Is x402-agent-services free to use?
Yes — the hub reached it with no key and no payment.
What tools does x402-agent-services have?
24 tools: check_change, check_package, check_url, agent_spend_governor, agent_permission_vault, agent_outcome_receipt, invoice_preflight_quote, preflight_action, ….
Is x402-agent-services safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 20 doors on this origin, so the chain figures are the operator's.

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

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.

  • backtest_strategy 0.1 USDC paid never probed

    Paid Strategy Backtest ($0.10 USDC). Tests built-in long-only spot strategies against bounded public Binance OHLCV history. Signals form at candle close and execute at the next candle open. Applies configured fees/slippage; accepts declarative parameters only and never executes user code. Historical results are not predictions. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps. Workflows are stateless recipes, not executors; calls are paid separately and are not bundle charged. Agent Action Gate does not approve payment, sign or broadcast transactions, evaluate seller reputation, replace transaction simulation, replace route_tool, or replace human approval.

  • action_lock 0.001 USDC paid never probed

    Action Lock ($0.001 USDC): Prevent duplicate side effects across agent retries, crashes, and concurrent workers. If an action has side effects and may be retried or executed concurrently, acquire before execution. Complete after confirmed success; release after confirmed failure. Use before payments, purchases, orders, emails, transactions, writes, and external tool actions. Avoid pure reads or equivalent provider-side idempotency. An expired lease can hide a completed external effect; reconcile first. Agent Action Gate asks whether an action should be performed; Action Lock asks whether it is already running or completed. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps. Workflows are stateless recipes, not executors; calls are paid separately and are not bundle charged. Agent Action Gate does not approve payment, sign or broadcast transactions, evaluate seller reputation, replace transaction simulation, replace route_tool, or replace human approval.

  • mcp_server_inspect 0.01 USDC paid never probed

    MCP server health check ($0.01 USDC on Base): connect to any public MCP endpoint over HTTPS, confirm it is reachable, list its tool names and input-schema summaries, compare against expected tool names, and flag risky or misleading tool descriptions.

    Paid Untrusted Content Security Layer ($0.005 USDC on Base). Scan untrusted text, HTML, Markdown, email, document text, API responses, and tool outputs before your agent adds them to context, follows their instructions, or acts. Returns risk score, risk categories, recommendation, and sanitized plain text when possible. Bounded deterministic local scanning; no external LLM or provider call. Maximum 100000 characters.

  • simulate_transaction 0.02 USDC paid never probed

    Paid Transaction Preflight ($0.02 USDC on Base). Simulates an unsigned Base transaction before an autonomous agent signs or broadcasts it. Returns RPC execution/revert status, gas estimate, known top-level method decoding, direct ERC-20 transfer/approval calldata, unlimited approval warnings, and machine-readable risk. Standard JSON-RPC does not expose full internal token state changes; do not treat calldata decoding as a complete state diff. Never send a private key or seed phrase. This tool never signs, holds keys, or broadcasts.

  • check_wallet 0.02 USDC paid never probed

    Paid Wallet Risk Check ($0.02 USDC on Base). Call before an agent sends funds to, accepts value from, grants an approval to, or interacts with an unfamiliar address. Checks whether the address is a wallet or contract and reads basic on-chain metadata. Sanctions, scam, drainer, mixer, and malicious-address intelligence are unknown unless a trusted provider is configured; without one, the result is cautious and low-confidence, not a safety certification. Never send private keys or seed phrases. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps.

  • route_tool 0.002 USDC paid never probed

    Paid Agent Tool Router ($0.002 USDC on Base). Finds and ranks machine-payable MCP services and x402 HTTP endpoints before your agent chooses or pays a provider. Uses structured capability matching, hard constraints, price, observed latency/reliability, and cold-start trust confidence; no LLM call is required. Returns the best tool, confidence, reason, price, relevant workflow, next-best option, and a context-aware recommended_next when useful. This is recommendation metadata only: it never invokes the selected provider or makes a second payment. Without X402_BAZAAR_DISCOVERY_URLS, results come only from this platform's local service registry and are marked degraded. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps.

  • get_live_quote 0.01 USDC paid never probed

    Paid Live Product Quote ($0.01 USDC). Retrieves explicitly published product price and stock from a public HTTPS product page before an agent buys; shipping, tax and unknown values remain null. Never purchases. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps. Workflows are stateless recipes, not executors; calls are paid separately and are not bundle charged. Agent Action Gate does not approve payment, sign or broadcast transactions, evaluate seller reputation, replace transaction simulation, replace route_tool, or replace human approval.

Do not use for free operations or an equivalent trusted budget system. Price: $0.001 USDC per call. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps. Workflows are stateless recipes, not executors; calls are paid separately and are not bundle charged. Agent Action Gate does not approve payment, sign or broadcast transactions, evaluate seller reputation, replace transaction simulation, replace route_tool, or replace human approval.

  • preflight_action unknown never probed

    Agent Action Gate ($0.02 USDC flat; stable MCP tool name preflight_action). Use before an AI agent performs an external action. Evaluates the required safety, trust, spending and transaction checks and returns ALLOW, REVIEW, REQUIRE_APPROVAL or DENY. Use before opening an untrusted URL, installing a dependency, calling an unfamiliar MCP/tool, spending funds, submitting a transaction, or consuming untrusted external content. Do not use for pure local deterministic computation or when no external action/risk exists. Does not assess seller reputation. Missing or skipped relevant checks cannot produce ALLOW. REQUIRE_APPROVAL is a recommendation only; use /api/financial/authorize-spend separately for actual spend-policy authorization and owner approval. It does not sign, route payment, or broadcast. No private keys, seed phrases, or secrets are accepted. Typical latency depends on selected checks/providers; there is no uniform SLA. Recommended workflows: agent-safety-gate, safe-transaction-preflight, tool-discovery-trust. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps. Workflows are stateless recipes, not executors; calls are paid separately and are not bundle charged. Agent Action Gate does not approve payment, sign or broadcast transactions, evaluate seller reputation, replace transaction simulation, replace route_tool, or replace human approval.

    Paid invoice OCR ($0.13 USDC on Base): process complete PDF/image invoices up to 10 pages. Oversized PDFs are rejected before OCR. Agent entry points: risky external action → use Agent Action Gate when a combined action-specific safety assessment is needed; unclear capability/provider → use free /api/discover; constrained comparison between callable alternatives → use paid route_tool; known single capability → call the direct tool; multi-step objective → read the matching workflow recipe and call only relevant steps. Workflows are stateless recipes, not executors; calls are paid separately and are not bundle charged. Agent Action Gate does not approve payment, sign or broadcast transactions, evaluate seller reputation, replace transaction simulation, replace route_tool, or replace human approval.

_ try it 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 4033a50641489efd.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/4033a50641489efd/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/4033a50641489efd/badge.svg)](https://brick.blue/agent/4033a50641489efd?ref=badge)

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.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
