced to get one row per search instead, with the listings nested under listings).

Field	Type	Description

Deselect any field in the Input tab's column picker to drop it from every row — query, found, status, message, and scrapedAt always stay.

Pricing

Pay-per-event. A flat per-run fee covers session/proxy warmup; you're billed per item only when data is actually found and returned — see .actor/pay_per_event.json for exact prices. A miss is never charged.

Monitoring / only new results

Turn on "Only return results that are new or dropped in price since the last run" and a search line becomes a watchlist instead of a one-off dump:

• A listing counts as new the first time its Joonggonara listing ID is returned by this watchlist.
• A listing counts as a price drop when its price falls by at least "Minimum price drop to alert on" (5% by default) since it was last seen — measured against the most recently seen price. Joonggonara has no bidding system, so every listing's price is a real, comparable fixed price (unlike a marketplace with auctions, there's no price-type gate here).
• Already-seen, unchanged listings are dropped before you're billed. A quiet run — nothing new, nothing cheaper — still finishes and returns one free row.
• The first run has nothing to compare against. By default it returns everything it finds as "new". Turn on "Skip alerts on the first run" to instead have the first run bank everything quietly with zero rows and zero charge, and start alerting from the second run on — this stops a fresh watchlist from firing a wall of "new listing" messages on day one.

Schedule recipe. Save this actor as an Apify Task with deltaMode: true and a deltaName you choose, add an hourly (or daily) Schedule, and point the task's webhook at Discord, Slack, Google Sheets, or an n8n/Make webhook URL to get pinged only when something actually changes.

Coverage limitation. Because this route serves only 50 listings per search with no confirmed pagination, a very high-volume keyword (like "iphone", which had over 17,000 matching listings live) will always show truncated: true — monitoring still works (Joonggonara's own newest-first sort means the freshest listings are always in that first 50), but keep a monitored search reasonably narrow (a specific model, not a whole category) if you want to be sure nothing scrolls past the cap between runs.

How to use

1. In the Apify Console. Open the actor page and click Start — the searches field is already pre-filled with a working example. Results land in the run's dataset as soon as each item is found.
2. Via the API. Call it directly with a POST request — no Console needed once you have an API token:

   curl "https://api.apify.com/v2/acts/accountable_eel~joonggonara-listing-lookup/run-sync-get-dataset-items?token=<YOUR_TOKEN>" \
     -X POST \
     -H "Content-Type: application/json" \
     -d '{"searches":["iphone"]}'
   

3. On a schedule. Save this actor as an Apify Task with the input you want, then add a Schedule (hourly, daily, weekly) so it runs on its own — no server of your own required.

4. Turn on "Only return results that are new or dropped in price since the last run" under Monitoring once you want a watchlist instead of a one-off dump — see "Monitoring / only new results" above.

Input

{
  "searches": [
    "iphone"
  ]
}

One search per line — keywords like "iphone" or "맥북", or paste a web.joongna.com search URL. Accepted formats: iphone, 맥북, https://web.joongna.com/search/iphone?sort=RECENT_SORT.

Sample output

A search that finds nothing comes back as a row with "found": false and is never charged.

Use it from Clay, n8n, Make, or an AI agent

This actor runs synchronously over plain HTTP — call it directly from a script, a workflow tool, or an AI agent, no Apify Console needed once you have an API token.

curl "https://api.apify.com/v2/acts/accountable_eel~joonggonara-listing-lookup/run-sync-get-dataset-items?token=<YOUR_TOKEN>" \
  -X POST \
  -H "Content-Type: application/json" \
  -d '{"searches":["iphone"]}'

n8n. Add an HTTP Request node: Method POST, URL https://api.apify.com/v2/acts/accountable_eel~joonggonara-listing-lookup/run-sync-get-dataset-items?token=<YOUR_TOKEN>, Body Content Type JSON, JSON Body {"searches":["iphone"]} (swap in an expression from an earlier node for a real value).

Clay. Add an "HTTP API" column: Method POST, URL https://api.apify.com/v2/acts/accountable_eel~joonggonara-listing-lookup/run-sync-get-dataset-items?token=<YOUR_TOKEN>, Body {"searches":["{{search}}"]}, mapping the row's search into the searches array.

