Uploading data does not require authentication, but to query data, you have to submit a username and password.

In PowerShell, you can store the cedentials in a variable (e.g. "$cred")

$cred = Get-Credential

of if you want to send the password directly from script:

$cred = new-object -typename System.Management.Automation.PSCredential -argumentlist "DEMO",(ConvertTo-SecureString "password" -AsPlainText -Force)

Upload Data [POST]

Upload a new or existing object where {Id} is the identifier of the object.

Return value is the hash of the uploaded Object.

PowerShell example ($id is the Identifier and $con is the JSON string):

Invoke-RestMethod -Uri "http://localhost:5000/upload/$($id)" -Method Post -Body $con -ContentType "application/json; charset=utf-8"

Upload XML Data [POST]

Upload a new or existing object where {Id} is the identifier of the object.

Note: XML will be converted into JSON.


Return value is the hash of the uploaded Object.

Get full Data [GET]

Resolves the Blockchain with all hashed values and returns the full object in JSON Format.
http://{URL}/full?id={Id}[&index={revision}] -Credential $cred

http://{URL}/full?{lookupId}={LookupValue}[&index={revision}] -Credential $cred


http://server/full?name=NUC1&index=1 -Credential $cred

Get differential between revisions [GET]

http://{URL}/diff?id={Id}[&index={revision}]|[&lindex={left revision}&rindex={right revision}] -Credential $cred
http://{URL}/diff?{lookupId}={LookupValue}[&index={revision}][&mode=0¦1] -Credential $cred

Diff Modes: Mode 0 returns the full object; Mode 1 returns in jsondiffpatch format

http://server/diff?name=NUC1&index=1 -Credential $cred

Get visual differential between revisions [GET]

http://{URL}/diffvis?id={Id}[&index={revision}]|[&lindex={left revision}&rindex={right revision}] -Credential $cred
http://{URL}/diffvis?{lookupId}={LookupValue}[&index={revision}]|[&lindex={left revision}&rindex={right revision}] -Credential $cred

http://server/diffvis?name=NUC1 -Credential $cred

Query Data [GET]

Get all Objects from the latest block in the chain. Use a JSONPath to filter the result. http://{URL}/query?[JSONPath,..][&$select={KeyName,..}][&$exclude={KeyName,..}][&$where={filter}] -Credential $cred

http://{URL}/query?OS&$select=%23Name,_date&$exclude=$..MUILanguages&$where=OS.BuildNumber==17134 -Credential $cred

New: JSONPath ending with '[]' will convert result to an array: Example: http://{URL}/query?LogicalDisk[] will convert LogicalDisk result into an array.

Query Data including History [GET]

Get all Objects from all blocks in the chain. Use a JSONPath to filter the result. http://{URL}/queryall?[JSONPath,..][&$select={KeyName,..}][&$exclude={KeyName,..}] -Credential $cred

http://{URL}/queryall?OS.Caption,OS.Version&$select=%23Name,_date -Credential $cred

Note: Query all blocks may take a long time to process.

Search [GET]

http://{URL}/search?{free text}&$select=%23Name -Credential $cred

Show History [GET]

Get all index,timestamp and hashid for a specific device.
http://{URL}/history?id={Id}[&index={revision}] -Credential $cred

http://{URL}/history?{lookupId}={LookupValue} -Credential $cred

get all Changes [GET]

Get all Objects that have changed within a specifc timespan (default 24h).
Changetyp: 0 = new; 1 = update; -1 = all
The Timespan Format is separated by '-'. e.g "1-05-00-00" = 1day 5Hours
http://localhost:5000/changes?[age={timespan}][&changetype=-1|0|1] -Credential $cred

http://localhost:5000/changes?age=5-00-00&changetype=0 -Credential $cred

Export [GET]

Eports all blocks of all blockchains and upload to another JainDB. This is required if something does chain on the blockchain logic or if you want to change the hash algorythm etc.

To remove objects during export, the "remove" option can be used to specify a JPath of an Object or Attribute.


Convert an XML Object into JSON and return the JSON without uploading to the blockchain. http://{URL}/xml2json

This function is for testing/validation only. It compares the data stored in the blockchain with the cached full data and returns "true" if the hash is the same or "false" if they are different. http://{URL}/validate?id={Id} -Credential $cred
