Currency Converter

Overview

Currency Converter works by analyzing the amount and currency provided and converting the currency rate. It uses advanced algorithms to convert the currency rate based on the amount and currency and returns the converted currency rate.

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.

if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);

package main

import (
	"fmt"
	"io"
	"net/http"
)

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/currencyconverter?value=1&from=USD&to=EUR", 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.

Parameters

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them.

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.

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.

Use cases

Multi-Currency Storefront Checkout

E-commerce platforms convert catalog prices to shoppers' local currencies and display current exchange rates at checkout before processing payment.

When employees submit foreign travel receipts, accounting software converts reimbursable expenses into company base currency using the exact exchange rate.

International Invoice Generation

Generate export invoices in foreign buyer currencies by calculating converted subtotals and showing whether the exchange rate moved up or down.
