About the Love Calculator API

Love Calculator works by analyzing the names provided and calculating the love compatibility percentage. It uses advanced algorithms to calculate the love compatibility between two names and returns the love compatibility percentage.

What people use it for

Dating App Icebreakers: To spark new conversations, dating apps show compatibility percentages between mutual matches before users send their first message.
Interactive Social Quizzes: Digital publishers generate viral couple tests where readers enter two names to receive a match percentage and shareable relationship summary.
Community Discord Bots: When server members run pairing commands, chat bots calculate instant compatibility percentages to create lighthearted engagement across social channels.
Holiday Marketing Campaigns: Drive seasonal traffic around Valentine's Day by letting shoppers test name pairings on promotional landing pages before revealing discount codes.

Ways to call it

Questions.

Common questions about the Love Calculator API.

Read the docs →

Is it cheap enough to calculate compatibility for every user match?

Yes. Each lookup costs 2 credits, which works out to about $0.0003 per call on the Starter plan, or $0.30 per 1,000 calculations. The Free plan includes 100 calculations each month, while Starter covers up to 100,000.

Is the detailed compatibility advice included on the Free plan?

No, the detailed compatibility analysis and advice field is a premium feature available only on paid plans. Free plan responses include the love percentage and summary text, while Starter and higher plans unlock the full written analysis.

What data does the calculation return for each pair?

The response provides the love compatibility percentage, an accompanying summary text, and the two submitted names. Upgrading to any paid plan also returns a detailed compatibility analysis and advice for the pair.

Can I submit full names or nicknames?

Yes. Both name parameters accept plain text strings, allowing you to pass first names, full names, or nicknames. The algorithm evaluates whatever name strings your users provide.

Can I use this for dating apps and social features?

Yes. Love Calculator is designed for entertainment use cases including dating apps, matchmaking widgets, social quizzes, and relationship games.

Request parameters — GET /v1/lovecalculator

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
`name1`Required	string	`John`	The first name to calculate love compatibility length 0-100
`name2`Required	string	`Jane`	The second name to calculate love compatibility length 0-100

Example request

1
2

curl "https://api.apiverve.com/v1/lovecalculator?name1=John&name2=Jane" \
  -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/lovecalculator

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": {
    "name1": "Jane",
    "name2": "John",
    "lovePercentage": "62%",
    "response": "You have good chemistry. Keep getting to know each other and see where it leads.",
    "additionalText": "The love percentage between Jane and John is 62%."
  }
}

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
`name1`	string	`"Jane"`	The first name provided for compatibility calculation
`name2`	string	`"John"`	The second name provided for compatibility calculation
`lovePercentage`	string	`"62%"`	Calculated love compatibility percentage between two names
`response`Premium	string	`"You have good chemistry. Keep getting to know each other and see where it leads."`	Detailed compatibility analysis and advice for the couple
`additionalText`	string	`"The love percentage between Jane and John is 62%."`	Additional information and summary about love percentage

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	Love Calculator 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.
