A successful response.

Schema
    oracleSpec object

    External data spec matching the ID.

    externalDataSourceSpec object
    spec object

    Data source spec describes the data source base that a product or a risk model wants to get from the data source engine. This message contains additional information used by the API.

    createdAt int64
    data object

    Represents the top level object that handles data sources. Data source definition can be external or internal, with whatever number of data sources are defined for each type in the child objects below.

    external object

    DataSourceDefinitionExternal is the top level object used for all external data sources. It contains one of any of the defined SourceType variants.

    ethOracle object

    Contains the data specification that is received from Ethereum sources.

    abi string

    The ABI of that contract.

    address string

    Ethereum address of the contract to call.

    args object[]

    List of arguments to pass to method call. Protobuf 'Value' wraps an arbitrary JSON type that is mapped to an Ethereum type according to the ABI.

    filters object[]
  • Array [
  • conditions object[]

    Conditions that should be matched by the data to be considered of interest.

  • Array [
  • operator ConditionOperator (string)

    Possible values: [OPERATOR_UNSPECIFIED, OPERATOR_EQUALS, OPERATOR_GREATER_THAN, OPERATOR_GREATER_THAN_OR_EQUAL, OPERATOR_LESS_THAN, OPERATOR_LESS_THAN_OR_EQUAL]

    Default value: OPERATOR_UNSPECIFIED

    Type of comparison to make on the value.

    value string

    Value to be compared with by the operator.

  • ]
  • key object

    Data source's data property key targeted by the filter.

    name string

    Name of the property.

    numberDecimalPlaces uint64
    type v1PropertyKeyType (string)

    Possible values: [TYPE_UNSPECIFIED, TYPE_EMPTY, TYPE_INTEGER, TYPE_STRING, TYPE_BOOLEAN, TYPE_DECIMAL, TYPE_TIMESTAMP]

    Default value: TYPE_UNSPECIFIED

    Data type of the property.

  • ]
  • method string

    Name of the method on the contract to call.

    normalisers object[]

    Normalisers are used to convert the data returned from the contract method into a standard format. The key of the map is the name of the property, which identifies the specific piece of data to other parts of the data sourcing framework, for example filters. The value is a JSONPath expression for expressing where in the contract call result the required data is located, for example $[0] indicates the first result. $[1].price would look in the second result returned from the contract for a structure with a key called 'price' and use that if it exists.

  • Array [
  • expression string
    name string
  • ]
  • requiredConfirmations uint64
    sourceChainId uint64

    The ID of the EVM based chain which is to be used to source the oracle data.

    trigger object

    Conditions for determining when to call the contract method.

    timeTrigger object

    Trigger for an Ethereum call based on the Ethereum block timestamp. Can be one-off or repeating.

    every uint64

    Repeat the call every n seconds after the initial call. If no time for initial call was specified, begin repeating immediately.

    initial uint64

    Trigger when the Ethereum time is greater or equal to this time, in Unix seconds.

    until uint64

    If repeating, stop once Ethereum time is greater than this time, in Unix seconds. If not set, then repeat indefinitely.

    oracle object

    All types of external data sources use the same configuration set for meeting requirements in order for the data to be useful for Vega - valid signatures and matching filters.

    filters object[]

    Filters describes which source data are considered of interest or not for the product (or the risk model).

  • Array [
  • conditions object[]

    Conditions that should be matched by the data to be considered of interest.

    Default value: OPERATOR_UNSPECIFIED

    Type of comparison to make on the value.

    value string

    Value to be compared with by the operator.

  • ]
  • key object

    Data source's data property key targeted by the filter.

    name string

    Name of the property.

    numberDecimalPlaces uint64
    type v1PropertyKeyType (string)

    Possible values: [TYPE_UNSPECIFIED, TYPE_EMPTY, TYPE_INTEGER, TYPE_STRING, TYPE_BOOLEAN, TYPE_DECIMAL, TYPE_TIMESTAMP]

    Default value: TYPE_UNSPECIFIED

    Data type of the property.

  • ]
  • signers object[]

    Signers is the list of authorized signatures that signed the data for this source. All the signatures in the data source data should be contained in this external source. All the signatures in the data should be contained in this list.

  • Array [
  • ethAddress object

    In case of an open oracle - Ethereum address will be submitted.

    address string
    pubKey object

    List of authorized public keys that signed the data for this source. All the public keys in the data should be contained in these public keys.

    key string
  • ]
