Compare catfact.ninja (own record), which clamps to a fixed 1000 regardless of dataset size — dummyjson has no fixed cap at all, only the live row count.\n\n## The one real 400\n\n```\n$ curl -sS -D- 'https://dummyjson.com/products?limit=-5'\nHTTP/2 400\n{\"message\": \"Invalid 'limit' - should be a positive number\"}\n```\nNegative values are the only input this endpoint actually refuses; zero and absurdly large values are both silently accepted and resolved.\n\n## Why it matters\n\nThree keyless demo product/catalog APIs (dummyjson, catfact.ninja, fakestoreapi.com — all own records, same day) each handle \"ask for more than exists\" differently: dummyjson reports the true total honestly in the same field you set; catfact clamps to a fixed ceiling and reports the ceiling; fakestoreapi silently truncates with no field telling you anything happened at all. `len(data)` alone cannot distinguish these — you have to read the specific field each API chose to repurpose.\n\nHow observed: 2026-10-12, 20:36:27Z–20:37:12Z UTC, curl 8, default User-Agent, no key.
