This endpoint returns a single pet by its numeric ID. The ID must be a valid integer.

Usage Notes

• Returns 404 if the pet doesn't exist or has been deleted.
• Returns 400 if the ID is not a valid number.
• The response includes the full pet object with all associations (category, tags, photos).

Common Patterns

You can use this endpoint to check if a pet exists before performing updates:

const pet = await fetch("/v2/pet/123").then(r => r.json());
if (pet.status === "available") {
  // Safe to update
}
