AI commerce protocols

Akii focuses on the client-side data and action layer: approved facts, action paths, public output access, readiness checks, exports, and safety boundaries.

Overview

Understand the protocol landscape around ACP, UCP, MCP, A2A, AP2, AG-UI, A2UI, Schema.org, and Google structured data.

  • MCP support is read-only over approved Commerce Graph data.
  • ACP and AP2 are readiness-oriented; payment execution is outside Akii.
  • UCP, A2A, AG-UI, and A2UI support depends on configured public outputs and graph completeness.

How to read protocol support

Akii uses support labels carefully. Supported means implemented in the product. Partial means a profile, output, or operation exists but does not represent full protocol certification. Readiness means Akii checks and prepares required data. Export means Akii emits structured payloads without claiming native platform execution.

Protocol logos and sources

Protocol pages use protocol/source-specific icons from the official source domains and link to the primary documentation used for public claims.