MCP. In Claude, Cursor, or any MCP client with the Apify MCP server, ask for "Joonggonara Scraper | Apify" — the agent will find and run this actor.

Tips

• Start monitoring with "Skip alerts on the first run" on for any watchlist you're setting up on a schedule — it avoids a wall of "new" alerts for your entire current search result on day one.
• Keep a monitored search reasonably narrow (a specific model, not a whole category) — see "Coverage limitation" above for why a huge catch-all search can miss listings that scroll past the 50-item cap between runs.
• A BLOCKED status means Joonggonara returned a 403, 429, or 503 — lowering "Max concurrency" or trying again shortly usually clears it; this actor doesn't need a proxy by default.
• Use all three Korean marketplace actors together (this one, bunjang-listing-lookup, daangn-listing-lookup) for one alert feed across Korea's whole DIY-alert-bot territory — their shared column names make merging the three outputs straightforward in Sheets or n8n.

vs. kdatafactory's scraper

The current Apify Store leader for Joonggonara, kdatafactory's actor, has 2 lifetime users at $4 per 1,000 items and no monitoring mode. This actor adds new-listing and price-drop monitoring as a first-class mode, at half the per-item price, and bills only for listings actually delivered.

	What it costs	What you get	Trade-off
This actor	$2 per 1,000 listings; nothing for a miss or a quiet monitoring run	Monitoring mode (new + price drop), anonymous seller hash, permanent listing link	Capped at 50 listings per search (the site's own page limit — no further pagination is reachable)
kdatafactory's scraper	$4 per 1,000 items	A one-off dump	No monitoring
Doing it yourself	Your time to build and maintain a scraper, a seen-listing store, and a price-tracking layer	The same data	This actor's RSC parsing and monitoring state are the maintenance burden it absorbs

Data & privacy

This actor reads public search results that anyone can see without logging in. It doesn't log in, solve CAPTCHAs, or reveal hidden contact details. Seller identity is off by default: you get a private/business flag (sellerType) and an anonymous seller hash so you can group listings by seller without names — Joonggonara's own search results carry no seller display name to expose in the first place. Turning on "Include raw seller (store) ID" makes you responsible for having a lawful reason to process that personal data. Not affiliated with Joonggonara / 중고나라.

Is this allowed? It collects the same public listing data your browser shows, for the searches you choose. It's built for monitoring a search, not for copying the marketplace. South Korea's Supreme Court held in 2022 (case 2021Do1533) that scraping publicly available web data did not breach copyright or information-protection law — favourable context, not a substitute for checking that your own use fits Joonggonara's terms and your local law.

FAQ

Why is a row empty, or why does found say false? Either the input line was blank (status: BAD_FORMAT), Joonggonara returned a 403/429/503 (status: BLOCKED), or the search matched nothing right now (status: NOT_FOUND). Check the message column for the specific reason. None of these are billed.

Am I charged for a quiet monitoring run? No. When monitoring finds nothing new and no price drops, you get one row with listingCount: 0 — Actor.charge() only fires when listingCount is greater than zero.

Why is totalAvailable so much bigger than listingCount? Joonggonara serves exactly 50 listings on this search route with no confirmed way to page further (probed live: replaying the request with a second-page parameter returned the identical 50 listings back). This actor is honest about that cap — truncated: true tells you more existed. Joonggonara's own newest-first sort means the freshest listings are always inside that first 50, so monitoring still works well for reasonably specific searches.

What does listingStatus: for_sale mean, and are there other values? Joonggonara's own default search filter already excludes completed sales, so every listing this actor can return is on-sale. If that ever changes you may see a state_<n> value this actor hasn't mapped a label for yet — it's passed through rather than hidden.

Do I need to configure proxies? No. This actor uses Apify's default proxy configuration (no proxy group) out of the box — Joonggonara doesn't block plain requests from Apify's datacenter IPs.

Can an AI agent call this directly? Yes. It's registered on the Apify MCP server — an agent in Claude, Cursor, or another MCP client can find and run it by name ("Joonggonara Scraper | Apify"), or you can call the REST endpoint shown above from any script or workflow tool.
