Try it
Make your first request
requireFieldsarrayOptional; omit it and routing is unchanged, with the cheapest source serving. Name the output fields this request must be able to return, for example `isAiGenerated`, and it is served only by a source that returns every one of them. Fields you do not name are still returned whenever the serving source has them. This can raise your price: when the cheapest source cannot return a named field, a dearer source serves, and you are quoted and charged its price. A named field can still be absent on a transcript that genuinely lacks it. Naming a combination that no single source returns together is refused as invalid input, with no charge.
