RapidAPI is an API marketplace platform founded in 2015 by Iddo Gino and Mickey Haslavsky. At its peak in 2022, around 4 million developers used the platform to discover and connect to approximately 40,000 APIs from a single account. It raised nearly $273 million from investors, including Andreessen Horowitz, Microsoft, and SoftBank, and reached a $1 billion valuation. Nokia acquired RapidAPI's technology assets in November 2024 to integrate them into its Network as Code platform. Today, RapidAPI operates under Nokia's broader 5G and network API strategy.

What is RapidAPI?

RapidAPI is a marketplace where developers can find, test, and connect to thousands of APIs through one account and a single API key. The platform eliminates the need to hunt down separate API providers, signing up individually, and managing different credentials. Founded in 2015, RapidAPI grew into one of the largest API hubs in the world before Nokia acquired it in November 2024. It remains a key reference point for developers looking to discover and integrate APIs quickly.

How does RapidAPI work?

RapidAPI acts as a gateway between developers and API providers. You create a free account on the website, search for the API you need, and subscribe to a plan. RapidAPI gives you a single key that handles authentication, eliminating the need to manage so many APIs with separate credentials for each service.

When your app makes calls, traffic goes through RapidAPI's gateway, which routes it to the correct provider and delivers the response back. You can also test endpoints directly in the browser console before writing a single line of code.

Benefits of RapidAPI

Using RapidAPI means less time on setup and more time building. The platform delivers that through these five advantages:

1. Consolidated access

One account, one key, and one dashboard to manage API usage. That said, there’s no more juggling separate logins or credentials across different services.

2. Risk-free testing

Developers can test endpoints before committing to them, saving time and preventing wasted work on integrations that don't fit the project.

3. Unified billing

All API costs show up in one place, making it easier for a team to monitor spending across multiple services without chasing down separate invoices.

4. Built-in distribution for providers

API providers gain immediate access to a large developer community without building and maintaining their own developer portal from scratch.

5. Monetize your own APIs

Providers can set up free tiers, usage-based pricing, or subscription plans directly on the platform. Through this platform, they can turn their API into a revenue stream without extra infrastructure.

Who should use RapidAPI?

While RapidAPI was built for developers, it also served a wider range of users. Individual developers used it to plug into ready-made APIs to speed up projects instead of building from scratch. If your work requires you to work with APIs regularly, this platform can help you streamline and organize your work processes.

Startups and development teams used it for consolidated API management and shared billing. At its peak, enterprise customers like Sun Life Financial and Scuderia AlphaTauri used Enterprise Hub to manage internal APIs and reduce sprawl.

What is RapidAPI Hub?

RapidAPI Hub, also known as Enterprise Hub, was RapidAPI's private marketplace product built for large organizations. Companies could deploy their own branded API hub, listing internal APIs alongside approved external ones for their development teams.

This feature includes access controls, usage monitoring, and policy enforcement. The goal of using the RapidAPI Hub was to solve a common enterprise problem: different teams independently using the same APIs without visibility or cost control. It was used by companies that treated APIs as a core part of their infrastructure.

Is RapidAPI free?

Because RapidAPi is a marketplace, it has no singular, unified fee. Instead, each API sets its own pricing. Most APIs offer freemium tiers, featuring a free plan alongside paid subscription tiers.

Here’s how RapidAPI’s pricing tier looks like:

• Basic (free): Many APIs offer a Basic plan, which includes a limited number of requests per month, ranging from 500 to 1,000, for free. It's designed for testing and light use, not production traffic.
• Pro plan: A paid monthly plan that raises your request limit and reduces overage costs. Providers price this tier around $10 to $25 per month, though exact pricing varies by API.
• Ultra plan: A higher-volume tier suited for apps with growing traffic needs. This tier runs around $75 per month and comes with a larger monthly quota and lower per-call overage fees.
• Mega plan: The top-tier paid plan, built for high-traffic production use. Pricing sits around $150 per month, with the highest request limits available before moving into custom enterprise arrangements.

RapidAPI vs Apify vs Postman vs Bruno: Which should you choose?

While all four tools are APIs, each is used to solve different problems. Here’s how they compare to this platform:

RapidAPI

As a marketplace, RapidAPI is where you find, subscribe to, and integrate APIs built by thousands of third-party providers. Everything runs through one account, one key, and one dashboard, which makes it the most practical choice for developers who want to move fast without building from the ground up.

Postman

This development and collaboration tool is designed for teams who want to design, test, and document their own APIs. Though it’s not a marketplace, like RapidAPI, it excels at the build side of the workflow.

Apify

This platform focuses solely on web scraping and data extraction. While it has its own marketplace of pre-built scraping tools, its scope isn’t as broad as RapidAPI's general-purpose hub.

Bruno

This tool is a lightweight, open-source API client designed for local testing of cloud dependency or subscription. It's a lean alternative to Postman for developers who prefer a no-frills tool that lives entirely on their machine.

Bottom line:

• Choose RapidAPI if your goal is discovering and plugging into existing APIs quickly.
• Choose Postman when you're building and maintaining APIs, not consuming APIs others have created.
• Choose Apify when you specifically need web data, and not for general API discovery or integration work.
• Choose Bruno if you want a fast, offline-friendly client for testing your own APIs without paying for a hosted platform.

8. Copy the code snippet and build.

What programming languages does RapidAPI support?

RapidAPI provides ready-to-use code snippets across various programming languages, including PHP, Node.js, Python, Java, cURL, C#/.NET, and several others.

It covers the most common stacks in use today. Also, since the platform generates snippets based on your selected endpoint and parameters, you don’t have to write integration code from scratch.

How to test an API on RapidAPI?

Here’s a step-by step guide on how you test an API on the platform:

1. Log in to your RapidAPI account and open the API's listing page.
2. Select the endpoint you want to test from the left-side menu.
3. Fill in any required request parameters in the console panel.
4. Click the "Test Endpoint" button to send a live request.
5. Review the response in the output panel. Check the status code, headers, and response body.

If everything looks right, copy the generated code snippet in your preferred language and use it in your project.

Can beginners use RapidAPI?

Yes, RapidAPI was designed to lower the barrier to working with APIs. The in-browser testing console lets beginners try out an API without writing any code. Ready-made code snippets in popular languages also reduce the learning curve for those new to API integration. A basic understanding of what APIs are and how requests and responses work will make the experience much smoother.

How does RapidAPI's API listings work?

Each API on the platform has its own dedicated listing page. The page includes the API's name, provider, category, a brief description, available endpoints, documentation, tutorials, pricing plans, and a web-based console for testing directly in the browser.

Providers control most of what appears on their listing, including versioning, they can mark a version as current, keep older ones active, or flag deprecated versions that are no longer usable. A discussions tab lets any logged-in user post questions, feedback, or comments, while providers can manage and respond to those threads. Once you've tested an endpoint and it works the way you need, the listing generates a ready-to-copy code snippet in your preferred language so you can move straight into building.

Is RapidAPI the largest API provider?

Technically, yes, but there’s a caveat. Nokia officially described RapidAPI as the world's largest API hub in its acquisition announcement in November 2024, basing that claim on the volume of APIs hosted on the public marketplace.

At its peak in 2022, the platform counted around 4 million developers and approximately 40,000 APIs, which backed up that title.

However, by the time the acquisition closed, active users had dropped to the thousands and available APIs to the hundreds. In short, the "largest" label reflects where RapidAPI once was, not necessarily where it stands today.
