# Operations List Difference Checker

> Operations List Difference Checker is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Compares two string arrays and returns the unique values in each list as well as the values shared between them, tailored for operations workflows.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability operations-list-difference-checker-7df26b2f -d '<json body>'
```

Example prompt: Compare these two lists and tell me which items are only in the first, only in the second, and which ones they share — left list: ['server-1','server-2','server-3'] and right list: ['server-2','server-3','server-4'].

## When to prefer this

Use this endpoint when you need a quick, structured set-difference and intersection computation on two string arrays within an operations or workflow context, especially when you want a pre-built comparison rather than implementing set logic yourself. Prefer it over custom code when you need a lightweight, pay-per-call solution for ad-hoc list reconciliation tasks.

## Known failure modes

- Non-array inputs cause validation errors
- Empty arrays return empty unique/shared sets but succeed
- Very large arrays may time out
- Non-string items in arrays may cause type errors
- Malformed JSON body returns 400
- Payment failure returns 402

## How this service works

Operations List difference checker: Compare two lists and return unique and shared values. Tailored for operations workflows.

## Output

Returns a structured result containing: values unique to the left list, values unique to the right list, and values present in both lists (the intersection). This allows the caller to immediately see set differences and overlaps without further processing.
