+
+If you've published an API project on [RapidAPI](https://rapidapi.com/), you can expand your project's visibility by listing it on Apify Store. This gives you access to Apify's developer community and ecosystem.
+
+---
+
+## Why add your API project to Apify
+
+By publishing your API project on Apify, you'll reach thousands of active users in Apify Store. You'll also get access to the Apify platform's infrastructure: managed hosting, data storage, scheduling, advanced web scraping and crawling capabilities, and integrated proxy management. These tools help you reach more users and enhance your API's functionality.
+
+## Step-by-step guide
+
+The approach is demonstrated on an app built on top of [Express.js](https://expressjs.com/), but with a few adaptations to the code, any API framework will work.
+
+You'll deploy your API as an [Apify Actor](https://apify.com/actors) - a serverless cloud program that runs on the Apify platform. Actors can handle everything from simple automation to running web servers.
+
+### Prerequisites
+
+You’ll need an [Apify account](https://console.apify.com/sign-in) - _it’s free and no credit card is required_. For simple migration and deployment, we recommend installing the Apify CLI:
+
+```bash
+curl -fsSL https://apify.com/install-cli.sh | bash
+```
+
+:::info Other ways to install the CLI
+
+Check the [CLI installation page](https://docs.apify.com/cli/docs/installation) for more details and all the options.
+
+:::
+
+### Step 1: Initialize the Actor structure
+
+Once you have the Apify CLI, run the following command:
+
+```bash
+apify init
+```
+
+The command sets up an Actor project in your current directory by creating `actor.json` (Actor configuration) and storage files (Dataset and Key-value store).
+
+### Step 2: Add Actor logic
+
+The initialization of the Actor is the first important thing. The second is the correct mapping of the PORT. Check the following example for inspiration:
+
+```js
+await Actor.init(); // Initializes the Actor
+
+const app = express();
+const PORT = Actor.config.get('containerPort'); // Specifies the PORT
+const DATA_FILE = path.join(__dirname, 'data', 'items.json');
+
+app.use(express.json());
+
+// Rest of the logic
+```
+
+:::tip Readiness checks
+
+The Apify platform performs readiness checks by sending GET requests to `/` with the `x-apify-container-server-readiness-probe` header. For better resource efficiency, consider checking for this header and returning a simple response early, rather than processing it as a full request. This optimization is particularly useful for resource-intensive Actors.
+
+```js
+app.get('*', (req, res) => {
+    if (req.headers['x-apify-container-server-readiness-probe']) {
+        console.log('Readiness probe');
+        res.send('Hello, readiness probe!\n');
+    }
+});
+```
+
+:::
+
+### Step 3: Test your Actor locally
+
+Once you’ve added the Actor logic, test your Actor locally with the following command:
+
+```bash
+apify run
+```
+
+Now, check that your server is running. Check one of your endpoints, for example `/health`.
+
+### Step 4: Deploy your Actor to Apify
+
+Now push your Actor to [Apify Console](https://console.apify.com/). You’ll be able to do this only if you’re logged in to your Apify account with the CLI. Run `apify info` to check, and if you’re not logged in yet, run `apify login`. This only needs to be done once. To push your project, run the following command:
+
+```bash
+apify push
+```
+
+### Step 5: Run your Actor
+
+After pushing your Actor to the platform, in the terminal you’ll see an output similar to this:
+
+```text
+2025-10-03T07:57:13.671Z ACTOR: Build finished.
+Actor build detail https://console.apify.com/actors/a0c...
+Actor detail https://console.apify.com/actors/aOc...
+Success: Actor was deployed to Apify cloud and built there.
+```
+
+You can click the **Actor detail** link, or go to **Apify Console > My Actors**, and click on your Actor. Now, click on the Settings tab, and enable **Actor Standby**:
+
+![Standby Actor](.//adding_rapidapi_project/standby.png)
+
+:::info Two modes of Actors
+
+Actors can run in two modes: as batch processing jobs that execute a single task and stop, or in **Standby mode** as a web server. For use cases like deploying an API that needs to respond to incoming requests in real-time, Standby mode is the best choice. It keeps your Actor running continuously and ready to handle HTTP requests like a standard web server.
+
+:::
+
+Once you’ve saved the settings, go to the **Standby** tab, and click the **Test endpoint** button. It will start the Actor, and you can test it. Once the Actor is running, you're done with the migration!
