L1 + L2 Guide

1. How to get x-product-api-key

After purchasing the product, open the usage tab and there will be an access token, which is the value of x-product-api-key. If "-" means it has not been initialized yet, press the Refresh button to initialize it. The Refresh button is also used to reset the access token, at which point the old value will expire.
The access token is shared by all products you purchase.

2. Api Guide

2.1 Use product

This API enables users to pass payload from the API /call that the publisher defined.

Endpoint

Endpoint	`/api/v1/user/products/{productId}/use`
Method	POST

Header

Name	Type	Required
x-product-api-key	String	Y

Path

Name	Type	Description	Required
productId	Integer	Product ID	Y

Body

Name	Type	Description	Required
method	String	Method name	Y
payload	Object	Payload of method	Y
callbackUrl	String		N

Response

Name	Type	Description	Required
code	String	Error code. If code = "0", that mean successful	Y
message	String	Error message. If successful, the message is "success"	Y
data	Object		Y
> taskId	UUID	If the method is asynchronous, this field will be returned	N
> status	String	If the method is asynchronous, this field will be returned and will always be "Pending".	N
> … (any fields)		If the method is an immediate response, the fields will be returned in the format the publisher has defined for this method in the `usage tab`	N

Case 1: method is a task that needs to be processed asynchronously. These tasks are considered to take a considerable amount of time to process and cannot respond immediately in this api's response.

Figure 2.1.1: The method's flow of operations is asynchronous

Then, this Api will respond with a taskId and status: "Pending". We will be able to use this taskId to check the result of this request using the Refresh result api. Refer to this example below with a Gif Generator app:

Example Request:

curl -X 'POST' 
  '<host>/api/v1/user/products/53/use' 
  -H 'accept: application/json' 
  -H 'x-product-api-key: <api_key>' 
  -H 'Content-Type: application/json' 
  -d '{
  "method": "text2gif",
  "payload": {
    "prompt": "a cute girl is smiling",
    "height": 512,
    "width": 512
 }
}
'

Example response:

{
    "code": "0",
    "message": "success",
    "data": {
      "taskId": "f9f0f918-3a27-485a-a92f-11a63a2b3630",
      "status": "Pending",
    }
}

Method text2gif will create a gif file from the data received in the payload. This job will definitely take a long time to process. If the system waits for it to finish processing and return it to the user, it will create a bottleneck that clogs the system. Therefore, the system will return a taskId as the task identifier for this request as status: "Pending" to indicate that this task has been recorded and is in process.

Explain further why we save app usage history in 2 ways. There will be 2 api to get app usage results with normal methods (Refresh result, Get use app histories) and 2 api to get app usage results with chat methods (Refresh result, Get use app histories):

With standard methods, the returned results will be updated to the request record previously saved in the database.

Figure 2.1.2: Data flow of standard method

With chat methods, the returned results will be saved as a new record in the database. This will help display chat message results easily.

Case 2: Method is a job that can be response immediately (for example: querying data from the database, or updating data into the database,...).

Figure 2.1.4: The method's flow of operations responds immediately

It is simply the opposite of case 1. Then all you want from this api will be in its response.

See the example below with the Role Play Chat Bot app

Example Request:

curl -X 'POST' 
  '<host>/api/v1/user/products/324/use' 
  -H 'accept: application/json' 
  -H 'x-product-api-key: <api_key>' 
  -H 'Content-Type: application/json' 
  -d '{
  "method": "listCharacter",
  "payload": {
    "page": 1,
    "size": 10
  }
}
'

Example response:

{
  "code": "0",
  "message": "success",
  "data": {
    "dataType": "META_DATA",
    "data": {
      "characters": [
        {
          "id": "b3971500-f6b5-41b5-a80b-2d9bc9149323",
          "name": "Travel Guide",
          "baseBot": "gpt-3.5-turbo-0125",
          "image": "https://example.com/ecbdbffc-6051-4676-9828-1a15b0d4b187-1049e9d7-1d7a-4890-ad1d-0a94b1917220-1.jpg"
        },
        {
          "id": "335be667-69eb-4bd9-81a2-8f2e110b03d7",
          "name": "Bookworm Betty",
          "baseBot": "llama3-70b-8192",
          "image": "https://example.com/ecbdbffc-6051-4676-9828-1a15b0d4b187-1049e9d7-1d7a-4890-ad1d-0a94b1917220-1.jpg"
        }
      ],
      "total": 2,
      "page": 1,
      "size": 10,
      "pages": 1
    }
  }
}

Role Play Chat Bot app allows users to chat with AI bots, each bot will be able to answer one or more areas well that you need answered. The list of bots has been created by the publisher and stored in the database, so when we need to display the list of bots, we just need to query the database and return the list of available bots. This work is quite light and can be answered immediately in the response of this api. That's why it's called immediate response work. Method listCharacter is an example of such work.

In short, we will have 2 types of data that we can receive from the response of this api.

