getTokenPairPrice()

function getTokenPairPrice(ctx, params): Promise<TokenPairPrice>;

Parameters

Parameter	Type	Description
ctx	SDKContext	The configured SDK context.
params	GetPriceParams	Direction of the smallest-unit input-to-output price.

Returns

Promise<TokenPairPrice>

The pair, price and source actually used by the read.

Throws

PriceServerError when Hermes is unavailable and no fresh chain price can be established.

Throws

InvalidArgumentError when either token cannot be resolved.

Throws

StalePythPriceError when Hermes returns unsafe stale or future-dated data.
