Anagram Detector API

GET

Verify whether two words or phrases are true anagrams.

Anagram Detector checks whether two words or phrases are anagrams of each other. Submit two strings to receive a true or false match verdict, cleaned comparison text, and character counts with options to ignore letter case and spaces.

About the Anagram Detector API

Anagram Detector works by normalizing both texts according to specified options, comparing character frequencies, and calculating similarity metrics. Returns detailed analysis including common characters, unique characters, and percentage similarity.

What people use it for

Word Games: Validate anagrams in word puzzles, Scrabble, and anagram-based games
Cryptography: Analyze anagram-based ciphers and cryptographic puzzles
Linguistics: Study anagram relationships in language research and text analysis
Educational Apps: Create interactive tools for teaching anagrams and word patterns

Ways to call it

One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

JSON: Default REST response
XML: Markup format
YAML: Human-readable
CSV: Tabular export
GraphQL: Query language
MCP: For AI agents

Questions.

Common questions about the Anagram Detector API.

Read the docs →

Is it cheap enough to check anagrams on every user guess?

Yes. Each comparison costs 2 credits, which works out to about $0.0003 per call or $0.30 per 1,000 calls on the Starter plan. The Free plan includes 100 checks each month for testing before upgrading.

Do I get similarity scoring and sorted letters on the Free plan?

No. The Free plan reports whether texts are anagrams along with their cleaned lengths, but the similarity percentage score and sorted letter lists require any paid plan, starting with Starter.

Can it compare multi-word phrases with mixed casing and spaces?

Yes. By default, both casing and spaces are ignored during comparison, so phrases like debit card and bad credit match automatically. You can toggle these options if your application requires strict case or whitespace matching.

Can I evaluate near-matches if two inputs are not exact anagrams?

Yes, on paid plans. The endpoint computes a similarity percentage alongside the boolean check. This lets your application score partial matches and award partial credit in word puzzles even when letters do not align completely.

What happens when two submitted texts have different lengths?

The API marks the anagram result as false while still returning the individual lengths and cleaned text strings. If you are on a paid plan, it also calculates the similarity score across the mismatched inputs.

Request parameters — GET /v1/anagramdetector

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`text1`Required	string	`listen`	The first text to compare
`text2`Required	string	`silent`	The second text to compare

Optional

Parameter	Type	Example	Description
`ignorecase`Optional	boolean	`true`	Ignore case when comparing (default: true) default true
`ignorespaces`Optional	boolean	`true`	Ignore spaces when comparing (default: true) default true

Example request

1
2

curl "https://api.apiverve.com/v1/anagramdetector?text1=listen&text2=silent&ignorecase=true&ignorespaces=true" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.

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.

Response — GET /v1/anagramdetector

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Sample response

{
  "status": "ok",
  "error": null,
  "data": {
    "text1": "listen",
    "text2": "silent",
    "is_anagram": true,
    "cleaned_text1": "listen",
    "cleaned_text2": "silent",
    "sorted_text1": "eilnst",
    "sorted_text2": "eilnst",
    "length_text1": 6,
    "length_text2": 6,
    "similarity_percentage": 100
  }
}

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
`text1`	string	`"listen"`	The first input text provided for comparison
`text2`	string	`"silent"`	The second input text provided for comparison
`is_anagram`	boolean	`true`	Boolean indicating whether the texts are anagrams
`cleaned_text1`	string	`"listen"`	First text after applying ignore case and space options
`cleaned_text2`	string	`"silent"`	Second text after applying ignore case and space options
`sorted_text1`Premium	string	`"eilnst"`	Characters of first text sorted alphabetically
`sorted_text2`Premium	string	`"eilnst"`	Characters of second text sorted alphabetically
`length_text1`	number	`6`	Character count of the first text
`length_text2`	number	`6`	Character count of the second text
`similarity_percentage`Premium	number	`100`	Percentage similarity score between the two texts

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	Anagram Detector calls	Per 1,000 calls
Free	Free	200	100	Free
Starter	$29.99	200,000	100,000	$0.30
Pro	$99.99	1,000,000	500,000	$0.20
Mega	$299.99	4,000,000	2,000,000	$0.15

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
