Line Sorter API Reference

Overview

Perfect for organizing lists, cleaning up data files, and alphabetizing content with precise control over sorting behavior.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

POSThttps://api.apiverve.com/v1/linesorter

curl -X POST https://api.apiverve.com/v1/linesorter \
  -H "x-api-key: your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{
  "lines": [

    "An apple a day keeps the doctor away",
    "banana",
    "Cherry blossoms bloom in spring",
    "date"
  ],
  "order": "asc",
  "caseSensitive": false

	fmt.Println(string(out))
}

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Parameters

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them.

Parameter	Type	Description
`lines`Required	array	Array of text lines to sort (max 10,000)
`order`Optional	string	Sort order `ascdesc` default asc
`caseSensitive`Optional	boolean	Enable case-sensitive sorting

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "sorted": [
      "An apple a day keeps the doctor away",
      "banana",
      "Cherry blossoms bloom in spring",
      "date",
      "The quick brown fox jumps over the lazy dog"
    ],
    "lineCount": 5,
    "order": "asc",
    "caseSensitive": false
  }
}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Field	Type	Example	Description
`sorted`	array	`[An apple a day keeps the doctor away, ...]`	Array of sorted text lines
`lineCount`	number	`5`	Total number of lines sorted
`order`	string	`"asc"`	Sort order that was applied
`caseSensitive`	boolean	`false`

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted	A key restriction or IP allow-list; see key scoping.
`429`	Rate limited, or out of credits	Read `error` to tell them apart; see rate limits.

Use cases

List Organization: Sort and organize lists alphabetically for better readability and data management
Data Cleanup: Clean up and alphabetize data files with customizable sorting options
Content Sorting: Sort text content with case-sensitive or case-insensitive options
File Processing: Process and organize large text files with up to 10,000 lines
