9 runs each, 7 November 2026. How we measure
The task
Each side ran the same three searches. Each search has a keyword, a city and price limits.
| Query | Parameters |
|---|---|
| q1 | query = fahrrad, location = Berlin, min_price = 50, max_price = 300 |
| q2 | query = ikea sofa, location = Hamburg, max_price = 200 |
| q3 | query = iphone 13, location = München, min_price = 150, max_price = 400 |
Pass check: at least five listings, each with a title and a price.
Results (7 November 2026)
| Wield recipe | Browser agent | |
|---|---|---|
| Runs passing the check | 9 of 9 | 2 of 2 |
| Median time per run | 759 ms | 125.3 s (125,287 ms) |
| Model cost per run | $0 | $0.21 |
| Requests per run (median) | 2 | 351.5 (to the site: 23.5) |
| Blocked by the site | 0 runs | 0 of 2 runs |
Wield's fastest run took 550 ms and its slowest took 7.8 s. The recipe had no failed runs.
Why the results differ
The recipe makes two requests per run. It runs from a Kleinanzeigen tab in your own browser, at human pace, so it uses the session you already have. No model sits in the loop.
The browser agent loads many pages to reach the same listings. A median run took 6 steps, 351.5 requests (23.5 of them to the site), 55,837 input tokens and 2,516 output tokens. Most of its requests went to hosts other than the site.
The log records no HTTP 401, 403 or 429 errors from Kleinanzeigen in the browser-agent runs. The gap is in time and cost. With two runs, this page cannot show a pattern in how the site treats agents.
Caveats
- Very small sample for the browser agent. Two runs, so treat its numbers as a rough guide.
- Preliminary. The benchmark was still running on 7 November 2026.
- Paced. Runs are paced at about 30 site requests per hour, so counts are low on some sides.
- Model cost only. Wield's $0 covers model cost. It does not count your time.
Terms of Kleinanzeigen
Kleinanzeigen's terms forbid automated mass retrieval of listing data. The recipe runs one search that you start, at human pace, from your own browser. Do not loop over pages in bulk or store listings. Seller contact goes through a separate message-seller recipe, which needs your login and your explicit Allow.
