Subscribing to an OCR Service

You can use either of the following ways to subscribe to an OCR service:

Pay-per-Use Billing

  1. Go to the OCR homepage and click Try Now to go to the OCR console.
  2. On the Overview page, select your desired OCR service to subscribe to it. The pay-per-use billing is used by default.

  • If you no longer need to use an OCR service, you can unsubscribe it from the OCR console. After you subscribe to an OCR service, you will be billed for the service on a pay-per-use basis by default. You are billed only when your API is called successfully (status code 2xx is returned). For details about the pricing, see Pricing Details.
  • If you have not subscribed to an OCR service yet, an error message with error code "ModelArts.4204" will be displayed when you call the OCR API.

After the service is subscribed to, you can use the service as needed by referring to Data Requirements and Calling APIs or SDKs.

Buying a Package

  1. Go to the OCR homepage and click Try Now to go to the OCR console.
  2. On the Overview page, select your desired service and click Buy Package in the Operation column. In this case, the package billing mode is used. After your package quota is used up, the billing mode automatically changes to pay-per-use.
