How Knit builds this workflow
The Agent researches both APIs and wires the trigger on one side to the action on the other — no pre-built connector required. Here is the vocabulary it has to work with.

Common questions
Can Knit build “Classify website changes” between ZenRows and Langfuse?
Yes — describe it in the box above and Knit's Integrations Agent researches ZenRows and Langfuse's public API docs (or your own uploaded docs) and builds a working workflow, whether or not either app already has a pre-built connector.
How long does it take to build?
Minutes to a first working version, not weeks — you test it against real data before it goes anywhere near production.
Why send scraped pages to an AI model?
Scraped HTML and text are noisy. Passing each ZenRows result to Langfuse lets you pull out prices, names or key points in a consistent shape instead of cleaning the data by hand.
Can the model decide which pages to scrape next?
Yes. You can have Langfuse produce a list of URLs or search terms, then run a scrape in ZenRows for each one.
