Quick answer
CurrencyFreaks - CurrencyFreaks wins for most builders because its free tier is larger and more useful for testing real integrations, while Currencyapi.com only makes sense if you are happy with a very small request cap and can live with private-use limits.
How the free tiers compare
These two free tiers look similar on paper because both are REST FX APIs with HTTPS and no card required, but they differ in how far you can actually go before paying. Currencyapi.com gives you 300 requests per month, one API key, private use only, and 10 requests per minute, so it is best as a tiny proof of concept or a narrow internal tool. CurrencyFreaks gives you 1,000 calls per month, SSL, and a broader starter surface, but its free plan is still limited by 24-hour updates and USD as the base currency. The paid ladders are also different in shape: Currencyapi.com jumps from very small to 15K requests at $9.99, then scales mostly by larger flat tiers, while CurrencyFreaks keeps the same flat structure but adds more call volume and fresher data at each step.

| SSL / HTTPSBoth include encrypted access. | HTTPS encryption | SSL encryption |
After you outgrow the free tier
Both products use flat monthly pricing on their first paid tiers, so the main difference is how quickly you outgrow the free plan rather than how the bill ramps. Currencyapi.com starts at $9.99/mo for 15,000 requests, then jumps to $39.99/mo and $79.99/mo. CurrencyFreaks also starts at $9.99/mo for 15K calls, then goes to $49.99/mo and $99.99/mo. For small teams, the first paid tier is the same price, but CurrencyFreaks gives a larger free tier, while Currencyapi.com is cheaper at the mid and upper tiers.

When to pick each one
Pick Currencyapi.com when…
- You only need a very small internal prototype with up to 300 requests per month.
- You want historical and latest rates on a tiny free allowance and do not need commercial use.
- You are validating whether Currencyapi.com fits your stack before paying, and your traffic is low enough to stay under 10 requests per minute.
- You prefer a free plan that is simple and strict, with one API key and a clear cap.
Pick CurrencyFreaks when…
- You need more breathing room for development, testing, or a small demo and 1,000 calls per month is more realistic.
- You want a free tier that is easier to use for a real integration, not just a toy proof of concept.
- You may later need more base-currency flexibility, since the paid path starts unlocking all base currencies.
- You expect to compare update freshness across plans and want a ladder that moves from 24-hour updates to hourly, then 10-minute, then 60-second updates.
Bottom line
For the most common builder use case, CurrencyFreaks is the better free-tier starting point because 1,000 monthly calls is enough to build and test something real without hitting the wall immediately. If you only need a tiny internal prototype, Currencyapi.com is fine, but its 300-request limit and private-use restriction make it feel tighter from day one. Once you pay, both start at $9.99/mo, but CurrencyFreaks keeps the larger free tier advantage while Currencyapi.com stays a bit cheaper at higher flat tiers.
