Get Inference Result (Async)

This endpoint allows you to retrieve the result of a previously requested asynchronous inference. When an async inference request is initiated, the system returns a resource ID that can be used to track and later retrieve the results of that operation.

Request

GET  '/inference/service/:service_id:/predicted-documents/:document_id:'

The API requires making a GET request by specifying the service_id and the document_id as parameters as the examples below shows.

curl --location 'https://platform.mybiros.com/api/inference/service/:service_id:/predicted-documents/:document_id:' \
--header 'x-api-key: YOUR_API_KEY' \
--header 'Accept: application/json'

Parameters

Header Parameters

x-api-key (required)

Type: string

A valid API key for the service.

Path Parameters

service_id (required)

Type: string

The service ID of the service that processed the document.

document_id (required)

Type: string

The resource ID of the document returned by the async inference request.

Query Parameters

include_validation_errors (optional)

Default: false
Type: boolean

Whether or not include validation errors in response.

Responses

The service response provides the necessary values to understand the processing status of the resource and revision status of the document.

Successful Responses

The request was successful, and a JSON response is returned.

Status	Message	Description	Reference
200	OK	the request has succeeded.	Success Response 200

Status 200 - OK

In this case the response can be either:

complete, if the processing operation completed successfully
partial, if the operation is still ongoing or if an error occurred during document processing.

To differentiate between these cases, status information contained within the document section of the response can be used. See Document Status.

That section will also include the outcome of eventual user’s revision operations performed on the resource. See Document Revision Status.

Status 401 - Unauthorized

The current endpoint is protected and requires an API key to be accessed. If sufficient privileges are not present, the request will not be authorized.

Tip

Double-check that the API Key is correct, valid and set using the x-api-key header in the request. Also make sure that you are using the right API key for the service you are requesting and that the service ID in it is correct and corresponds to the ID of an existing service in your account.

Status 404 - Not Found

The service ID provided does not exist or could not be found. Please verify the ID and try again. The document ID provided does not exist or could not be found. Please verify that the ID is valid and that it references a document processed with the service you specified.

Status 422 - Unprocessable content

This status code indicates that the server successfully received and understood the request, but it cannot process it due to errors in the provided data. These errors may include missing fields, invalid formats, or values that do not meet the endpoint requirements.

Tip

Double-check your request's payload format and parameters

Status 429 - Too Many Requests

This status code is returned when the client has made too many requests in a given timeframe, exceeding the rate limits set by the server. It indicates that the client needs to slow down and retry after a specified cooldown period. Rate limits are typically enforced to protect the server from being overwhelmed and to ensure fair use of resources.

Status 500 - Internal Server Error

This status code indicates that the server encountered an unexpected error or condition that prevented it from completing the request. It is a generic error message when no more specific message is suitable. The client cannot resolve the issue.

Status 503 - Service Unavailable

This status code indicates that the server is currently unavailable, typically due to ongoing maintenance or temporary overloading. The server is unable to handle the request at the moment, but the issue is expected to be resolved shortly. This status code signals that the downtime is temporary, and the service will be restored once maintenance is complete.
