Pricing overview
Exchangeratesapi.io operates on a subscription-based pricing model, primarily determined by the number of API requests made per month. The service includes a free tier for low-volume usage, with multiple paid tiers designed to accommodate varying application sizes and operational demands. Each tier provides access to different features, such as increased request limits, historical data windows, and SSL encryption enforcement. The pricing structure is detailed on the Exchangeratesapi.io pricing page.
The API provides real-time and historical currency exchange rates, supporting various use cases like financial dashboards, e-commerce pricing adjustments, and travel applications. Developers interact with the service through a REST API that returns JSON responses, requiring an API key for authentication. This approach aligns with common practices for managing access to commercial web services, as seen in other API providers like Stripe's API documentation.
Plans and tiers
Exchangeratesapi.io offers several plans, each tailored to different usage requirements. These plans typically differentiate by the monthly request allowance, the scope of historical data access, and the availability of specific API endpoints like time-series or fluctuation data. All paid plans include SSL encryption, which is a standard security practice for data transmission over the internet, as recommended by organizations like the World Wide Web Consortium (W3C).
The core plans include:
- Basic Plan: Aimed at small-scale applications or early-stage development beyond the free tier.
- Professional Plan: Suitable for growing applications requiring higher request volumes and more extensive historical data access.
- Enterprise Plan: Designed for large organizations needing very high request limits, comprehensive historical data, and potentially custom solutions.
A comparison of the standard plans is provided below, outlining their key features and limitations as published on the official pricing page.
| Plan | Monthly Price (approx.) | Monthly Requests | Historical Data (Years) | Features | Best For |
|---|---|---|---|---|---|
| Free | $0 | 250 | 1 | Latest rates, base currency switch | Testing, very low-volume personal projects |
| Basic | $14.99 | 10,000 | 2 | All Free features, SSL encryption, up to 10 foreign currencies | Small businesses, early-stage startups |
| Professional | $69.99 | 100,000 | 5 | All Basic features, time-series, fluctuation data, up to 25 foreign currencies | Medium-sized applications, financial dashboards |
| Enterprise | Custom | Custom (high volume) | Full Historical | All Professional features, dedicated support, unlimited currencies | Large enterprises, high-traffic financial platforms |
Free tier and limits
Exchangeratesapi.io provides a free tier that allows up to 250 API requests per month. This tier is intended for developers to test the API's functionality, integrate it into proofs-of-concept, or power applications with minimal currency exchange rate requirements. The free tier includes access to the latest exchange rates and allows for switching the base currency. It also provides historical data for up to one year. Users on the free tier must ensure their applications remain within the 250-request limit to avoid service interruptions or the need to upgrade to a paid plan. Details on the free tier's capabilities are outlined on the Exchangeratesapi.io documentation page.
Key limitations of the free tier:
- Request Volume: Capped at 250 requests per month. Exceeding this limit typically requires an upgrade.
- Historical Data: Access to historical rates is limited to the most recent year. Deeper historical data necessitates a paid subscription.
- Feature Access: Advanced features such as time-series data, fluctuation data, and conversion endpoints are generally reserved for paid plans.
- Base Currency Options: While it allows switching the base currency, some more dynamic or complex base currency operations might be restricted compared to higher tiers.
Real-world cost examples
Understanding the actual cost of using Exchangeratesapi.io involves estimating monthly API request volume and aligning it with the appropriate plan. The primary factor influencing cost is the number of API calls an application makes within a 30-day period.
Scenario 1: Small E-commerce Widget
An e-commerce website features a currency converter widget that makes one API call per page load for visitors browsing in a foreign currency. Assuming 5,000 unique international visitors per month who use the converter, this totals 5,000 requests. Additionally, the site updates its product prices once daily in a foreign currency, adding 30 requests (30 days * 1 update/day). The total monthly requests would be approximately 5,030.
- Cost: This usage fits within the Basic Plan (10,000 requests/month) at around $14.99 per month.
Scenario 2: Financial Dashboard for Traders
A financial dashboard used by active traders fetches real-time exchange rates every 15 minutes for 10 different currency pairs. This happens 24 hours a day, 7 days a week. Additionally, it makes 100 historical data requests daily for analysis.
- Real-time requests: (60 minutes / 15 minutes) * 24 hours * 30 days * 10 currency pairs = 4 * 24 * 30 * 10 = 28,800 requests/month.
- Historical requests: 100 requests/day * 30 days = 3,000 requests/month.
- Total monthly requests: 28,800 + 3,000 = 31,800 requests.
- Cost: This usage would require the Professional Plan (100,000 requests/month) at around $69.99 per month, as it significantly exceeds the Basic Plan's limits.
Scenario 3: Global Travel Application
A popular global travel application features dynamic pricing in local currencies and provides currency conversion tools, generating a high volume of requests. It processes an average of 1,500,000 currency-related API calls per month, including historical trend analysis for flight and hotel searches.
- Cost: This volume surpasses the Professional Plan. The application would require a customized Enterprise Plan due to the high request volume and potential need for dedicated support and full historical data access. The cost would be negotiated directly with Exchangeratesapi.io.
How the pricing compares
When evaluating Exchangeratesapi.io's pricing, it's useful to compare it against other providers in the currency exchange rate API market. Key alternatives include Open Exchange Rates, Fixer.io, and Currencyapi.com. The comparison often focuses on the cost per request, available features at different tiers, and the breadth of supported currencies and data types.
- Open Exchange Rates: Offers a similar tiered model, with a free plan for 1,000 requests/month (more generous than Exchangeratesapi.io's 250) and paid tiers starting around $12/month for 10,000 requests. It provides access to real-time and historical data.
- Fixer.io: Also owned by APILayer (part of Idera, Inc.), Fixer.io shares a nearly identical pricing structure and feature set with Exchangeratesapi.io. Its free tier is also 250 requests/month, and its basic paid plan starts at $14.99/month for 10,000 requests. The choice between Exchangeratesapi.io and Fixer.io often comes down to specific branding or legacy integration preferences, given their shared backend and pricing model.
- Currencyapi.com: Features a free plan with 3,000 requests/month and paid plans starting at around $10/month for 10,000 requests. It emphasizes robust historical data and a wide range of supported currencies.
Exchangeratesapi.io's starting paid tier at $14.99 for 10,000 requests is competitive within the market. Its free tier is less generous than some alternatives in terms of request volume but remains sufficient for initial testing and very light use. The availability of time-series and fluctuation data in higher tiers offers value for financial applications requiring detailed analysis. Developers often weigh the specific features, reliability, and ease of integration against the precise pricing points when selecting an API provider for currency exchange rates.
