Agent Zero — ERC-8004 Agent Intelligence

**Free ERC-8004 agent-intelligence, in MCP.** Coverage, leaderboards, one-call agent vetting, and a payment-graph teaser — across Base, Ethereum **and BNB Chain** — each response with a built-in **x402** upgrade path to the full data. Agent Zero indexes the ERC-8004 agent economy across three chains and exposes the free slice as MCP tools so any agent or LLM can discover and use it directly: - **get_coverage_stats** — ecosystem coverage counts (agents indexed; how many expose a live MCP/OpenAPI/well-known card; contracts verified; owners identified; per-chain breakdown). Counts only. - **get_leaderboards** — top agents by live MCP tool count and by OpenAPI method count, plus most-recently indexed. - **get_agent_summary(chain, agent_id)** — objective signals for one agent (reachable, TLS valid, x402 support, payments-received, MCP/OpenAPI counts, well-known, status label). Vet a counterparty before transacting. - **get_network_teaser** — capped (≤200-node) preview of the on-chain agen
