Yield
data class YieldXyzGetDefaultsResponse(val data: Map<String, YieldXyzDefaultYieldEntry>? = null, val error: String? = null)
Response from the Portal yield defaults endpoint.
The payload maps a "{caip2}:{TOKEN}" key (e.g. "eip155:1:USDC") to the default yield configured for that chain + token. Unlike most Yield.xyz endpoints, this payload is NOT wrapped in rawResponse; the map lives directly under data.
