Find longest word

Finding the longest word in a passage is a sharp, everyday check for typography fit, readability reviews, and word puzzles.

Run — free How it works & API

Use it from WebAPIEmailTelegramApp soon

Paste non-empty text and this capability scans Unicode letter runs, measures each token by letter count, and reports the winning word together with its length. When several words share that maximum, every distinct winner is listed in first-seen order so ties are visible instead of hidden. Punctuation, digits, and emoji act only as separators, so a trailing comma never inflates a length and never becomes a fake champion. Empty strings and punctuation-only input fail with invalid input rather than inventing a zero-length answer. The free browser widget and the prepaid API share one deterministic function, so classroom checkers and production pipelines never disagree on the same string. Successful API calls are billed at $0.002 per item; validation failures are not charged.

How to use it

Enter your values in the form above. The tool checks them before calculating and shows the result on the same page.

Check your inputs

Use it again or automate it

Use the browser tool for individual checks and the API when you need the same capability in an automated workflow.

What you can do with it

Get an answer now

Enter one set of values and see the result without building a spreadsheet or script.

Compare scenarios

Change one value at a time and rerun the calculation to understand what affects the result.

Automate repeated work

For developers — API access

Everything on this page is available programmatically. This section is for teams who want to wire it into their own systems; everyone else can just use the tool above.

API endpoint

POSThttps://api.kit.forhosting.com/str/longest-word

Prefer to automate it? One authenticated POST creates the task; the result comes back by webhook or a signed link. The same capability also runs here on the web, by email and from Telegram — and soon from our app too.

Call it from your stack

curl -X POST https://api.kit.forhosting.com/str/longest-word \
  -H "Authorization: Bearer $KIT_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text":"The quick brown fox jumps over the lazy dog."}'

const res = await fetch("https://api.kit.forhosting.com/str/longest-word", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.KIT_KEY}`,
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    "text": "The quick brown fox jumps over the lazy dog."
  })
});
const { task_id } = await res.json();

import os, requests

res = requests.post(
    "https://api.kit.forhosting.com/str/longest-word",
    headers={"Authorization": f"Bearer {os.environ['KIT_KEY']}"},
    json={
    "text": "The quick brown fox jumps over the lazy dog."
},
)
task_id = res.json()["task_id"]

<?php
$res = file_get_contents("https://api.kit.forhosting.com/str/longest-word", false, stream_context_create([
  "http" => [
    "method"  => "POST",
    "header"  => "Authorization: Bearer " . getenv("KIT_KEY") . "\r\nContent-Type: application/json",
    "content" => '{"text":"The quick brown fox jumps over the lazy dog."}',
  ],
]));
$task = json_decode($res, true);

body := bytes.NewBufferString(`{"text":"The quick brown fox jumps over the lazy dog."}`)
req, _ := http.NewRequest("POST", "https://api.kit.forhosting.com/str/longest-word", body)
req.Header.Set("Authorization", "Bearer "+os.Getenv("KIT_KEY"))
req.Header.Set("Content-Type", "application/json")
res, _ := http.DefaultClient.Do(req)

Example request

{
  "text": "The quick brown fox jumps over the lazy dog."
}

Example response

{
  "task_id": "tsk_a1b2c3d4e5f6a1b2c3d4e5f6",
  "type": "str.longest_word",
  "status": "queued",
  "_links": {
    "result": "/tasks/tsk_…/result"
  }
}

The API is asynchronous: the call returns a task_id immediately and the result arrives by webhook. Polling is capped at 1 req/s per task.

Pricing

Per request$0.002

Published price — no tokens, no invented credits. A failed task is never charged.

Limits

Errors

HTTP	Code	Meaning
`401`	`unauthorized`	Missing or invalid API key.
`402`	`insufficient_balance`	Your balance doesn't cover the task price.
`404`	`unknown_type`	That task type doesn't exist.
`429`	`rate_limited`	Too many requests. Use the webhook instead of polling.
