additional property: Narrative Frame
  type: PropertyValue
  value: Developer-first utility tool enabling informed, efficient resource allocation
additional property: Missing Context
  type: PropertyValue
  value: No mention of data freshness lag; No disclosure of whether rate cards include enterprise discounts or volume tiers; No handling of multimodal or streaming API cost structures
additional property: How the Spin Works
  type: PropertyValue
  value: Combines the credibility signals of open access, live UI interactivity, and alignment with developer pain points to make cost predictability feel more certain and actionable than it is — the tension lies between the clean interface and the messy reality of production API economics, where the tool offers no validation against actual bills or usage telemetry.
