Company background
Currencyapi.com was started in 2019 by London-based software engineer Oli Girling, who originally built it to solve a currency data need in his own projects before opening it up publicly. It is now operated by House of Apis Ltd, a UK-registered company, and reports serving more than 10,000 clients with over 50 million requests handled per month.
The service is headquartered in London, United Kingdom, and positions itself as a straightforward, developer-friendly alternative to larger, more complex financial data providers.
Currency coverage and reliability
The API covers more than 170 world currencies and cryptocurrencies, with rate data aggregated from multiple financial data providers and international banks rather than a single source, and it reports 99.99 percent uptime over trailing 12-month periods.
Update frequency scales with subscription tier, ranging from daily updates on the free plan to 60-second updates on the Medium and Large paid tiers.
How the pricing tiers break down
The five tiers are Free (300 requests per month), Small at 9.99 USD per month (15,000 requests), Medium at 39.99 USD per month (600,000 requests), Large at 79.99 USD per month (1,700,000 requests), and a negotiable Custom plan for very high-volume or highly customized needs.
Higher tiers add features beyond raw request volume, including additional API keys, sandbox keys, team management, IP and URL whitelisting, and service level agreements on the top tiers.
