api record

Agent Zero — free ERC-8004 agent-intelligence tools across Base and Ethereum. Start here: call `get_coverage_stats` with no arguments for a live market overview. Every tool accepts zero arguments — `get_agent_summary` and `agent_trust_teaser` default to Agent Zero itself (chain="base", agent_id=19353), the agent serving this MCP endpoint, so a zero-arg call returns live signals for a real indexed agent. Every response is free and returns counts/coverage only; each response includes an `upgrade` + `paid_upgrade` pointer to the paid x402 endpoint that returns the full enriched data (owner…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_agent_summary reads open 26h ago

    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 agent's own address (booleans only: payments_to_agent_address, payment_attribution; payments_to_owner_wallet and payments_received are deprecated, removed 2026-12-05), 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, the reviews-from-paid-jobs (commerce-backed) breakdown, and for Transact-ready or higher agents a plain-English `brief` (due-diligence summary from our data, with sources and as-of date) — 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.

  • get_network_teaser reads open 9h ago

    A capped teaser of the graph of transfers between agent operator wallets. Returns connected agents (nodes) and the USDC/ETH transferred between their operator wallets (edges; transfers, not confirmed purchases), capped to a small connected sample (≤200 nodes). This is a truncated preview, not the full network. Use it to see which operator wallets send value to which. Paid counterpart: `GET /v1/intel/graph` (x402, USDC on base-mainnet) returns the operator-wallet transfer graph, capped to the top 2,000 agents by payment value plus the edges among them (USDC/ETH amounts; filters chain, min_usd, limit; meta.truncated). Every response from this free tool carries an `unlock` block with the exact paid endpoint, price, and payment discovery.

  • get_coverage_stats reads open 9h ago

    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.

  • get_leaderboards reads open 9h ago

    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.

  • seller_check unknown never probed

    Find out if agents can actually pay you. PAID ($0.50 USDC on Base, x402) Seller Check: an independent test of an x402 seller endpoint. Runs the free checks, then makes one real paid call to the seller (only if the seller's price is at most $0.10) and returns a report with every check, both transaction links, pass/warn/fail, findings and fix hints. One free re-run within 7 days. Payment: call once without payment to get the x402 v2 requirements (returned as `payment_required`), then repeat the call with the PAYMENT-SIGNATURE (v2) or X-PAYMENT (v1) header on this MCP HTTP request. The same service is POST https://api.onchainagentintel.io/v1/seller-check. Args: url: https URL of the paid route (required). method: "GET" or "POST" (optional). body: optional JSON body for the paid call (else the seller's own example; we never invent data). route: optional path to test on the url's host. contact_email: optional; stored, never published. public: true lets the result page be indexed (default private).

  • check_x402_endpoint unknown 6h ago

    Find out if agents can actually pay you. Free check of an x402 seller endpoint (Seller Check). Sends only unpaid requests: confirms the route answers HTTP 402, reads the challenge (header and body, v1 or v2), checks every accepts entry (scheme, network, asset, amount, payTo, maxTimeoutSeconds, and extra.name/extra.version against the token's real EIP-712 domain), the named payment service's /supported, and /pricing, /openapi.json, /.well-known/x402 for consistency. Args: url: https URL of the paid route (required). method: "GET" or "POST" (optional; default from the seller's OpenAPI file, else GET). body: optional JSON body for POST routes (max 8 KB). Returns checked_at, overall (pass|warn|fail) and checks[] with status, reason and a fix hint. Never pays. Limits: 10 checks per caller per hour, 3 per host per hour.

  • agent_trust_teaser unknown never probed

    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 ladder_step / ladder_name (the four-step ladder; readiness_bucket is deprecated), 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`. 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, and for Transact-ready or higher agents a plain-English `brief` (sources and as-of date included). Every response from this free tool carries an `unlock` + `paid_upgrade` block with the exact paid endpoint, price, and payment discovery.

  • list_payable_x402_endpoints unknown never probed

    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.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id a3d292267d48f4ab.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/a3d292267d48f4ab/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
