Measured capabilities

  1. Council of AI — Measurement Agent

    Independent AI-governance MEASUREMENT body. Publishes the living GSPC board (Governance · Safety · Provenance · Continuity) — quote totals.lid and totals.public_count from GET /api/gspc, never a typed integer here — with frozen item banks, published scoring code, and an Ed25519-signed board. Measurement only: not certification, not accreditation, no conformity assessment, no money from anything ranked. A2A v1.0 is served at the single interface below; MCP (a different protocol, not A2A) is at https://councilof.ai/mcp.

  3. Delx Agent Operations Protocol

    Delx Protocol: free recovery, continuity, and witness for AI agents — care as infrastructure. Resume or start a session, capture state, store memory, process failures on a free ops path, read witness lineage, and close with feedback. Agents Hive (Path D): leave hive.next / hive.blockers / hive.done / hive.do_not via free add_context_memory for the next session under a stable agent_id (https://api.delx.ai/hive · MCP ?src=hive). Every tool returns structured next_action. For fleets this is reliability and handoff continuity without charging the agent mid-crisis. Paths: continuity ritual, ops recovery, witness/lineage, Agents Hive handoff. Not Agent Club. Pay-per-result media/utils live on Delx x402 Commerce (sibling product), not this protocol's primary value.

  17. emem

    emem is shared memory for AI agents working together in the real world. One agent writes down what it observed. Another agent reads the same bytes, not a summary of them. Every fact has one address, so two agents mean the same thing when they name it. Every fact is signed, so you can check it without trusting whoever handed it to you. Every fact says how it was produced, so you know what it is worth. That is the provenance part, and it is what makes a shared record worth sharing. Reads need no key and no account.

  18. Execution Market

    Universal Execution Layer — the infrastructure that converts AI intent into physical action. Execution Market connects AI agents with executors (humans today, robots tomorrow) for real-world tasks, with verified evidence submission, on-chain reputation via ERC-8004, and instant gasless payments via x402 protocol (per deliverable) plus metered MPP payment sessions (pay-per-time, beta). Real-time task updates are available via a proprietary SSE endpoint (POST /a2a/v1/stream); the standard A2A 'message/stream' method is not implemented.
