currencylayer Alternative: AllRatesToday Currency API

currencylayer caps the free tier at 100 requests, locks it to a USD base, and updates hourly on lower plans. AllRatesToday gives you real-time rates, any base currency, and low EUR pricing.

currencylayer is one of apilayer's flagship currency products and a dependable choice for USD-based, hourly-refresh use cases. But its free tier is tight — around 100 requests per month, USD base only — real-time updates are reserved for the higher plans, and pricing climbs steeply as your volume grows. AllRatesToday is a modern alternative with real-time data on every plan, any base currency, and smaller pricing steps. (We've also written a detailed AllRatesToday vs currencylayer breakdown.)

Why teams switch from currencylayer to AllRatesToday

1. Real-time on every plan, not just the top tiers

currencylayer refreshes hourly on the free and lower paid tiers, with real-time reserved for Professional and above. In a volatile session a major pair can move noticeably within an hour — stale enough to matter at a checkout or in a trading-adjacent dashboard. AllRatesToday updates every 60 seconds on all plans, free included.

2. Any base currency from day one

The USD-base lock on currencylayer's lower plans means EUR- or GBP-centric apps cross-divide on the client, which introduces rounding and extra handling. AllRatesToday lets any plan use any of 160+ currencies as the source.

3. Gentler pricing curve

currencylayer's pricing steps up steeply as volume grows. AllRatesToday's plans go €4.99 → €9.99 → €49.99 per month (5,000 / 10,000 / 100,000 requests), so you buy roughly what you use. Full details on the pricing page, and our currencylayer cost breakdown walks through their tiers.

4. Header auth instead of keys in URLs

currencylayer authenticates with an access_key query parameter, which tends to leak into logs, analytics, and pasted URLs. AllRatesToday uses a standard Authorization: Bearer header.

Official central bank rates — the part no market feed offers

Beyond live market rates, AllRatesToday serves the official published rates of 54 central banks and three tax authorities (HMRC, US Treasury, Swiss BAZG) under the same API key — the ECB reference rate for EU accounting, the Banxico FIX that legally settles USD obligations in Mexico, HMRC's monthly customs rates, and more, each under the bank's own publication date. If your workload ever touches invoicing, accounting, customs, or audit, this is the difference that matters: a market feed answers "what does the pair trade at?", while compliance asks "which rate were you required to use?" (Our central bank API comparison covers the landscape.)

Drop-in code example

The endpoint families map closely — latest, historical, convert — so migration is mostly a URL and auth change:

// Before — currencylayer (access_key in the query string)
fetch('http://api.currencylayer.com/live?access_key=YOUR_KEY&source=USD&currencies=EUR,GBP')

// After — AllRatesToday (Bearer header, any source currency)
fetch('https://allratestoday.com/api/v1/rates?source=EUR&target=USD,GBP', {
  headers: { Authorization: 'Bearer art_live_xxxxx' }
})
  .then(r => r.json())
  .then(rows => console.log(rows));
