Marktplaats searches to watch for price drops

searches

Required

One search per line: keywords like "iphone", or paste a marktplaats.nl search URL (its filter fragment after # is not read; use the Postcode / Distance / Price type fields below instead). Each line becomes a watchlist: the first run remembers the prices it finds, and every run after it returns only the listings that got cheaper. Accepted formats: iphone, racefiets, https://www.marktplaats.nl/q/iphone/. You're only charged for the ones we actually find — a miss costs nothing.

Type:array

Try it first — only process the first 5

testRun

Optional

Turn this on to test your input on a small sample before running the full list. Turn it off to process everything.

Type:boolean

Default:false

Hide rows with no result

onlyFound

Optional

Only keep rows where something was actually found. Misses are always free, whether or not you show them here.

Type:boolean

Default:false

Title must contain (optional)

includeKeywords

Optional

Optional. One keyword per line, case-insensitive. A listing is kept only if its title contains at least one of these. Leave empty to keep every title.

Type:array

Title must not contain (optional)

excludeKeywords

Optional

Optional. One keyword per line, case-insensitive. A listing whose title contains any of these is dropped. Leave empty to drop nothing.

Type:array

Stop after this many results

maxResults

Optional

Optional. Stop the run once this many results have been found — useful for a quick, cheap sample. Leave blank for no limit.

Type:integer | null

Minimum:1

Most listings to check per search

maxListingsPerSearch

Optional

Marktplaats returns up to 100 listings per request (the real, confirmed ceiling: 101 is rejected); this actor pages automatically above that, up to 1000 per search. This is how deep the watchlist looks, not how many rows you get back: you only pay for the listings whose price actually fell.

Type:integer

Default:100

Minimum price (EUR)

minPrice

Optional

Optional. Drop listings priced below this. Leave empty for no minimum. Applied after fetching (no confirmed API price-range parameter).

Type:integer

Maximum price (EUR)

maxPrice

Optional

Optional. Drop listings priced above this. Leave empty for no maximum. Applied after fetching (no confirmed API price-range parameter).

Type:integer

Conditions to keep (optional)

conditions

Optional

Optional. One per line: new_with_tags, new, like_new, good, fair, unknown. Leave empty to keep every condition. Matched against Marktplaats' own Dutch labels (Nieuw, Zo goed als nieuw, Gebruikt, Niet werkend, Refurbished — there is no "with tags" grade, so new_with_tags never matches). A listing with no condition attribute is unknown.

Type:array

Cities to keep (optional)

cities

Optional

Optional. One city name per line, case-insensitive, matched as a "contains" against the listing's own city. Leave empty to keep every location.

Type:array

Sort by (optional)

sortBy

Optional

Optional. Sorts the price drops this run found, after filtering. Leave empty to keep Marktplaats' own newest-first ordering (the existing default behaviour, unchanged).

Type:string

Default:

Options:

newestprice_ascprice_desc

Price type

priceType

Optional

Optional. Keep only listings of this price type. Price-drop detection only ever fires on a fixed price or an asking price, so setting this to "Fixed price" is the cleanest way to run this watchlist. FIXED, MIN_BID, FAST_BID and SEE_DESCRIPTION were observed live; BID, FREE, ASKING, TRADE and RESERVED are Marktplaats' other documented values. Applied after fetching.

Type:string

Default:

Options:

FIXEDBIDMIN_BIDFAST_BIDFREEASKINGTRADERESERVEDSEE_DESCRIPTION

Postcode to search near

postcode

Optional

Optional. A Dutch postcode (e.g. "1011AB") — confirmed live to change every listing's distance and re-center results. Leave empty to search all of the Netherlands.

Type:string

Default:

Distance from postcode (km)

distanceKm

Optional

Only used when "Postcode to search near" is set. Marktplaats' own UI offers 3, 5, 10, 15, 25, 50, 100 km — any positive number works on the API.

Type:integer

Only return listings that got cheaper since the last run

deltaMode

Optional

On by default: this is what the actor is for. The first run remembers every listing and price it finds and returns a single summary row. From the second run on, a listing comes back only when its price has fallen by at least the percentage below since it was last seen, with the old price, the new price and the drop percentage on the row. Unchanged listings are dropped before you are billed, so a quiet run costs only the start fee. Turn this off to get every matching listing instead, like an ordinary search.

Type:boolean

Default:true

Watchlist name (optional)

deltaName

Optional

Leave empty and we derive one from this run's filters, so two schedules with different filters keep separate memories. Type your own name to keep one memory across a filter change, or to have two schedules share one.

Type:string

Default:

Smallest price drop worth an alert (%)

minPriceDropPct

Optional

Only fires for a fixed-price or asking-price listing where both the old and the new price are set (never for bids, free, or "see description" listings). Default 5%: a 200 euro item has to fall by at least 10 euro.

Type:integer

Default:5

Alert on price drops

alertOnPriceDrop

Optional

On by default, and the whole point of this actor. Turning it off with the checkbox above on leaves nothing to return.

Type:boolean

Default:true

Also return listings that are brand new

alertOnNew

Optional

Off by default, so your results stay price drops only. Turn it on to also get listings this watchlist has never seen, each marked new rather than price-drop. They are billed like any other row.

Type:boolean

Default:false

Seed silently (no rows on the first run)

skipFirstRun

Optional

The first run of a watchlist has no earlier price to compare with, so it returns one summary row and no listings either way. This matters only if you also turned on "Also return listings that are brand new": with it on, the first run banks everything silently instead of returning a hundred rows at once.

Type:boolean

Default:false

Which columns do you want?

columns

Optional

Choose which pieces of information to include in each result row. All are included by default.

Type:string[]

Default:

[
  "searchQuery",
  "listingCount",
  "priceDropCount",
  "medianPrice",
  "listings",
  "listingId",
  "url",
  "title",
  "price",
  "currency",
  "previousPrice",
  "priceDropPct",
  "priceType",
  "city",
  "countryName",
  "postedAt",
  "postedText",
  "imageUrl",
  "imageCount",
  "condition",
  "conditionRaw",
  "conditionBucket",
  "category",
  "sellerHash",
  "sellerVerified",
  "sellerType",
  "isPromoted",
  "changeType",
  "firstSeenAt",
  "lastSeenAt",
  "daysListed"
]

One row per listing (recommended) — turn off for one row per search instead

expandRows

Optional

When on, each listing found gets its own row instead of being grouped under its search. You're still only charged once per search, no matter how many rows it produces.

Type:boolean

Default:true

Max concurrency

maxConcurrency

Optional

Parallel requests. Keep conservative — this target has no browser fallback, so getting blocked costs more than slow-and-steady.

Type:integer

Minimum:1

Maximum:20

Default:5

Proxy configuration

proxyConfiguration

Optional

Apify Proxy config. Residential recommended for anti-bot-sensitive targets.

Type:object

Default:

{
  "useApifyProxy": true
}
