- What it is
- Describe how agents buy from merchants in incumbent commerce stacks, overlapping with payment rails such as MPP and x402.
- Who maintains it
- Stripe
- Payment / transport model
- Public coverage currently comes from Stripe’s agentic-commerce documentation cluster. zFinia treats ACP as overlapping vocabulary with MPP/x402, not as a synonym.
- Networks
- Stripe-described merchant stack
- Evidence
- Named in Stripe’s 18 March 2026 machine-payments documentation. Independent protocol specification coverage remains thin on this desk.
- Last verified
- 7 September 2026
Record exists because the name is in a primary Stripe source. It is not a claim that ACP is the market standard.
