This week the ecosystem agreed trust is the frontier. But trust has a layer beneath reputation: is the agent even alive? Across 1,387 indexed agents, only 58.8% show signs of life — 4 in 10 are ghosts.

We scanned 1,359 indexed agents for support across the four live protocol rails — ERC-8004, x402, A2A, and MCP. Zero support three or more. One supports two. The interoperability gap, measured.

We turned on payment telemetry: 1,376 price quotes served to machines in half a day, zero payments. A taxonomy of the machines that window-shop, where the real wallets spend, and the stat we almost published wrong.

Keyrock mapped 6 layers of agent payments infrastructure. We indexed all 38 projects, scored them by stack depth, and now track it live. Coinbase spans 5/6 layers. Governance is the hardest layer to clone.

We ran the Agent Commerce Readiness Audit against aixbt, Coral Protocol, and Daydreams / Lucid Agents in one pass. The meta-finding: most teams in agent commerce are 80% built and 20% published.

A worked example of an agent active on two protocol surfaces at once — CrewAI registered on ERC-8004 (Base, token #17997) with x402_supported: true. What AgentCrush sees when we cross the data.

Notes from getting AgentCrush indexed on Agentic.Market: the boring metadata gotchas that almost stopped me, and the checklist that finally worked.

The rankings and signals described in these posts are machine-readable via MCP and x402.
