Schema

oracleSpecs object

Page of active oracle specs and corresponding page information.

edges object[]

Page of oracle specs data and their corresponding cursors.

Array [

cursor string

Cursor that can be used to fetch further pages.

node object

External spec data that satisfies the list request.

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

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

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

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 [

Schema

code int32
details object[]
Array [
@type string
A URL/resource name that uniquely identifies the type of the serialized protocol buffer message. This string must contain at least one "/" character. The last segment of the URL's path must represent the fully qualified name of the type (as in path/google.protobuf.Duration). The name should be in a canonical form (e.g., leading "." is not accepted).
In practice, teams usually precompile into the binary all types that they expect it to use in the context of Any. However, for URLs which use the scheme http, https, or no scheme, one can optionally set up a type server that maps type URLs to message definitions as follows:
• If no scheme is provided, https is assumed.
• An HTTP GET on the URL must yield a [google.protobuf.Type][] value in binary format, or produce an error.
• Applications are allowed to cache lookup results based on the URL, or have them precompiled into a binary to avoid any lookup. Therefore, binary compatibility needs to be preserved on changes to types. (Use versioned type names to manage breaking changes.)
Note: this functionality is not currently available in the official protobuf release, and it is not used for type URLs beginning with type.googleapis.com.
Schemes other than http, https (or the empty scheme) might be used with implementation specific semantics.
