Agentic Web Standards
Originary connects to external protocols through adapters. Each integration handles one standard: HTTP 402 for payments, x402 for settlement, AIPREF for publisher preferences, MCP for tool context, A2A for agent coordination.
x402 (HTTP 402)
Priced API access with signed records. Challenge with HTTP 402, accept payment on your chosen rail, return a verifiable interaction record.
Agent-to-Agent (A2A)
Carry verifiable interaction records through A2A metadata. Prove authorization and policy compliance across agent hops.
MCP Server
Open-source MCP server with five tools for verifying, inspecting, and issuing interaction records. Works with Claude Desktop, Cursor, and any MCP client.
AI Preferences (AIPREF)
Machine-readable AI access policies based on the IETF draft. Publish preferences and enforce them with verifiable interaction records.
Agentic Commerce Protocol (ACP)
Protocol support for agent-initiated commerce. Verifiable interaction records for agent transactions.
