Overview
Tip Calculator works by calculating tip amounts based on percentage and bill total, then dividing by the number of people. Returns detailed breakdowns including common tip amounts for easy comparison and decision-making.
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.
curl "https://api.apiverve.com/v1/tipcalculator?amount=100&percentage=18&people=4¤cy=USD" \
-H "x-api-key: your_api_key_here"const res = await fetch('https://api.apiverve.com/v1/tipcalculator?amount=100&percentage=18&people=4¤cy=USD', {
headers: { 'x-api-key': 'your_api_key_here' },
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const { data } = await res.json();
console.log(data);import requests
res = requests.get(
"https://api.apiverve.com/v1/tipcalculator?amount=100&percentage=18&people=4¤cy=USD",
headers={"x-api-key": "your_api_key_here"},
timeout=15,
)
res.raise_for_status()
print(res.json()["data"])package main
import (
"fmt"
"io"
"net/http"
)
func main() {
req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/tipcalculator?amount=100&percentage=18&people=4¤cy=USD", nil)
req.Header.Set("x-api-key", "your_api_key_here")
res, err := http.DefaultClient.Do(req)
if err != nil {
panic(err)
}
defer res.Body.Close()
out, _ := io.ReadAll(res.Body)
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.
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 in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.
| Parameter | Type | Description |
|---|---|---|
amountRequired | number | The bill amount before tip range 0–∞ |
percentageOptional | number | Tip percentage default 15 · range 0–100 |
peopleOptional | integer | Number of people to split the bill default 1 · range 1–∞ |
currencyOptional | string | Currency code for display default USD |
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.

}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 |
|---|---|---|---|
bill_amount | number | 100 | Original bill amount before tip calculation |
tip_percentage | number | 18 | Tip percentage applied to the bill |
tip_amount | number | 18 | Calculated tip amount in currency |
total_amount | number | 118 | Total amount including bill and tip |
currency | string | "USD" | Currency code used for amounts |
split_between | number | 4 | Number of people bill is split among |

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. |
