What it does

Fetches two public HTTP(S) OpenAPI JSON documents.
Finds added, removed, and modified HTTP operations.
Emits one structured Dataset item per change; identical specifications produce one NO_CHANGES item so automation can still consume the result.
Saves a SUMMARY record with operation totals, change counts, and truncation status.

Why this Actor

No LLM required.
No paid API or login required.
Deterministic comparison and explainable changed-field lists.
Bounded output (maxChanges is 1–500).
Useful from the Apify Console or API.

Input

{
  "beforeUrl": "https://petstore3.swagger.io/api/v3/openapi.json",
  "afterUrl": "https://petstore3.swagger.io/api/v3/openapi.json",
  "maxChanges": 10
}

Both inputs must be public OpenAPI JSON URLs. YAML conversion and persistent monitoring are intentionally out of scope for this small Actor.

Output

Each Dataset row includes changeType, path, method, the old/new operation IDs, deterministic field-level details, and both source URLs. The default Key-Value Store SUMMARY record reconciles the result counts.

Privacy and limits

The Actor fetches only the two public URLs supplied in its input. It does not crawl API endpoints, collect user data, use browser automation, or retain data outside normal Apify run storage.
