Overview
The API polls live precious metal markets and delivers spot rates across troy ounces, grams, and kilograms. By default, responses return quotes in USD with 24-hour price change amounts and directional trends. Upgrading to a paid plan lets you convert prices into 172 world currencies, view 24-hour high and low ranges, or pull 24 hours of hourly price snapshots. Use it for today's platinum price per troy ounce (oz), per gram or per kilogram. The last 30 daily closes are stored too: paid plans get the 7- and 30-day change and the 30-day high, low, average and volatility, and daily=true returns the closes themselves.

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/platinumprice?currency=USD&hourly=true&daily=true" \
-H "x-api-key: your_api_key_here"const res = await fetch('https://api.apiverve.com/v1/platinumprice?currency=USD&hourly=true&daily=true', {
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/platinumprice?currency=USD&hourly=true&daily=true",
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/platinumprice?currency=USD&hourly=true&daily=true", 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 |
|---|---|---|
currencyOptionalPremium | string | The currency to get the price in default USD |
hourlyOptionalPremium | boolean | Include hourly price data for the past 24 hours |
dailyOptionalPremium | boolean | Include the daily closing price per ounce for the last 30 days |
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.

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. |
