Exchange Rate

Get exchange rate between two currencies

OperationalCredits 2 per callp50 162msFinanceStar

Overview

An FX rate API for live forex rates, in one call: pass two currency codes as parameters to receive the current conversion multiplier and an ISO 8601 timestamp showing when the rate refreshed. The response covers over 170 currencies. Each response names both currencies. Paid plans also return the inverse rate for reverse conversions without a second call, and how far the pair has moved over the last day, 7 days, 30 days and year, measured from the rate's date, so a historical lookup reports the moves leading up to that day. The last 30 daily closes are stored per currency, so paid plans also get the pair's 30-day high, low, average and volatility, and history=true returns the closes themselves. On live lookups, hourly=true adds the rate for each of the last 24 hours.

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.

GEThttps://api.apiverve.com/v1/exchangerate
curl "https://api.apiverve.com/v1/exchangerate?currency1=USD&currency2=EUR&date=2025-06-02&history=true&hourly=true" \
  -H "x-api-key: your_api_key_here"

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.

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.

Parameters

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

ParameterTypeDescription
currency1RequiredstringThe first currency you want to get the exchange rate for
currency2RequiredstringThe second currency you want to get the exchange rate for
dateOptionalPremiumstringOptional past date (YYYY-MM-DD) to use that day's closing rates instead of live rates. History runs from 1999-01-04 for about 30 major currencies and covers every supported currency from March 2024. A day with no rates, such as a weekend or holiday, uses the last close before it.
historyOptionalPremiumbooleanInclude the pair's daily closing rate for the last 30 days
hourlyOptionalPremiumbooleanInclude the pair's rate for each of the last 24 hours (live rates only, not with date)
date

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.

StatusMeaningWhat to do
