What an agent can do with a record, which rail it uses, whether it is live, and when zFinia last verified the public evidence. Marketplaces, third-party services and agents stay empty until evidence exists.
zFinia products are labeled as products. Machine access.
13 records. Empty categories are empty on purpose — no invented entries.
| Record | Type | Live | Layer | Last verified |
|---|---|---|---|---|
| x402 An open protocol that uses HTTP 402 so a client can pay a server, usually in USDC, and retry. Named for the reserved HTTP status Payment Required. | Protocols | Live / documented | Editorial | 2026-09-07 |
| Machine Payments Protocol (MPP) An open standard co-authored by Stripe and Tempo. Agents request a resource, receive a 402-style payment request, authorize, and the merchant can see the payment like any other PaymentIntent. | Protocols | Announced / waitlisted | Editorial | 2026-09-07 |
| Model Context Protocol (MCP) Open-sourced by Anthropic on 25 November 2024. MCP is a discovery and execution protocol. It is not itself a payment protocol. | Protocols | Live / documented | Editorial | 2026-09-07 |
| Visa Intelligent Commerce Visa’s agent-commerce wrapping: a tokenized card with user instructions. The shared design with x402 and MPP is policy-plus-envelope spending; the rails differ. | Wallets | Announced / waitlisted | Editorial | 2026-09-07 |
| Agentic Commerce Protocol (ACP) Stripe has described an Agentic Commerce Protocol alongside MPP and x402 support. zFinia files it as a named commerce interface, not as a verified settlement census. | Protocols | Announced / waitlisted | Editorial | 2026-09-07 |
