Plans and tiers
Currency-api offers several distinct pricing tiers, each tailored to different usage patterns and feature requirements. These plans primarily differentiate by the number of monthly API requests, the frequency of data updates, and access to advanced features such as historical data and time-series endpoints. All paid plans include access to over 170 world currencies and support for various programming languages via SDKs, including PHP, Python, and JavaScript.
Below is a summary of the available plans:
| Plan | Monthly Price | Monthly Requests | Refresh Rate | Key Features | Best For |
|---|---|---|---|---|---|
| Free | $0 | 3,000 | 10 minutes | 100 API calls/day, 170+ currencies | Personal projects, basic testing |
| Basic | $9.99 | 10,000 | 1 minute | Historical data, 170+ currencies | Small applications, e-commerce price conversion |
| Professional | $29.99 | 100,000 | 1 minute | Time-series data, advanced historical queries | Growing applications, financial dashboards |
| Business | $99.99 | 1,000,000 | 30 seconds | High-volume usage, priority support | Large-scale e-commerce, enterprise integrations |
| Enterprise | Custom | Custom | 60 seconds or less | Dedicated infrastructure, SLA, custom features | Mission-critical financial systems, large corporations |
Each plan offers increasing request limits and enhanced features, ensuring that users can select a tier that aligns with their operational scale and data requirements. The Enterprise plan provides a customized solution for organizations with specific infrastructure or data needs, often involving direct consultation with the Currency-api team.
Free tier and limits
Currency-api provides a free tier designed for developers to test the API and for personal or small-scale projects with limited currency exchange rate needs. This tier allows up to 3,000 API requests per month, with a daily limit of 100 API calls per day. The data refresh rate for the free tier is 10 minutes, meaning exchange rates are updated from their sources every ten minutes. This refresh interval is suitable for applications where immediate real-time accuracy is not critical, such as displaying general currency conversions on a personal blog or a simple utility tool.
Key limitations of the free tier include:
- Monthly requests: 3,000 requests. Exceeding this limit requires an upgrade to a paid plan.
- Daily calls: 100 API calls. This daily cap helps manage server load and prevents abuse.
- Refresh rate: 10 minutes. This is the longest refresh interval offered by Currency-api.
- Feature access: Primarily limited to current exchange rates. Access to historical data, time-series data, and other advanced endpoints is generally restricted to paid plans.
The free tier serves as an accessible entry point for developers to integrate currency conversion functionalities without an upfront financial commitment. For applications requiring more frequent updates or higher request volumes, upgrading to a paid plan becomes necessary, as detailed on the Currency-api pricing page.
Real-world cost examples
Understanding Currency-api's pricing involves considering typical usage patterns. Here are a few scenarios illustrating potential costs:
Scenario 1: Small E-commerce Store
A small online store needs to display product prices in multiple currencies based on the user's location. The store updates prices once per hour for approximately 500 products, resulting in 500 API calls per hour. Over a month (30 days), this totals 500 calls/hour * 24 hours/day * 30 days/month = 360,000 API requests/month.
- Plan required: Professional ($29.99/month), which includes 100,000 requests/month. This scenario would exceed the Professional plan.
- Actual plan needed: Business ($99.99/month), providing 1,000,000 requests/month.
- Monthly cost: $99.99.
Scenario 2: Personal Finance Tracker
A personal finance application for an individual user checks exchange rates daily for 10 different currencies. The application makes one API call per day to fetch these rates. Over a month, this amounts to 1 call/day * 30 days/month = 30 API requests/month.
- Plan required: Free tier.
- Monthly cost: $0.
Scenario 3: Financial News Website
A financial news website displays real-time exchange rates for major currency pairs on its homepage, updating every minute. Assuming 10 currency pairs are displayed, and the page loads 100,000 times per day (each load potentially triggering an API call), this results in 100,000 loads/day * 30 days/month = 3,000,000 API requests/month.
- Plan required: This usage significantly exceeds the Business plan's 1,000,000 requests/month.
- Actual plan needed: Enterprise plan (custom pricing).
- Monthly cost: Custom, negotiated with Currency-api.
Scenario 4: Developer Testing
A developer is building a prototype that requires occasional currency conversions during development and testing, making about 50 API calls per day for a few weeks.
- Plan required: Free tier.
- Monthly cost: $0 (within the 100 daily calls and 3,000 monthly requests).
These examples illustrate how specific usage patterns directly influence the most suitable pricing tier and overall monthly expenditure. For high-volume or specialized needs, direct consultation for an Enterprise plan is recommended to ensure optimal cost-effectiveness and performance, as detailed in the Currency-api documentation.
How the pricing compares
When evaluating Currency-api's pricing, it is useful to compare it against other providers in the currency exchange rate API market. Key competitors include Open Exchange Rates, fixer.io, and ExchangeRate-API. While pricing models often share similarities, such as tiered subscriptions based on request volume, differences emerge in free tier generosity, refresh rates, and feature sets.
- Open Exchange Rates: Offers a free tier with 1,000 requests/month and a 1-hour refresh rate. Paid plans start at $12/month for 10,000 requests with a 10-minute refresh. Currency-api's free tier offers more requests (3,000) but a longer refresh rate (10 minutes) compared to Open Exchange Rates' free tier. At the basic paid level, Currency-api's $9.99 for 10,000 requests with a 1-minute refresh is generally more competitive on refresh speed than Open Exchange Rates' equivalent. For more details on Open Exchange Rates' pricing, refer to their developer plans.
- fixer.io: Provides a free plan with 1,000 requests/month and daily updates. Paid plans start at €14/month (approximately $15 USD) for 10,000 requests with 60-minute updates. Currency-api's free tier has a higher request limit and a faster refresh rate (10 minutes vs. daily) than fixer.io's free offering. At the entry-level paid tier, Currency-api offers a significantly faster refresh rate (1 minute vs. 60 minutes) for a comparable request volume and slightly lower price.
- ExchangeRate-API: Offers a free tier with 1,500 requests/month and a 24-hour refresh rate. Their paid plans begin at $14/month for 10,000 requests with a 10-minute refresh. Currency-api's free tier again provides more requests and a faster refresh rate. For paid plans, Currency-api's Basic plan is less expensive ($9.99 vs. $14) while offering a significantly faster refresh rate (1 minute vs. 10 minutes) for the same request volume. Additional information can be found on the ExchangeRate-API pricing page.
Overall, Currency-api tends to offer a more generous free tier and more competitive refresh rates at its entry-level paid plans compared to several alternatives. The choice between providers often depends on the specific balance required between request volume, data freshness, and budget. Developers evaluating these services might also consider factors such as API documentation quality and community support, which can influence overall developer experience, as noted by sources like Google's API design principles on developer experience.
