Palindrome Checker API

Palindrome Checker tests whether a string reads the same forwards and backwards, with options to ignore casing, spacing, and punctuation. It returns the boolean verdict, the normalized text, the reversed comparison string, and the length of the longest palindromic sequence.

The Palindrome Checker API provides a simple, reliable way to integrate palindrome checker functionality into your applications. Built for developers who need production-ready palindrome checker capabilities without the complexity of building from scratch.

Every APIVerve endpoint returns the same envelope — check status, then read data:

{
  "status": "ok",
  "error": null,
  "data": { ... }
}

A real response from the Palindrome Checker API:

{
  "status": "ok",
  "error": null,
  "data": {
    "text": "A man a plan a canal Panama",
    "is_palindrome": true,
    "cleaned_text": "amanaplanacanalpanama",
    "reversed_text": "amanaplanacanalpanama",
    "length": 21,
    "options": {
      "ignore_case": true,
      "ignore_spaces": true,
      "ignore_punctuation": true
    },
    "longest_palindrome_substring": "amanaplanacanalpanama",
