Custodian API - For Holders

Custodian REST API functions.

The Custodian API provides management functions for maintaining secrets and sensitive data (e.g. keys, Verifiable Credentials) in a secure way:

Key
DID
Credentials

Key management

Key management functions include:

List - lists the available keys
Load - loads a key specified by its alias
Generate - generate a key using the specified algorithm
Import - imports a key
Delete - deletes a specific key
Export - exports public and private key parts (if supported by the underlying keystore)

List keys

The /keys endpoint lists the key available to the Custodian

curl -X 'GET' \
  'https://custodian.ssikit.walt.id/keys' \
  -H 'accept: application/json'

No parameters

{
    "list":
    [
        {
            "algorithm": "string",

Did management

DID management functions enable the following:

- lists the available DIDs
- loads a DID by the specified id
- deletes a DID by the specified url
- creates a new DID
- resolves a DID to a document
- import a DID

For more info on DIDs, go .

List DID

The /did endpoint lists the available DIDs.

E.g. List the available DIDs

Load DID

The /did/{id} endpoint loads a DID specified by:

id path parameter (required) - the DID url string

E.g Load the DID having the id = did:web:walt.id.

Delete DID

The /did/{id} deletes the DID specified by:

url - path parameter (required) - the DID url string

E.g. Delete the DID having id = did:web:walt.id.

Create DID

The /did/create endpoint creates a DID.

The method and keyAlias properties are common for all did-method requests, method being required, while keyAlias - optional (if not specified, a new key will be automatically created using the default algorithm according to the did-method). The method-dependent options have default values, if not specified otherwise. Below are the available properties by did-method.

didWebDomain (default) - "walt.id"
didWebPath (default) - empty-string

version (default) - 1

network (default) - "testnet"

E.g. Create a DID using the web method having the domain set to walt.id.

Resolve DID

The /did/resolve endpoint resolves a DID.

E.g. Reslove the DID having id = did:key:z6MkkLmAVeM3P6B2LJ2xGrK1wVojCoephK4G9VrCcct42ADX.

Import DID

The /did/import endpoint resolves and imports the DID to the underlying data store.

The DID url string.

E.g. Import DID having id = did:key:z6Mkm8NbvDnnxJ2t5zLGSkYGCWZiqq11Axr58xQ3ZG1Jss3z.

Delete credential

The /credentials/{alias} deletes a credential by:

alias - path parameter (required) - the credential's id

curl -X 'DELETE' \
  'https://custodian.ssikit.walt.id/credentials/{alias}' \
  -H 'accept: application/json'

No parameters

Code 200

E.g. Delete the credential with id = urn:uuid:d36986f1-3cc0-4156-b5a4-6d3deab84270

curl -X 'DELETE' \
  'https://custodian.ssikit.walt.id/credentials/urn%3Auuid%3Ad36986f1-3cc0-4156-b5a4-6d3deab84270' \
  -H 'accept: application/json'

Present credential

The /credentials/present endpoint creates a verifiable presentation from the specified credentials.

curl -X 'POST' \
  'https://custodian.ssikit.walt.id/credentials/present' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '<request-body>'
