Watson OpenScale v2 API | IBM Cloud API Docs

Introduction

Last updated: 2021-02-10

IBM Watson OpenScale is an enterprise-grade environment for AI infused applications that provides enterprises with visibility into how AI is being built, used, and delivering ROI – at the scale of their business.

For details about using IBM Watson OpenScale, see the docs.

Authentication

You authenticate to the API by using IAM. You can pass either a bearer token in an Authorization header or an apikey. Tokens support authenticated requests without embedding service credentials in every call. API keys use basic authentication. Learn more about IAM.

IAM authentication. Replace {token} with the bearer token returned by the IAM authentication service.

curl -X GET --header "Authorization: Bearer {Token}" "https://api.aiopenscale.cloud.ibm.com/<SERVICE_INSTANCE_ID>/v2/data_marts"

Security scheme

Authentication to this API's methods uses one of the following security schemes.

Versioning

API requests require a version parameter that takes a date in the format version=YYYY-MM-DD. When we change the API in a backwards-incompatible way, we release a new version date.

Send the version parameter with every API request. The service uses the API version for the date you specify, or the most recent version before that date. Don't default to the current date. Instead, specify a date that matches a version that is compatible with your app, and don't change it until your app is ready for a later version.

This documentation describes the current version of IBM Watson OpenScale, 2021-02-10. In some cases, differences in earlier versions are noted in the descriptions of parameters and response models.

Error handling

The IBM Watson OpenScale service uses standard HTTP response codes to indicate indicate if a method completed successfully.A 200 HTTP response always indicates success. HTTP response codes with the format 4xx indicate a failure. A 500 HTTP response code usually indicates an internal system error that cannot be resolved by the user.

ErrorResponse

Name	Description
code `integer`	HTTP error code.
error `string`	Human-readable error string, like 'Invalid image file'.

ErrorAuthentication

Name	Description
status `string`	The status of error.
statusInfo `string`	Information about the error.

ErrorHTML

Name	Description
Error `string`	HTML description of the error.

ErrorInfo

Information about what might have caused a failure, such as an image that is too large. Not returned when there is no error.

Name	Description
code `integer`	HTTP error code.
description `string`	Human-readable error description. For example, `File size limit exceeded`.
error_id `string`	Codified error string. For example, `limit_exceeded`.

List data set records (Feedback or Payload records)

GET /v2/data_sets/{data_set_id}/records

Request

Path Parameters

data_set_id
Required*
string
ID of the data set

Possible values: 1 ≤ length ≤ 64, Value must match regular expression [a-z0-9_\-]+
Example: 59e92703-febe-4eda-abfa-09261c48f3dd

Query Parameters

start
date-time
return records with timestamp grather then or equal to start parameter

Example: 2018-01-01T00:00:00Z
end
date-time
return records with timestamp lower then end parameter

Example: 2018-01-31T00:00:00Z
limit
integer
limit for number of returned records. If the value is greater than 1000 than it will be truncated.

Default: 100
offset
integer
offset of returned records
annotations
string[]
return record annotations with given names

Examples:
View
filter
string
Only return records that match given filters. There are two types of filters, separated by commas:
- normal filter (multiple are possible), {field_name}:{op}:{value} — filter records directly
- joining filter (only a single one is possible), {data_set_id}.{field_name}:{op}:{value} — join a data set by transaction_id (the user must ensure it's provided!) and filter by this data set's records' field. Will fail if the user hasn't provided transaction_id for both data sets' records. Filters of different types can be mixed. They are partly compatible with the ones in POST /v2/data_sets/{data_set_id}/distributions.
Available operators: | op | meaning | example | code equivalent | |:----:|:---------------------------:|:------------------:|:------------------------:| | eq | equality | field:eq:value | field == value | | gt | greater than | field:gt:value | field > value | | gte | greater or equal | field:gte:value | field >= value | | lt | less than | field:lt:value | field < value | | lte | less or equal | field:lte:value | field <= value | | like | matching a simple pattern* | field:like:pattern | pattern.match(field) | | in | is contained in list | field:in:a;b;c | [a,b,c].contains(field) |
- - "%" means "one or more character", "_" means "any single character", other characters have their usual, literal meaning (e.g. "|" means character "|")
Examples:
normal_filters
joined_filter
mixed_filters
include_total_count
boolean
If total_count should be included. It can have performance impact if total_count is calculated.
format
string
What JSON format to use on output.

Allowable values: [dict,list]
Default: dict
binary_format
string
Binary data presentation format. By default, the binary field value is encoded to base64 string. If reference is chosen, every binary field is moved to the references section with value set to an uri to the particular field within the record that can be GET in a separate request.

Allowable values: [reference]

Example request

curl -X GET   https://aiopenscale.cloud.ibm.com/openscale/<INSTANCE_ID>/v2/data_sets/<DATASET_ID>/records?start=2021-02-12T00:00:00Z&end=2021-02-13T00:00:00Z&limit=100&format=dict   -H 'Accept: application/json'   -H 'Authorization: Bearer <TOKEN>'
