API.SH vs the official Marktplaats API

Marktplaats has an official API (api.marktplaats.nl) with OAuth 2.0, built for sellers and partners to place and manage their own ads, bids and statistics; business accounts usually connect through certified feed partners. API.SH needs no OAuth app or Marktplaats account and returns public ads and business sellers as JSON.

Instead of maintaining a Python Marktplaats scraper or paying per run for Apify actors, API.SH gives you search, ad and seller data with one key and a fixed price per call.

Marktplaats API questions

What Marktplaats data can I get?+

Ad search with category, postcode, distance, price and attribute filters (/marktplaats/v1/search), one ad with description, attributes, shipping, views, favourites and bids (/marktplaats/v1/listing), and a business seller with rating and active ads (/marktplaats/v1/seller).

How much does the Marktplaats API cost?+

Every Marktplaats endpoint costs 1 credit per call. On a monthly plan 1,000 credits cost $1 (Starter is $50/month for 50,000 credits). Pay-as-you-go is $2 per 1,000 credits, with top-ups from $15 that never expire.

Is there a free trial?+

Yes. Every account gets 1,000 free credits every month. That is 1,000 calls to /marktplaats/v1/listing at 1 credit each.

Is there an official Marktplaats API?+

Yes. The Marktplaats API uses OAuth 2.0 and is meant for managing your own ads, bids and statistics, often through certified partners. API.SH is for reading public ads without that setup.

Do I need a Marktplaats account or API key?+

No Marktplaats account or OAuth token is needed, only your API.SH key. API.SH reads public ads only, and private sellers' names, phone numbers and email addresses are never returned.

Can I use the Marktplaats API from Python?+

Yes. Call it with requests or the API.SH Python SDK; every response is JSON.

Can I monitor Marktplaats for new listings?+

Yes. Search with your keyword, postcode and distance, sort by date and use offered_since, then run it on a schedule with Zapier, Make, n8n or your own code.

How do I get started?+

1. Sign up at api.sh. 2. Copy your API key. 3. Call /marktplaats/v1/search with q and a postcode. Every parameter and request example is in the docs at https://api.sh/docs. You can also use the JS or Python SDK, Google Sheets, Zapier, Make, n8n or the MCP server at https://api.sh/mcp.
