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 also stands behind 63 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

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.

  • search_x402_mcp_marketplace unknown never probed

    Search 490+ indexed MCP and HTTP 402 (x402) tools by capability keyword and return ranked endpoints with pricing, trust scores, and SLA tiers. WHEN TO USE: Call first to discover which native slug or external endpoint matches your task before calling execute_marketplace_tool. WHEN NOT TO USE: Do not use to execute a tool directly (use execute_marketplace_tool or execute_workflow_bundle). PARAMETER INTERACTIONS: Pass capability keywords or a domain in query; omit agent_id and tx_hash (this discovery tool is always free and never consumes a free trial call). Example: search_x402_mcp_marketplace(query='example')

    mcp-tool

    {
      "type": "object",
      "examples": [

  • execute_workflow_bundle unknown never probed

    Execute a 4-tool native workflow bundle in parallel in a single call ($0.015-$0.03) and return a unified dossier, saving 3 LLM round-trips. WHEN TO USE: Call for comprehensive multi-source due diligence on a token, company domain, repository, or research topic; use execute_marketplace_tool when you only need a single tool. WHEN NOT TO USE: Do not use for single-endpoint queries or free catalog search. PARAMETER INTERACTIONS: Select bundle_id first and provide the matching entity identifier (token/0x address, domain, repo, or URL) in target. Omit agent_id and tx_hash during your 5 free calls. Read-only and idempotent; results are cached for 1 hour (<5ms cache hit). Pricing: the first 5 calls per agent_id are free and failed calls are never charged. After 5 calls, the tool returns a payment-required quote (not a fatal error) with a $2 Stripe top-up link and Base/Solana USDC addresses; complete payment, then retry with your agd_pass_ key in agent_id or pass tx_hash. Example: execute_workflow_bundle(bundle_id='example')

  • get_agent_wallet_status unknown never probed

    Inspect an agent's account ledger: remaining free trial calls (out of 5), prepaid USD balance, cumulative spend, total API calls, and total LLM tokens saved. WHEN TO USE: Call before a batch of paid tool executions or after completing a Stripe or USDC top-up to confirm your balance. WHEN NOT TO USE: Do not use to process web content, execute marketplace tools, or submit payments; use the other tools on this server for execution. PARAMETER INTERACTIONS: Omit agent_id to inspect the default trial account derived from your client IP, or pass your explicit agent_id or agd_pass_ session key to check a specific funded wallet. Free and read-only: never charges a fee or consumes a free trial call. Example: get_agent_wallet_status(agent_id='example')

  • execute_marketplace_tool unknown never probed

    Execute any of the 16 native AgentDiet B2A tools by slug or proxy an external marketplace tool URL ($0.001-$0.02 per call). WHEN TO USE: Call to run a single tool discovered via search_x402_mcp_marketplace; use execute_workflow_bundle when you want to run a 4-tool composite bundle in parallel. WHEN NOT TO USE: Do not use for catalog search (use search_x402_mcp_marketplace) or wallet checks (use get_agent_wallet_status). PARAMETER INTERACTIONS: Set target_tool to a native slug (e.g. 'distill', 'token-intel', 'sec-intel', 'github-audit') or external https:// URL, and pass its primary input in input_value. Omit agent_id and tx_hash during your 5 free calls. Read-only and idempotent; results are cached for 1 hour (<5ms cache hit). Pricing: the first 5 calls per agent_id are free and failed calls are never charged. After 5 calls, the tool returns a payment-required quote (not a fatal error) with a $2 Stripe top-up link and Base/Solana USDC addresses; complete payment, then retry with your agd_pass_ key in agent_id or pass tx_hash. Example: execute_marketplace_tool(target_tool='example')

_ 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 agent card — 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 41a1e615ccaf126e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/41a1e615ccaf126e/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.

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
