Nowadays, APIs (tool Programming Interface) are required to interact with almost any tool.
You may ask, Why?
Well, its because APIs are a great way to securely and selectively transfer data to a third party.
By selectively, I mean you dont need to expose all of your data to the requesting party.
you could abstract some of it and share only what you want to.
But theres a catch.
For significantly complex applications, the API can become cumbersome and tedious to deal with.
With over 100+ endpoints, API users may find it difficult to access data in a structured way.
The SDK generated by Speakeasy focuses on these key aspects to improve the developer experience.
Key Features:
It also helps you create terraform providers to level up your API infrastructure.
They provide a free tier for hobby and personal projects and an enterprise plan for businesses.
It offers a 14-day free trial but does not include a free tier.
For businesses and enterprises, it follows a custom pricing model.
Fern
Fernis specifically designed to generate SDK for your API.
SDKs are customizable, which allows you to add custom logic to them.
With the pro plan, you’re free to publish SDKs to GitHub repos and sync to Postman.
Liblab
Liblabis a language-native, SoC-2-compliant SDK generator with built-in authentication, error handling, and security.
Hooks are used to inject custom code into your SDK generation pipeline.
Liblab provides an entire framework known asHooks Frameworkto do so.
Its free for personal and hobby projects allowing you to explore Liblab.
Konfig
Konfigcan regenerate the SDK whenever you make a change to your API spec.
Writing test cases and input validation is not a thing for you to worry about.
it’s possible for you to schedule a demo to start exploring it.
However, currently, it only supports Swagger 2.0 spec at the time of writing this article.
The list of all specs that will be supported in the future is listed under thisREADMEfile.
And there is still no support for major specifications such as Postman.
REST United
REST Unitedis an SDK generator to generates SDKs in 9 different programming languages.
The documentation is also customizable as per your needs.
It offers a 14-day free trial for you to explore the generator with up to 5 endpoints per API.
The enterprise plan is based on a custom pricing model.
API definition files can be used to create libraries in popular languages like Java, Scala, and Ruby.
It supports over 40 programming languages and can also generate server boilerplate code for up to 20 programming languages.
Its enterprise plan allows a minimum of 15 designers and 30 consumers.
Kiota can generate code that enables autocomplete in your IDE to help in API resource and method discovery.
Also, it enables full access to HTTP capabilities.
Imagine having 10 different endpoints that will be called from a specific component in the user interface.
Will it not be tedious for those writing code to call different endpoints?
You dont want your customers to use the API with bad practices.
Error messages are essential when a new developer team is using your API.
If they do something unexpected, they should be able to find the root cause.
And SDKs can help you generate better and more comprehensive error messages.
so that make an API call, you should probably implement an HTTP request handler.
The SDK implementation can take care of the HTTP version, headers, timeouts, etc.
SDK can be used to enforce validations, for example, mandatory function parameters and their data types.
This eventually leads to more customers because they find your API easy to use.
When picking an SDK generation tool, look out for language support as well as API specification support.
