Opaque identifier for this pricing option, unique within the vendor agent. Pass this in report_usage to identify which pricing option was applied.
Optionalapplies_to_output_format_ids?: FormatReferenceStructuredObject[]Creative transformers only: scopes this pricing option to specific output formats, so one transformer can price different outputs differently (e.g. a multi-publisher template charging per publisher format). When present, the option applies only to leaves whose format matches one of these; an unscoped option (this field absent) is the default for any output. A build targeting an output that matches no scoped option AND has no unscoped default is rejected with UNPRICEABLE_OUTPUT — never billed at a guessed rate (no silent fallback). Inert for non-creative vendors (signals/governance), which omit it.
A pricing option offered by a vendor agent (signals, creative, governance). Combines pricing_option_id with the pricing model fields. Pass pricing_option_id in report_usage for billing verification. All vendor discovery responses return pricing_options as an array — vendors may offer multiple options (volume tiers, context-specific rates, different models per product line).
