We are currently using com.google.ads.googleads.v13.services.GenerateForecastCurveResponse to generate forecast metrics for given keywords.
I see that the new v14 approach is described here
https://developers.google.com/google-ads/api/docs/keyword-planning/generate-forecast-metrics , but no advice is given here about how to generate the complete bid curve, as was possible in v13. Making hundreds of calls to KeywordPlanIdeaServiceClient.generateKeywordForecastMetrics, one for each bid, would be very time-consuming and quickly exhaust our usage quota.
What is the new way to obtain the complete curve, with one API request?
