Hire REST API developers

The cost to hire an REST API developer is on average $65 per hour, though there is a large range of hourly prices for developers who creates and integrates REST API. The total hourly rate range is $56/h and goes up to $76/h, according to Glassdoor.com

The cost of an REST API call varies between providers, the type of call in question, and how much their services you use. The prices may go as low as $0.01 per call, but most of the APIs have free tiers that come with limited numbers of calls. It’s best to check their website for pricing details from an API provider.

The price of a custom API differs depending on the complexity, functionality, the rate of the development team, and time. Less complex APIs are done within $2,000 to $10,000 for light tasks, which take 1–2 weeks to perform. More complex APIs are done from $10,000 up to $50,000 or even more and take several weeks or months. Besides, hosting, maintenance, and support are associated with recurring costs, generally adding $100-$500 per month to your infrastructure and $1,000-$5,000 per year to support. Generally, this is what freelancers charge: $50-$150 per hour, while agencies usually charge $100–$300 per hour. Comprehensive security measures and detailed documentation may also increase the project cost.

Yes, API development can be profitable nowadays. This is not only because there is huge demand for integration and increased functionality of businesses. But, also because of the different models of generating revenue that include subscriptions, pay-per-use, freemium, and licensing. Besides that, scalability and reusability of APIs reduce development costs connected with expansion, while trends in the market, like the growth in microservices, IoT, and mobile applications, increase the need for APIs. It is also worth noting that new features are generally associated with better user experiences, higher retention rate, and can also speed up innovation; therefore, APIs act as a solid accelerator of growth in the tech space.

API stands for Application Programming Interface. It is basically a middleman that enables different software programs to talk between themselves and interchange data.
API defines methods and data formats that may be used by applications to request information and exchange of data. APIs are joining the different services and applications, including web services, mobile apps, and cloud platforms, allowing functions like data retrieving, update, and communication of various software components to be carried out.

Start by creating the company description, the salary range for the position, and the list of skills and experience needed for the Senior REST API Developer position. Find or create the list of the screening questions to use during the screening calls and technical interviews — choose questions relevant to the seniority level and tech stack of the position. If you prefer a different approach and are not prepared to spend time reviewing CVs and preparing for interviews, simply apply and share a project overview with our Lemon.io team. We will then present you with 2–3 qualified developers who have already completed all screening stages and are ready to join your project.

Building a REST API can take between 1-2 weeks for a somewhat simple API with simple CRUD operations and minimal authentication. A medium-complexity API that has multiple resources with basic authentication and some advanced features would take 4–8 weeks to engineer. An API with even more advanced features like OAuth authentication, rate limiting, integration with multiple services, and detailed documentation can run into several months of development time. Again, the duration will vary depending on the experience of the engineering team and the requirements for the API.

The best tech for your REST API really depends on your experience and the nature of your project. For beginners, Flask (Python) or Express.js (JavaScript) will do just fine due to their relative user-friendliness. On the other hand, quite complex projects— like those needing scalability, high performance, and strict maintenance — might need Django or Spring Boot. Also, pick the technology that works with your favorite programming language.

A REST API developer is one who designs, implements, and then maintains RESTful APIs. The developer will also define the requirements of the API, design endpoints and URI structures, and determine the proper HTTP methods for those endpoints. They will additionally develop backend code and integrate it with the database, coupled with high-quality error handling. Most importantly, REST API developers take security measures into place. Developers tune the performance and scalability of the APIs, perform unit and integration testing, and debug issues that arise. They are also responsible for preparing users through comprehensive documentation and examples of usage. The last thing would be maintaining the RESTful API and keeping it running.

Yes, REST API developers are still in high demand due to business needs: relying on APIs for integrating systems, enabling data exchange, and building scalable applications. The need for skilled REST API developers remains strong. Additionally, they play a vital role in facilitating seamless data flow and enhancing overall system functionality and performance.

Yes, you can assess a REST API developer’s abilities during the trial phase. We provide a risk-free paid evaluation period for new clients – up to 20 hours, enabling you to evaluate the developer’s performance on assignments before committing to a subscription.

In case of underperformance and if the developer does not meet expectations, we will introduce you to another remote developer under our guarantee of risk-free replacement.

You can hire a REST API developer through Lemon.io in 48 hours – this time is enough to manually check the relevant REST API developers in our community and find the perfect candidate for you. All the candidates who have already joined the community are pre-vetted, which means that our recruiters have already checked their CVs, the candidates have successfully passed the screening calls and tech interviews, and they are ready to join the interview with the client.
