How this service works
Survey List difference checker: Compare two lists and return unique and shared values. Tailored for survey workflows.
Output
Returns two categorized sets: values unique to the left list, values unique to the right list, and values shared by both lists, allowing the caller to understand overlap and divergence between the two input arrays.
Example use cases
Comparing pre and post survey answers
“I ran the same survey before and after our training session. Left list is pre-training responses: ['satisfied','neutral','dissatisfied'] and right list is post-training responses: ['very satisfied','satisfied','neutral']. Can you compare them and tell me which responses are new, which dropped off, and which stayed the same?”
Finding overlapping employee feedback tags
“I have two sets of feedback tags from two different departments. Can you compare them? Department A tags: ['communication','workload','flexibility','management'] and Department B tags: ['workload','culture','management','salary']. I want to know which concerns are shared and which are unique to each department.”
Deduplicating survey option sets
“I need to merge two lists of survey answer choices but first want to know what's already in common versus what's unique to each. List one is ['never','rarely','sometimes','often'] and list two is ['sometimes','often','always']. What do they share and what's different?”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/compare-lists-survey?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, survey-context-aware list comparison that returns both unique and shared values in a single call. Prefer it over general-purpose set-difference tools when your workflow involves survey response options, answer choices, or categorical string data and you need the output formatted for survey analysis pipelines.
Side effects
- Non-array inputs cause validation errors
- Empty arrays on one or both sides return no shared values and all items as unique
- Very large arrays may time out or exceed payload limits
- Non-string array items may cause type errors depending on server-side handling
