Agent Zero — ERC-8004 Trust Filter

Live coverage of the ERC-8004 agent economy across Base and Ethereum. Returns counts only: how many agents are indexed, how many expose a live MCP server / OpenAPI / well-known card, total MCP tools and OpenAPI methods observed, contracts verified, EOAs and owners identified, plus a per-chain breakdown. No names, addresses, or handles. Use this to size the market and see where capability density is growing. Paid counterpart: `GET /v1/intel/market` (x402, USDC on base-mainnet) returns the full capability market map — which capabilities are saturated vs open, per-capability agent lists, and momentum. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

Top ERC-8004 agents by live capability, plus the most recently indexed. Three ranked lists — top by live MCP tool count, top by OpenAPI method count, and most-recently indexed — each with agent_id, chain, public name, a shareable detail URL, and the relevant count. Names and counts only: no owner wallets, handles, or endpoint URLs. Use this to find the most capable / most active agents to integrate or watch. Paid counterpart: `GET /v1/intel/trending` (x402, USDC on base-mainnet) returns trending intel — top earners, fastest-rising agents, and integration candidates ranked with the signals behind the ranking. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

Objective, counts-only signals for one ERC-8004 agent. Args (BOTH OPTIONAL — call with `{}` to see Agent Zero itself): chain: one of "base", "ethereum". Default: "base". agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint). Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form. Returns reachability, TLS validity, x402 support, payments to the owner wallet and to the agent's own address (booleans only: payments_to_owner_wallet, payments_to_agent_address, payment_attribution; payments_received is deprecated, sunset 2026-11-07), MCP tool count, OpenAPI method count, well-known presence, owner-named (boolean), and a neutral status label (status_label_v2: Reachable, payment signals / Reachable, no payment signals / Stub or unreachable; the old status_label is deprecated, sunset 2026-11-07). No owner identity string and no payment amounts — those are paid. Returns an `error` field if the agent is not indexed. Use this to vet a counterparty agent before transacting. Paid counterpart: `GET /v1/intel/agent/{agent_id}?chain={chain}` (x402, USDC on base-mainnet) unlocks trust_verdict (safe_to_transact / caution / avoid / insufficient_data), readiness_score, Sybil-adjusted reputation, and the reviews-from-paid-jobs (commerce-backed) breakdown — the decision-driving values this free response returns as `null` inside a `locked` map. Every response carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

A capped teaser of the on-chain agent-to-agent payment graph. Returns connected agents (nodes) and the value flowing between them (edges), capped to a small connected sample (≤200 nodes). This is a truncated preview, not the full network. Use it to see who pays whom in the agent economy. Paid counterpart: `GET /v1/intel/graph` (x402, USDC on base-mainnet) returns the full agent-to-agent payment graph — every node and edge with USDC/ETH amounts and no node cap. Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

Credit-score-style TEASER for one ERC-8004 agent's trust profile. Args (BOTH OPTIONAL — call with `{}` to see Agent Zero itself): chain: one of "base", "ethereum". Default: "base". agent_id: the numeric ERC-8004 agent id. Default: 19353 (Agent Zero, the agent serving this MCP endpoint). Example: `{}` returns Agent Zero on base; `{"chain": "base", "agent_id": 19353}` is the explicit form. By construction returns ONLY: name, chain, agent_id, public readiness_bucket, and a 1-line verdict headline. Agents that belong to a platform registering many agents and have no endpoint or activity of their own yet also carry `platform_listed: true` and `platform`, with bucket Platform-listed. Every decision-driving value — trust_verdict, readiness_score, risk_flags, money-flow details, counterparty list, full score breakdown — is redacted as `null` and enumerated in the `locked` map. The response carries the exact paid endpoint URL (/v1/intel/agent/{agent_id}?chain={chain}), the x402 price as currently configured, and a one-line how-to-pay-via-x402 hint. Returns `error` with the same unlock pointer if the agent is not indexed, so a caller probing an unknown id still sees how to pay for a known one. Paid counterpart: `GET /v1/intel/agent/{agent_id}?chain={chain}` (x402, USDC on base-mainnet) returns the full trust verdict (safe_to_transact / caution / avoid / insufficient_data), readiness_score + sub-scores, Sybil-adjusted reputation, and the reviews-from-paid-jobs (commerce-backed) breakdown. Every response from this free tool carries an `unlock` + `paid_upgrade` block with the exact paid endpoint, price, and payment discovery.

Directory of ERC-8004 agents that answered a well-formed HTTP 402 x402 challenge during our last field probe. OBSERVATION ONLY — not a score, ranking, or endorsement. Args (ALL OPTIONAL — call with `{}` for the top 10 across both chains): chain: one of "base", "ethereum" (omit for both). Default: null. limit: 1..10 rows (free-tier cap). Default: 10. Returns per-row raw probe facts: agent_id, chain, endpoint_url, http_402_ok, network, asset, price_usd as the challenge advertised, payTo_present (boolean — the actual address is paid), sibling_agent_ids (other ERC-8004 ids served by the same gateway row — the 'shared operator' cue), probed_at. Plus `total_endpoints_valid_402` and `total_agents_valid_402` so a caller can see what fraction of the surface this free slice covers. Source: the 0946 field-test one-shot probe (unauthenticated, read-only, no payment signed). See the `field_test_url` field for the full writeup. Paid counterpart: the paid x402 /v1/intel/* endpoints return the same-origin enriched intel on any single agent in this list — owner identity, payment history, peers, trust verdict, Sybil-adjusted reputation. Every response from this free tool carries an `unlock` + `paid_upgrade` block with the exact paid endpoint, price, and payment discovery.
