List DID

The /did endpoint lists the available DIDs.

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

No parameters

The list of DID strings

E.g. List the available DIDs

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

[
    "did:key:z6MkkLmAVeM3P6B2LJ2xGrK1wVojCoephK4G9VrCcct42ADX",
    "did:web:my.domain",
    "did:web:walt.id",
    "did:key:z6Mkv58vGsBMwbiyQ3P93MRnYfRgGvn4STEEsj5hFHYe51wu"
]

Load DID

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

id path parameter (required) - the DID url string

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

No parameters

{
    "assertionMethod":
    [
        "string"
    ],
    "authentication":
    [
        "string"
    ],
    "@context":
    [
        "string"
    ],
    "id": "string",
    "verificationMethod":
    [
        {
            "controller": "string",
            "id": "string",
            "publicKeyJwk":
            {

        }
    ]
}

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

curl -X 'GET' \
  'https://custodian.ssikit.walt.id/did/did%3Aweb%3Awalt.id' \
  -H 'accept: application/json'

{
    "assertionMethod":
    [
        "did:web:walt.id#186a1e0a6d42459ba902724fe7643ed4"

        }
    ]
}

Delete DID

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

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

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

No parameters

Code 200

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

curl -X 'DELETE' \
  'https://custodian.ssikit.walt.id/did/did%3Aweb%3Awalt.id' \
  -H 'accept: application/json'

Create DID

The /did/create endpoint creates a DID.

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

{
    "method": "string",
    "keyAlias": "string",
    "method-dependent-options": "..."
}

The DID url string

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.

{
    "method": "key",
    "keyAlias": "string",
    "useJwkJcsPub": "boolean"
}

useJwkJcsPub (default) - false - specifies whether to create a did:key using the jwk_jcs-pub multicodec (code: 0xeb51)

{
  "method": "web",
  "keyAlias": "string",
  "didWebDomain": "string",
  "didWebPath": "string"
}

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

{
    "method": "ebsi",
    "keyAlias": "string",
    "version": "int"
}

version (default) - 1

{
    "method": "cheqd",
    "keyAlias": "string",
    "network": "string"
}

network (default) - "testnet"

{
    "method": "iota",
    "keyAlias": "string"
}

{
    "method": "jwk",
    "keyAlias": "string"
}

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

curl -X 'POST' \
  'https://custodian.ssikit.walt.id/did/create' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
  "method": "web",
  "didWebDomain": "walt.id"
}'

{
    "method": "web",
    "didWebDomain": "walt.id"
}

did:web:walt.id

Resolve DID

The /did/resolve endpoint resolves a DID.

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

{
    "did": "string"
}

{
    "assertionMethod":
    [
        "string"
    ],
    "authentication":

                "crv": "string",
                "kid": "string",
                "kty": "string",
                "use": "string",

            },
            "type": "string"
        }
    ]
}

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