ACP
Agentic Commerce Protocol (OpenAI, Stripe, Meta): checkout, cart, and delegated payment. Underpins Instant Checkout / Buy in ChatGPT.
What it is. Composable checkout, cart, and delegated-payment blocks for agents. Used by Instant Checkout / Buy in ChatGPT and Checkout for Facebook. Source: research/acp.md
(87 rows, snapshot 2026-10-31, last reviewed 2026-10-03).
Who maintains it. Open standard maintained by OpenAI and Stripe (Meta collaborates). Spec lives at agenticcommerce.dev.
What it is not. A checkout/authorization protocol, not a per-API micropayment. Distinct from x402 and MPP.
Note. ACP research does not confirm Mercado Pago, Mercado Libre, or Tiendanube adoption. See LatAm.

Methodology
- How LupaRiel verifies entries
- On rail hubs, the status is the one on that rail. On the home page and the Index, the most advanced among its rails.
- Machine-readable catalog · /rieles.json
- Spanish hub + full listing · /acp/
Sample entries
These names come from the research tables (snapshot 2026-10-31). LupaRiel does not invent rows, prices, networks, or statuses. The complete listing stays on the Spanish hub.
