Inflation Rate

Overview

Inflation Rate works by aggregating consumer price index data from the World Bank for over 180 countries. It provides both the annual inflation rate (year-over-year percentage change in consumer prices) and the CPI index value (base year 2010 = 100). Data is refreshed daily.

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.

package main

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

func main() {
	req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/inflation?country=US&year=2023", nil)
	req.Header.Set("x-api-key", "your_api_key_here")

	res, err := http.DefaultClient.Do(req)
	if err != nil {

}

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.

{
  "status": "ok",
  "error": null,
  "data": {
    "country": "US",
    "countryName": "United States",
    "year": 2023,
    "inflationRate": 4.12,
    "cpiIndex": 139.81,
    "cpiBaseYear": 2010,
    "lastUpdated": "2026-02-05T04:00:00.000Z"
  }
}

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

Salary Adjustment Calculations

Compensation software calculates real wage growth across international offices by adjusting regional salaries against annual inflation figures.

Cross-Border Contract Indexing

When drafting multi-year vendor agreements, legal teams index payment schedules to annual consumer price changes for each supplier's country.

Portfolio Return Deflation

Wealth management dashboards subtract local consumer price index shifts from gross portfolio returns to present accurate purchasing power gains.

Purchasing Power Modeling

To forecast global product pricing, revenue teams evaluate relative purchasing power trends using annual price change rates and index values.
