Activate service

1. Go to the Alibaba Cloud homepage and sign up for an Alibaba Cloud account. If you already have an account, skip this step.

2. From the navigation bar on the Alibaba Cloud homepage, select Products > Artificial Intelligence and Machine Learning > Natural Language Processing—Address Purification to open the product details page.

Alternatively, you can enter "Address Purification" in the search bar on the homepage to open the product details page.

a. If you are not signed in, click "Enable Now". You will be taken to the sign-in page. After signing in, click "Go to Console".

b. If you are already signed in, click "Product Console" to open the Address Purification console.

In the console, navigate to the overview page to activate the service. Select the feature category and API that you want to use, then click "Buy Now". This activates the pay-as-you-go model and grants you a free quota to evaluate features and test APIs.

After you use your free quota of 500 calls, choose a purchasing option based on your business needs:

1. Small and medium-sized businesses (fewer than 100,000 calls/month)

We recommend the pay-as-you-go model. This model is automatically enabled when you activate the service in the console. With this model, you can call any API.

Procedure: Go to the console > Overview > Select a feature category > Select a feature > Click "Buy Now"

For more information about pay-as-you-go pricing, see metering and billing—pay-as-you-go.

2. Small and medium-sized businesses (fewer than 25 million calls/month)

We recommend purchasing a resource plan. In the console, go to Service Management and Activation, and then select a service category and a resource plan. With this plan, you can call any API.

Procedure: Go to the console > Service Management and Activation > Select a service category > Click "Purchase Resource Plan"

Note: If this is your first time using the Address Purification service, you must first activate the service. If the service is already active, skip this step.

3. Medium and large enterprises (more than 25 million calls/month)

If you have high call volumes and consistently use one or a few specific APIs, we recommend a monthly subscription. In the console, go to Service Management and Activation and select a service category and a monthly subscription. This service is sold per API, so choose the one that best suits your needs.

Procedure: Go to the console > Service Management and Activation > Select a service category > Click "Subscription"

Note: The default QPS is 10. If this QPS does not meet your business requirements, you can adjust the QPS value. The purchase price increases with the QPS.

Note: If this is your first time using the Address Purification service, you must first activate the service. If the service is already active, skip this step.
