Integrate FastTools services into your applications with our powerful RESTful APIs. Our developer-friendly tools are free to use, well-documented, and built for performance. Explore our available APIs and start building today.
Our APIs are built on a robust, scalable infrastructure, ensuring high availability and low latency for your applications.
Get started for free. Our generous free tiers are designed to help developers experiment and build without financial barriers.
We follow industry best practices for security. All API traffic is encrypted, and we use standard RESTful conventions.
Each API comes with clear, detailed documentation, code samples, and live testing capabilities to get you up and running in minutes.
We are continuously developing a suite of APIs to provide programmatic access to our most popular tools. Each API is designed to be simple, efficient, and easy to integrate.
Our free Currency Conversion API is designed for simplicity and ease of use, providing real-time exchange rates for over 150 currencies. To get started, you don't need an API key—you can begin making requests immediately. The API provides a simple GET endpoint for fetching conversion rates. For example, to get the latest conversion rate from USD to EUR, you would make a request to an endpoint like /api/v1/currency/convert?from=USD&to=EUR&amount=1. The API will return a clean JSON response containing the requested rate and the converted amount. This straightforward design makes it incredibly easy to integrate into any application, from e-commerce sites to financial dashboards. The data is updated regularly to ensure you're always working with the most current exchange rates available.
Our APIs are built on REST (Representational State Transfer), an architectural style that has become the standard for web-based APIs. This means our APIs are predictable, scalable, and easy to understand. We adhere to core RESTful principles, such as using standard HTTP methods (GET, POST, etc.) to perform actions, and structuring our URLs to represent resources in a logical way. For example, a GET request to /api/v1/tools would retrieve a list of available tools. This stateless design ensures that every request contains all the information needed to process it, making our APIs highly reliable and easy to debug. By following these best practices, we provide a developer-friendly experience that reduces the learning curve and allows you to focus on building your application, not on deciphering a complex API.
We are committed to building a comprehensive and powerful API platform for developers. The APIs currently available are just the beginning. Our roadmap includes the introduction of API keys to provide a more personalized and secure experience, allowing for higher rate limits and access to more advanced features. We are also actively working on exposing more of our popular tools through new endpoints. Soon, you'll be able to programmatically interact with our image editing tools, PDF utilities, and data converters. We believe in the power of community-driven development, so we actively encourage you to suggest new APIs or features that would help you in your projects. Your feedback will directly shape the future of our platform as we work to become the go-to source for free, reliable developer APIs.
