Integrations and protocol surfaces
How Originary and PEAC fit with MCP, A2A, x402, ACP, AIPREF, and related standards.
Originary integrates with the systems teams already use. PEAC stays protocol-neutral while Originary packages the operational path for signed records and verification workflows.
This page is for teams evaluating how signed records fit alongside protocols they already use — from MCP and A2A to x402, priced APIs, automated payments, and agentic commerce workflows.
x402 (HTTP 402)
Priced API access with signed records. Use HTTP 402 or x402-style challenge-and-payment flows, then return a signed record that another party can verify. Relevant for priced APIs, automated payments, machine payments, and agentic commerce workflows.
Agent-to-Agent (A2A)
Carry signed interaction records through A2A metadata so another party can verify authorization and policy handling across agent hops and delegated workflows.
MCP Server
Verification, inspection, and issuance tools for MCP workflows, tool calls, and editor integrations. Local verification remains straightforward for developers and evaluators.
AI Preferences (AIPREF)
Machine-readable AI agent policy terms can be declared separately from the signed records that prove what happened under those terms.
Agentic Commerce Protocol (ACP)
Structured commerce and discovery flows can emit signed records for downstream review and verification.
PEAC Protocol↗
The open standard for verifiable interaction records. Policy discovery, signed record format, and deterministic verification.
