OracleSet

Creates a new Oracle ledger entry or updates the fields of an existing one, using the Oracle Document ID.

OracleSet Fields

Field	JSON Type	Internal Type	Required?	Description
`Account`	String	AccountID	Yes	This account must match the account in the `Owner` field of the `Oracle` object.
`OracleDocumentID`	Number	UInt32	Yes	A unique identifier of the price oracle for the `Account`.
`Provider`	String	Blob	Variable	An arbitrary value that identifies an oracle provider, such as Chainlink, Band, or DIA. This field is a string, up to 256 ASCII hex encoded characters (0x20-0x7E). This field is required when creating a new `Oracle` ledger entry, but is optional for updates.
`URI`	String	Blob	No	An optional Universal Resource Identifier to reference price data off-chain. This field is limited to 256 bytes.
`LastUpdateTime`	Number	UInt32	Yes	The time the data was last updated, in seconds since the UNIX Epoch.
`AssetClass`	String	Blob	Variable	Describes the type of asset, such as "currency", "commodity", or "index". This field is a string, up to 16 ASCII hex encoded characters (0x20-0x7E). This field is required when creating a new `Oracle` ledger entry, but is optional for updates.
`PriceDataSeries`	Array	Array	Yes	An array of up to 10 `PriceData` objects, each representing the price information for a token pair. More than five `PriceData` objects require two owner reserves.

PriceData Fields

Field	JSON Type	Internal Type	Required?	Description
`BaseAsset`	String	Currency	Yes	The primary asset in a trading pair. Any valid identifier, such as a stock symbol, bond CUSIP, or currency code is allowed. For example, in the BTC/USD pair, BTC is the base asset; in 912810RR9/BTC, 912810RR9 is the base asset.
`QuoteAsset`	String	Currency	Yes	The quote asset in a trading pair. The quote asset denotes the price of one unit of the base asset. For example, in the BTC/USD pair, BTC is the base asset; in 912810RR9/BTC, 912810RR9 is the base asset.
`AssetPrice`	String	UInt64	No	The asset price after applying the `Scale` precision level. It's not included if the last update transaction didn't include the `BaseAsset`/`QuoteAsset` pair. It's recommended you provide this value as a hexadecimal, but client libraries will accept decimal numbers and convert to hexadecimal strings.
`Scale`	Number	UInt8	No	The scaling factor to apply to an asset price. For example, if `Scale` is 6 and original price is 0.155, then the scaled price is 155000. Valid scale ranges are 0-10. It's not included if the last update transaction didn't include the `BaseAsset`/`QuoteAsset` pair.

PriceData is created or updated, following these rules:

New token pairs in the transaction are added to the object.
Token pairs in the transaction overwrite corresponding token pairs in the object.
Token pairs in the transaction with a missing AssetPrice field delete corresponding token pairs in the object.
Token pairs that only appear in the object have AssetPrice and Scale removed to signify that the price is outdated.

Note

The order of token pairs in the transaction isn't important because each token pair uniquely identifies the location of the PriceData object in the PriceDataSeries.

Error Cases

Besides errors that can occur for all transactions, OracleSet transactions can result in the following transaction result codes.

Error Code	Description
`temARRAY_EMPTY`	The `PriceDataSeries` has no `PriceData` objects.
`tecARRAY_TOO_LARGE`	The `PriceDataSeries` exceeds the ten `PriceData` objects limit.
`tecINVALID_UPDATE_TIME`	The `Oracle` object has an invalid `LastUpdateTime` value.
`tecTOKEN_PAIR_NOT_FOUND`	The token pair you're trying to delete doesn't exist in the `Oracle` object.
`tecARRAY_EMPTY`	The `PriceDataSeries` has no `PriceData` objects.
`temARRAY_TOO_LARGE`	The `PriceDataSeries` exceeds the ten `PriceData` objects limit.
