CurrencyLayer Alternative: CurrencyRest (Fiat + Crypto, Free Full Access)

Looking for a CurrencyLayer alternative? Whether you've hit CurrencyLayer's plan limits, need cryptocurrencies alongside fiat, or want a free tier you can actually build on, this guide covers what to compare and why developers move to CurrencyRest.

Why developers look for an alternative

CurrencyLayer is a solid fiat exchange-rate API, but teams commonly outgrow it for a few reasons:

• Fiat only — no cryptocurrencies, so crypto pricing means a second vendor.
• Currency access gated by plan — some pairs and features sit behind higher tiers.
• Free tier limits — enough to try, not always enough to validate a real integration.

CurrencyRest vs CurrencyLayer

	CurrencyRest	CurrencyLayer
Fiat currencies	108	~168
Cryptocurrencies	94	—
Data sources	9 (central banks, markets, exchanges) with failover	Aggregated
Free tier	Full access, all pairs, 300 req/mo	Limited
Source selection	Yes (source=ecb, etc.)	No
Starting paid price	$9/mo	Varies
Historical data	Yes (90 days)	Yes

The headline difference: CurrencyRest is universal (fiat + crypto in one API) and its free plan gives full access to every pair — you only pay for more volume, never to unlock currencies.

Migrating is straightforward

Both are REST + JSON with header authentication. A typical CurrencyLayer live call:

GET https://api.currencylayer.com/live?access_key=KEY&currencies=EUR,GBP&source=USD

The CurrencyRest equivalent:

curl "https://api.currencyrest.com/api/v1/rates?base=USD" \
  -H "X-API-Key: your_api_key"

Responses are clean JSON grouped into fiat and crypto, with a source field so you always know the origin of each rate. Need a single pair? Use /convert?from=USD&to=EUR&amount=100.

What you gain

• Crypto without a second vendor — 94 cryptocurrencies from Binance and CoinGecko.
• Central-bank accuracy — ECB, Fed, BoE, BoJ for fiat, with automatic failover.
• A real free tier — test every currency pair with no restrictions, 300 requests/month, no credit card.
• Transparent sources — pin a provider or let CurrencyRest choose and fail over.

FAQ

Is CurrencyRest free? Yes — the free plan includes all 202 currencies and every pair, capped at 300 requests/month.

Does CurrencyRest support crypto like CurrencyLayer's crypto endpoint? CurrencyRest includes 94 cryptocurrencies natively in the same API as fiat, with cross-rates.

Can I keep my current architecture? Yes — it's a drop-in REST/JSON API with header auth; most integrations migrate in an afternoon.
