Batch URL Fetcher

Demonstrate the Loop → HTTP → Merge pattern: provide a JSON array of URLs and get back an aggregated array of responses — all without writing a line of code.

What this workflow does

Input holds a JSON array of target URLs
Loop iterates over each item in the array one by one
HTTP fetches each URL individually
Merge collects all responses into one output array
Output exposes the aggregated results

Use cases

Batch-check multiple API endpoints in one run
Multi-source data ingestion pipelines
Parallel enrichment without custom code

Notes

Large batches may hit rate limits on the target API. Add a Wait node inside the loop body for rate-limiting scenarios.
