Let your AI agent search second-hand marketplaces
Wield gives your AI agent search recipes for four second-hand marketplaces: Kleinanzeigen, eBay and Vinted in Germany, and willhaben in Austria. Each search returns listings with prices and filters, run from your own browser. Messaging a seller is a write. Wield shows you the exact message and waits for your Allow before it sends anything.

Some details from the live checks. Kleinanzeigen returns each listing's posting date in ISO format. The eBay recipe covers auctions and Buy It Now listings, with shipping and seller rating, and it marks promoted listings from their accessible label. Vinted's old JSON API returns 404, so the recipe reads the 96 item cards that its search page renders. The willhaben recipe sorted cheapest first for a bike search in Vienna, up to 300 euros.
Benchmark
Benchmark figures are preliminary, as of 7 November 2026, and the run is still going. On Kleinanzeigen, Vinted and willhaben, the browser agent also got results, in about two to three minutes per run. The Wield recipe took under a second.

What it can't do yet
- Messaging is untested.
message-sellershows the listing title and the exact message before it sends. Logged out, it stops with a login error before it sends anything. The send step needs a logged-in test first. - Your conversations are untested.
my-messagesneeds a login, and its path and fields are not verified. - No buying or bidding. These recipes search and read. The eBay recipe does no bidding and no buying.
- eBay runs only in the browser. eBay answers servers with 403, so the recipe runs only through your browser.
- Not in the benchmark yet. eBay has no benchmark data, so we have no speed or success comparison for it.
Terms of the sites
Kleinanzeigen's terms forbid automated mass retrieval of listing data. Vinted's terms prohibit scraping and automated collection. eBay's user agreement restricts automated access without permission. willhaben's terms prohibit automated reading of ads. Each recipe runs one search page at a time from your browser, at a human pace. Do not loop over pages, and do not store listings in bulk.

FAQ
Can my agent buy the item?
No. These recipes search and read. Buying and bidding stay on the marketplace site.
Can my agent message the seller?
Only on Kleinanzeigen, and that recipe is untested. Wield shows the listing title and your exact message before any send, and each run needs its own Allow. Wield also sends one message per request, because Kleinanzeigen bans bulk or templated outreach as spam.
Why does Vinted read the page instead of an API?
Its old JSON API returns 404. The recipe reads the item cards that the search page renders, which gave 96 items in our live check.
How fast are these searches?
Median times in the benchmark run from 0.58 s to 0.92 s per search. The browser agent took 125 s to 162 s at the median on the same sites.