Asynchronous: The response will always return taskId and status: "Pending". The Refresh result api can be used to get the final result
Synchronous (immediate response): The response will return the data defined by the publisher. There is no taskId and no need to use the Refresh result api to get the final result.

All Jobs (method + payload) will be defined and recorded by the publisher in the Request DTO, Response DTO section in the usage tab. They will also define which methods are synchronous and which methods are asynchronous (immediate response).

In cases where an error occurs:

With error validating field method, payload (invalid, missing): Response returns http error 400 (Bad Request)

Example request:

curl -X 'POST' 
  '<host>/api/v1/user/products/324/use' 
  -H 'accept: application/json' 
  -H 'Authorization: Bearer <access_token>' 
  -H 'Content-Type: application/json' 
  -d '{
  "method": "listCharacter"
}
'

Example response:

{
  "statusCode": 400,
  "error": "BadRequestException",
  "message": {
    "payload": "payload should not be empty, payload must be an object"
  }
}

If it does not fall within the above two errors, the request will be forwarded to the AI server for processing. Then, if the input does not satisfy the AI app's validation, the system will still return the error http 400 (Bad Request) with code as the error code and message as an error returned by the AI app.

For example below with the Gif Generator App, the App has only one method, text2gif. Passing the method gif_gen is not supported, so AI Server returns the error "message": "unsupported method gif_gen" and "code": "GIF_403"

Example Request:

curl -X 'POST' 
  '<host>/api/v1/user/products/53/use' 
  -H 'accept: application/json' 
  -H 'x-product-api-key: <api_key>' 
  -H 'Content-Type: application/json' 
  -d '{
  "method": "gif_gen",
  "payload": {
    "prompt": "a cute girl is smiling",
    "height": 512,
    "width": 512,
    "negativePrompt": ""
    }
}'

Example response:

{
  "code": "GIF_403",
  "statusCode": 400,
  "error": "BadRequestException",
  "message": "unsupported method gif_gen"
}

Regarding the callbackUrl field.

For example, you are developing a Layer 2 app, you have previously purchased a Layer 1 app, and your Layer 2 app needs to use it.
You will still need the Use Product, Refresh result or Refresh result for chat app api to be able to use the layer 1 app.
However, this requires you to proactively retrieve the results (by using the Refresh result or Refresh result for chat app).
To be able to receive results passively, use callbackUrl. Marketplace will proactively call it with the data that is the result of the Layer 1 app.

Figure 2.1.5: The method's flow of operations is asynchronous contain callbackUrl

With the callback api, there are some requirements users need to follow:

Http method: POST
The request header will contain x-marketplace-token,please review before proceeding to ensure that the request is coming from Marketplace
If received, please respond with a status of 200

Note:

If it fails or exceeds the timeout (10s), the system will try to call the api callback every 3s up to 3 times.
The payload of the callback api will include the following fields:

Name	Type	Description	Required
taskId	UUID	Task ID	Y
response	Object	Is the result returned from the corresponding method when using the `Use product` api. The format is defined by the publisher in the response DTO of each method in the `usage tab`	Y
errorCode	Object		Y
> status	String	An error code	Y
> reason	String	Specifically describe the error that occurred	Y
extraType	String	Extra data type. Always is "chat_app"	N

2.2 Refresh result

This api is used to receive the return results of the asynchronous method received from the response of the Use product api. Method has extra_type which is not chat_app

Endpoint

Endpoint	`/api/v1/user/products/{productId}/refresh/{taskId}`
Method	GET

Header

Name	Type	Required
x-product-api-key	String	Y

Path

Name	Type	Description	Required
productId	Integer	Product ID	Y
taskId	UUID	Task ID from the response of api `Use product`	Y

Response

Name	Type	Description	Required
code	String	Error code. If code = "0", that mean successful	Y
message	String	Error message. If successful, the message is "success"	Y
data	Object		Y
> status	String	One of the following values: "Pending", "Completed", "Failed"	Y
> result	Object	Is the result returned from the corresponding method when using the `Use product` api. The format is defined by the publisher in the response DTO of each method in the `usage tab`	N

Continuing the example with Gif Generator above, below is an example result of method text2gif for the cases Pending, Completed, Failed

Example Request:

curl -X 'GET' 
  '<host>/api/v1/user/products/53/refresh/800e5ab2-a267-4283-95a0-ddd7d095cc63' 
  -H 'accept: application/json' 
  -H 'x-product-api-key: <api_key>'

Example response for Pending:

{
  "code": "0",
  "message": "success",
  "data": {
    "status": "Pending"
  }
}

Example response for Success:

{
  "code": "0",
  "message": "success",
  "data": {
    "status": "Completed",
    "result": {
      "data": "https://example.com/GIFGenerator/5e7e1a54-386a-42d1-a25e-2b30a915e6b1.gif"
    }
  }
}

Example response for Failed:

{
  "code": "0",
  "message": "success",
  "data": {
    "result": {
       "error": [{"message": "Save file error"}]
    },
